hi, and welcome to Backup Central's Restore it All podcast.
W. Curtis Preston:I'm your host w Curtis Preston, aka Mr.
W. Curtis Preston:Backup, and have with me a guy that just like five minutes
W. Curtis Preston:ago, compared me to a Luddite.
W. Curtis Preston:Prasanna Malaiyandi . How's it going, Prasanna?
Prasanna Malaiyandi:I'm good.
W. Curtis Preston:Did, Did you or did you not compare me to a Luddite?
Prasanna Malaiyandi:I did, and there was a reason I did.
Prasanna Malaiyandi:Right, which was you were.
Prasanna Malaiyandi:Very used to a certain way of operating a, a piece of software,
Prasanna Malaiyandi:right, for the workflow.
Prasanna Malaiyandi:And that software completely updated, but not everything was there.
Prasanna Malaiyandi:And I think your complaint was, I just want things back the way they were.
W. Curtis Preston:Uh, it's, you could put it that way,
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:I'm
W. Curtis Preston:but I'm not, I'm not averse to technology or to new technology.
W. Curtis Preston:I like things to get better, but it does, It is difficult when you're
W. Curtis Preston:using a piece of software and then they're like, You know what?
W. Curtis Preston:We had to just rip and replace.
W. Curtis Preston:Like in order to get, in order to be where we wanted to be, we had to throw
W. Curtis Preston:out the baby with the bath water.
W. Curtis Preston:We had to, you know, you're gonna love what we have.
W. Curtis Preston:Once you get used to it, I hope you hope you don't mind throwing away everything
W. Curtis Preston:you've known after all this time.
Prasanna Malaiyandi:You know what this reminds me of?
Prasanna Malaiyandi:Every time someone updates a backup software app, like completely changes it
Prasanna Malaiyandi:or pushes you, and everyone's like, No.
Prasanna Malaiyandi:I remember, uh, at the old place I used to work that there was, I can't
Prasanna Malaiyandi:remember what version of the backup software it was, but one version,
Prasanna Malaiyandi:they decided to change the color,
W. Curtis Preston:Yeah.
Prasanna Malaiyandi:right, the color of the background, like what their standard
Prasanna Malaiyandi:colors were and everyone complained.
Prasanna Malaiyandi:And they basically had to undo it because they were like, We don't
Prasanna Malaiyandi:understand what these colors are.
Prasanna Malaiyandi:We don't like them.
Prasanna Malaiyandi:Go back to the way they were before.
W. Curtis Preston:Yeah, I don't think my concern was that petty.
W. Curtis Preston:I'm just saying, but I'm just saying when the buttons that I used to press no longer
W. Curtis Preston:work, you know, um, I'm just saying, I just, I just wanna edit my video.
W. Curtis Preston:That's
Prasanna Malaiyandi:But, but, but this is also kind of the.
Prasanna Malaiyandi:Upside and downside of SaaS is things run really fast.
Prasanna Malaiyandi:You get great new features, but because you're building so quickly, not everything
Prasanna Malaiyandi:makes it over in those first releases, and sometimes you just gotta wait.
W. Curtis Preston:Yeah, and I'm, I'm not good at waiting, I don't think.
W. Curtis Preston:I don't know if you've figured that out yet or not.
W. Curtis Preston:I'm not good at delayed gratification.
W. Curtis Preston:But, uh, so, uh, speaking of places that you used to work, I'll
W. Curtis Preston:throw out our usual disclaimer.
W. Curtis Preston:Prasanna works for Zoom.
W. Curtis Preston:I work for Druva Now.
W. Curtis Preston:This is not a podcast of either company and the opinions that you hear are ours.
W. Curtis Preston:And, uh, one of which is apparently a Luddite.
W. Curtis Preston:Um, and if you.
Prasanna Malaiyandi:True opinion.
Prasanna Malaiyandi:It's
W. Curtis Preston:we would love for you to rate us.
W. Curtis Preston:Uh, please rate us by going to your favorite podcatcher.
W. Curtis Preston:Scroll down to where you give us the stars and give us a comment.
W. Curtis Preston:We love the comments.
W. Curtis Preston:It's great to hear from people.
W. Curtis Preston:Um, and, uh, I really love when you reach out to me on LinkedIn.
W. Curtis Preston:That's also great.
W. Curtis Preston:If you wanna join the conversation, be on the podcast, just reach out to me at WC
W. Curtis Preston:preston on Twitter or w Curtis Preston,
@gmail:and, uh, we'll get you on.
@gmail:And, um, so I wanna continue and, and, and almost continue
@gmail:sort of go back to square one.
@gmail:We talked about doing a back to the basics series and for some
@gmail:reason we started the back.
@gmail:We started sort of, I thought we started
Prasanna Malaiyandi:We didn't go far enough back
W. Curtis Preston:We, yeah, we didn't go far enough back.
W. Curtis Preston:And so I thought that a perfect place to go to, to look at the basics of
W. Curtis Preston:backup would be this lovely book.
W. Curtis Preston:Which I believe you helped, uh, edit sir.
W. Curtis Preston:Uh, Modern Data Protection from O'Reilly and Associates, and, um,
W. Curtis Preston:available at a bookstore near you.
W. Curtis Preston:You can get an ebook version of this by going to druva.com/podcast
W. Curtis Preston:and, um, you know, free of charge.
W. Curtis Preston:In the beginning of this book, we have the, you know, what some might consider
W. Curtis Preston:a fluff chapter, which is why we back up.
W. Curtis Preston:And I, I thought there's no more basic question to answer.
W. Curtis Preston:Then why do we do all of this?
W. Curtis Preston:And I, I start the book with a story, which I know I've alluded to
W. Curtis Preston:a couple of times on the podcast.
W. Curtis Preston:I may have even told the whole version, but, hey, we're
W. Curtis Preston:starting from scratch here.
W. Curtis Preston:So I'm gonna tell this version.
W. Curtis Preston:And this is basically how I got into backup.
W. Curtis Preston:I was al, I was already in backup, but this is how I really got into it.
W. Curtis Preston:You
Prasanna Malaiyandi:Wait before you get there,
W. Curtis Preston:yeah.
Prasanna Malaiyandi:do you wanna, because I don't think many of the
Prasanna Malaiyandi:listeners really know, like, what
W. Curtis Preston:How did I,
Prasanna Malaiyandi:you do before you became Mr.
Prasanna Malaiyandi:Backup?
Prasanna Malaiyandi:Before you got into backup?
Prasanna Malaiyandi:Like, like where, Like how did you go from whatever it was
Prasanna Malaiyandi:you were doing into backup?
W. Curtis Preston:Hmm.
Prasanna Malaiyandi:I don't think a lot of people know
Prasanna Malaiyandi:that, and it's very different.
W. Curtis Preston:Well, in, um, January of 1993, I got out of
W. Curtis Preston:the US Navy and I was looking for work in the computer business.
W. Curtis Preston:I had zero experience in computers.
W. Curtis Preston:I had taken, I don't, I don't know if you're, if, do you remember
W. Curtis Preston:the National Radio Institute?
W. Curtis Preston:Do you remember that they, they had the ads back in, back in Popular Science.
W. Curtis Preston:They had an ad like, Build your own
Prasanna Malaiyandi:computer
Prasanna Malaiyandi:Oh, yeah, yeah, yeah, yeah,
W. Curtis Preston:
Speaker:build your own computer.
W. Curtis Preston:
Speaker:I did that while I was out to see, I took this correspondence course.
W. Curtis Preston:
Speaker:This is pre-internet, right?
W. Curtis Preston:
Speaker:Um, you got, you got a, like a book and you worked through that book and
W. Curtis Preston:
Speaker:it was like q and a and then, you know, and then once you got all done,
W. Curtis Preston:
Speaker:then you built a computer and it was an 8088 for those of you I remember.
W. Curtis Preston:
Speaker:So I built my own computer and that was literally the extent of
W. Curtis Preston:
Speaker:my computer experience, right?
W. Curtis Preston:
Speaker:And I got outta the Navy and I managed to get a job at a company called Digital
W. Curtis Preston:
Speaker:Systems, which was a, um, a company that it put in, um, it was called Intelligent.
W. Curtis Preston:
Speaker:Blended call management systems.
W. Curtis Preston:
Speaker:You might call it an auto dialer.
W. Curtis Preston:
Speaker:Um, auto
Prasanna Malaiyandi:Robo caller.
W. Curtis Preston:was a naughty word or a robo caller.
W. Curtis Preston:Yeah, that was a naughty word.
W. Curtis Preston:That was sort of the dumb machine that didn't have the
W. Curtis Preston:intelligence that ours had.
W. Curtis Preston:But anyway, that's what, that was the very first job, but only like,
W. Curtis Preston:Three or four months later, I secured a job via a great connection.
W. Curtis Preston:That would be my wife, um, at what at that time was the second largest credit
W. Curtis Preston:card company, and that would be mbna.
W. Curtis Preston:And, um, I got the job of the backup guy and um, I was in charge of the
W. Curtis Preston:backups for our entire data center, which at that time was 15 servers.
W. Curtis Preston:Um, they were DEC.
W. Curtis Preston:We also had the first computer designed for Unix, AT&T SV 3B2.
W. Curtis Preston:And, um, Uh, and I started with little tiny with, uh, little tiny,
W. Curtis Preston:uh, cartridges and tapes and whatnot.
W. Curtis Preston:Um,
Prasanna Malaiyandi:how big was the environment?
Prasanna Malaiyandi:I know you said 15 servers, but how much data approximately
W. Curtis Preston:so the entire data center, when I left, i d so
W. Curtis Preston:when I joined it was probably the whole data center was 50 gigabytes.
W. Curtis Preston:because it was literally like 11 servers.
W. Curtis Preston:In fact, it was probably smaller than that because our biggest server
W. Curtis Preston:I remember was five gigabytes.
W. Curtis Preston:It was huge.
W. Curtis Preston:It was five gigabytes and it took us all weekend to get a full backup of it.
W. Curtis Preston:Um, And, uh, and the other servers were much smaller than that, so
W. Curtis Preston:it was probably, maybe even 30 gigabytes as the whole data center.
W. Curtis Preston:But by the time I left, it was much larger.
W. Curtis Preston:It was like 300 gigabytes
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:and 100 of those 300 gigabytes was a single server.
W. Curtis Preston:It was a, it was an HP T 500.
W. Curtis Preston:It had a hundred gigabytes.
W. Curtis Preston:And I was like, How in the hell am I ever gonna back all this up?
W. Curtis Preston:Um, because it had a, it had a four gigabyte tape drive and I was like,
W. Curtis Preston:so, Are you gonna give me an FTE to stand here and swap tapes all night?
W. Curtis Preston:And that's how I got my first automated table library, by the way.
Prasanna Malaiyandi:There you go.
W. Curtis Preston:But, uh, yeah, so, um, in the midst of all of that, I had
W. Curtis Preston:been the backup person for a few months and we lost our purchasing database.
W. Curtis Preston:It was an Oracle database.
W. Curtis Preston:Uh, the name of the server was Paris.
W. Curtis Preston:It had been recently migrated.
W. Curtis Preston:It had only been on Paris.
W. Curtis Preston:I don't know, like a month or two, a couple of months.
W. Curtis Preston:And the roughly, slightly less time than how long I'd been at
W. Curtis Preston:the company, whatever that was.
W. Curtis Preston:And.
W. Curtis Preston:I did what I was told to do.
W. Curtis Preston:I went, I looked at the logs to see if the dump was good, cuz we used dump in
W. Curtis Preston:those days and the dump wasn't good.
W. Curtis Preston:So then I looked at the day before dump wasn't good, I looked at the
W. Curtis Preston:day before and so on and so on and so on and so on and so on.
W. Curtis Preston:And I finally found the tape that was, um, That was good.
W. Curtis Preston:And it was, uh, six weeks and one day old, and I knew that I had the transaction
W. Curtis Preston:logs along that time, so I was, you know, I'm thinking that that'll work.
W. Curtis Preston:Uh, the only problem was that, um, the, our retention period was uh, six weeks
Prasanna Malaiyandi:Oh my
W. Curtis Preston:so the last good backup was just, had just been overwritten.
W. Curtis Preston:And so I remember, you know, my boss Susan Davidson.
W. Curtis Preston:I remember her standing over me and saying, So let me get this straight.
W. Curtis Preston:We have no backups of Paris whatsoever.
W. Curtis Preston:And I said, That is what I'm saying.
W. Curtis Preston:And.
W. Curtis Preston:You know, to her credit, she attributed the problem to, to bad training.
W. Curtis Preston:That's you Ron.
W. Curtis Preston:Um, to bad training.
W. Curtis Preston:And what what had happened was we had migrated the server.
W. Curtis Preston:Nobody had told me that there was this, this, um, chron job that had been shutting
W. Curtis Preston:the database down for the backups.
W. Curtis Preston:And I learned a lot of valuable lessons, or I took, I, I.
W. Curtis Preston:I don't know a lot of who I am and how I do things come all the
W. Curtis Preston:way back to that first episode.
W. Curtis Preston:I don't like, like a completely separated cron job that's
W. Curtis Preston:doing something for my backup.
W. Curtis Preston:Before I do the backup, I want the backup to kick off the cron job.
W. Curtis Preston:Right?
W. Curtis Preston:What, You know what I'm saying?
W. Curtis Preston:the CRO job kicks off the backup that kicks off the job.
W. Curtis Preston:You know, I need coordination and I've always, you know, when every, when anybody
W. Curtis Preston:starts talking to me about two separate processes that are gonna handle, you
W. Curtis Preston:know, that are gonna do this, if they don't have a handshake mechanism, I
W. Curtis Preston:get very, very nervous because of that.
W. Curtis Preston:Um, cuz I continued to back up the database all the time while
W. Curtis Preston:the database was changing and not putting it into hot backup.
W. Curtis Preston:Uh,
Prasanna Malaiyandi:It's like the case where a lot of people are like, Oh
Prasanna Malaiyandi:yeah, I just take a snapshot, and then someone just dumps that off the tape.
Prasanna Malaiyandi:It's like, what happens if the thing that did the snapshot failed for some
Prasanna Malaiyandi:reason, you're now gonna think you have a successful backup, and guess what?
Prasanna Malaiyandi:You don't.
W. Curtis Preston:Yeah, yeah.
W. Curtis Preston:And I understand that that's something.
W. Curtis Preston:Oracle DBAs fight over the, the DBAs want to be in charge of their
W. Curtis Preston:backups, but the backup person has to be in charge of the backup system.
W. Curtis Preston:So how do you get those two, you know, to, to get together?
W. Curtis Preston:You know, we could have a whole episode just about that.
W. Curtis Preston:Uh, we probably should have an whole
W. Curtis Preston:episode
Prasanna Malaiyandi:I spent quite a bit of my career focused on that one problem.
W. Curtis Preston:Yeah.
W. Curtis Preston:, you did.
Prasanna Malaiyandi:Before you talk about like the reasons we back up, I
Prasanna Malaiyandi:think it's important to state that you back up not because you want to back up.
Prasanna Malaiyandi:It's like you had said, you need to make sure that you're able to recover your
Prasanna Malaiyandi:database, your application, whatever it is, whenever something happens, right?
Prasanna Malaiyandi:That's the entire purpose of doing backups is
W. Curtis Preston:you
W. Curtis Preston:only need to back up if you wanna restore
Prasanna Malaiyandi:Yeah, exactly.
W. Curtis Preston:You know, the only reason I had kids,
Prasanna Malaiyandi:Because you wanted to restore some place,
W. Curtis Preston:No.
W. Curtis Preston:So that I could have a grandkid.
W. Curtis Preston:They're way better than kids.
W. Curtis Preston:She's sitting right outside there.
W. Curtis Preston:She's adorable.
W. Curtis Preston:And she's nine and I'll take her over either of my two kids.
W. Curtis Preston:Uh, but the thing is, you gotta have kids before you can have.
W. Curtis Preston:That's just the way it works.
W. Curtis Preston:Same thing with backups.
W. Curtis Preston:So I've divided the, the reasons that we back up the risks to
W. Curtis Preston:your data into three groups.
W. Curtis Preston:Uh, human disasters, mechanical failures, uh, and natural disasters.
W. Curtis Preston:So, human disasters to me are things that humans cause.
W. Curtis Preston:We can think of all sorts of categories of those.
W. Curtis Preston:And I'm gonna give what I still think is the number, the
W. Curtis Preston:number one reason we restore.
W. Curtis Preston:What's that?
W. Curtis Preston:What do you think that.
Prasanna Malaiyandi:
Speaker:User did something dumb.
W. Curtis Preston:That's exactly right.
Prasanna Malaiyandi:I accidentally deleted a folder and
Prasanna Malaiyandi:I intended to only delete a file.
Prasanna Malaiyandi:Oops.
Prasanna Malaiyandi:Or I think I still, I can't remember.
Prasanna Malaiyandi:I think you have a story, right?
Prasanna Malaiyandi:Where someone had a script that accidentally deleted a file
Prasanna Malaiyandi:server and erased all of the
W. Curtis Preston:in the book.
W. Curtis Preston:Yeah.
W. Curtis Preston:Yeah.
W. Curtis Preston:They were, What they were doing is they were purging home directories
W. Curtis Preston:that were no longer for users that were no longer in the password file.
W. Curtis Preston:. And so they were going, you know, home one and then they went to the, the first
W. Curtis Preston:directory and then they'd look up the name of the directory in the password file.
W. Curtis Preston:And if it wasn't there, cuz the name of the directory was
W. Curtis Preston:just name of the, of the user.
W. Curtis Preston:The problem was home one slash a slash all users beginning with a.
W. Curtis Preston:And so they got to home one A looked up for a, in
W. Curtis Preston:the password
W. Curtis Preston:file they were there and then de Yeah.
W. Curtis Preston:And they were half, they had deleted half the home directories before
W. Curtis Preston:we figured out what was going.
W. Curtis Preston:Oh Gonda.
W. Curtis Preston:Okay.
W. Curtis Preston:So, um, yeah.
Prasanna Malaiyandi:like you said, most of 'em are.
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:it's dumb stuff.
W. Curtis Preston:It's, it's dumb stuff by users, dumb stuff by admins, dumb stuff by developers.
W. Curtis Preston:Right.
W. Curtis Preston:Um, you know, that sort of dumb stuff.
W. Curtis Preston:And then we have bad stuff, right.
W. Curtis Preston:That happens outside.
W. Curtis Preston:This is, I think today we're starting to think of this as.
W. Curtis Preston:You know, the first is, I think the number one reason you need a backup system.
W. Curtis Preston:This is the number one reason you need a good backup system.
W. Curtis Preston:You need a really good backup n dr system, and that is malicious attacks,
W. Curtis Preston:ransomware, you know, malware, um, you know, and internal threats, right?
W. Curtis Preston:Uh, what do we call those?
W. Curtis Preston:Rogue admins,
W. Curtis Preston:right?
W. Curtis Preston:Um,
Prasanna Malaiyandi:Deleting all your data and going out, and I actually
Prasanna Malaiyandi:just read about that recently.
Prasanna Malaiyandi:Uh, who was it?
Prasanna Malaiyandi:I think someone recently got sentenced to jail because, uh, what did they do?
Prasanna Malaiyandi:They had been fired from their company.
Prasanna Malaiyandi:They still had access to the passwords because the company had not cycled them.
Prasanna Malaiyandi:And so they logged into the company, deleted, changed the
Prasanna Malaiyandi:accounts, locked them out.
Prasanna Malaiyandi:I think they might have deleted things as well.
Prasanna Malaiyandi:And then their entire purpose was they wanted to be rehired for higher pay Right.
Prasanna Malaiyandi:And just show their value.
W. Curtis Preston:yeah, I think there was a little problem with this person's logic,
Prasanna Malaiyandi:And so, yeah.
Prasanna Malaiyandi:Do you have rogue admins like this?
Prasanna Malaiyandi:Right?
Prasanna Malaiyandi:Where if you have someone who has a keys to the kingdom, or you don't
Prasanna Malaiyandi:know all the places that people like, you don't have a proper onboarding
Prasanna Malaiyandi:offboarding procedure to lock down your environment and delete things, right?
Prasanna Malaiyandi:You can have people access your data, change things, delete things
Prasanna Malaiyandi:like backup systems, all the
W. Curtis Preston:And, and this, and this isn't a backup thing, but
W. Curtis Preston:what do we learn from that kids?
W. Curtis Preston:Have a proper onboarding and offboarding procedure.
W. Curtis Preston:. I have been let go once or twice in my career, right?
W. Curtis Preston:Uh, sometimes it was layoffs, sometimes it was a difference of opinion, and the um,
W. Curtis Preston:as to whether or not I should be employed.
W. Curtis Preston:I've had at least once where my account got disabled and then I
W. Curtis Preston:got a call like a minute later.
W. Curtis Preston:Right.
W. Curtis Preston:That's an off, that's an off boarding procedure.
W. Curtis Preston:Right?
W. Curtis Preston:And by the way, I wasn't doing anything malicious.
W. Curtis Preston:They weren't that, that was the off boarding procedure was your account was
W. Curtis Preston:disabled, you were told to renew your password basically is what it looked like.
W. Curtis Preston:You were told to renew your password and then boom, you,
W. Curtis Preston:you know, you got the
W. Curtis Preston:you got the call.
W. Curtis Preston:Which is why to this day when I, when my password times out, which it does, right?
W. Curtis Preston:I'm like, Oh, what, what did I do?
W. Curtis Preston:To this
Prasanna Malaiyandi:And it would be bad.
Prasanna Malaiyandi:Well, and it would also be bad if that happened to just coincide with
Prasanna Malaiyandi:a one on one with your manager,
W. Curtis Preston:Yeah.
W. Curtis Preston:Yeah.
W. Curtis Preston:When, when you, um, Uh, yeah, and I had that happen last week where my, where
W. Curtis Preston:my manager, they sent me a thing, you know, I, I have a weekly, you know, one
W. Curtis Preston:on one and, and I had a, it was at three 30 on Monday afternoon, and suddenly it
W. Curtis Preston:was, it was at nine 30 on Monday morning and I was like, Ooh, that's not good.
W. Curtis Preston:What It turned out to be fine.
W. Curtis Preston:Nothing was wrong, but that's what happens, you know, when you've
W. Curtis Preston:been let go once or twice in your
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:But, but, but, I think going back to the point, more people need to start
Prasanna Malaiyandi:thinking about malicious actors,
Prasanna Malaiyandi:right?
Prasanna Malaiyandi:Especially as they're designing backup systems, thinking about
Prasanna Malaiyandi:disaster recovery, right?
Prasanna Malaiyandi:Which is a huge, uh, topic that we always talk about on the podcast, right, is
Prasanna Malaiyandi:you really should be thinking about how quickly, cuz it's not good enough to
Prasanna Malaiyandi:just recover your data anymore, right?
Prasanna Malaiyandi:It's how quickly can you recover your data to recover from like a ransomware
Prasanna Malaiyandi:attack or other things like that.
W. Curtis Preston:And I would say that you should really, especially look at
W. Curtis Preston:the backup system and ask yourself, what kind of damage could Curtis, who's
W. Curtis Preston:running the whole backup system, what kind of damage could Curtis do to us
W. Curtis Preston:if Curtis got pissed off one afternoon?
W. Curtis Preston:Now, this isn't about Curtis.
W. Curtis Preston:This is about what happens if Curtis's account becomes compromised.
Prasanna Malaiyandi:Yep.
W. Curtis Preston:It's not just a rogue admin, it's also someone
W. Curtis Preston:masquerading as a rogue admin.
W. Curtis Preston:And I know that we, uh, at Druva, we added features that, um, that were
W. Curtis Preston:designed specifically to work around that.
W. Curtis Preston:Even if someone compromises your account, we still won't let them
W. Curtis Preston:do the things that they want to do.
W. Curtis Preston:Um,
W. Curtis Preston:And,
Prasanna Malaiyandi:and, even things like mfa, like we've seen a lot of recent
Prasanna Malaiyandi:attacks with MFA and other things, right?
Prasanna Malaiyandi:That isn't a fail safe, right?
Prasanna Malaiyandi:So you need to make sure you have all these various layers to handle
Prasanna Malaiyandi:the risk rather than just putting all your eggs in one basket, be like, Yep,
Prasanna Malaiyandi:that'll protect me cuz it will not.
W. Curtis Preston:So, uh, the second big category, uh, is
W. Curtis Preston:hardware and system failure.
W. Curtis Preston:And I'm gonna go out there and I'm gonna see, see what you think
W. Curtis Preston:about this cuz you've lived.
W. Curtis Preston:The other side a little differently than me.
W. Curtis Preston:Um, I'm gonna say, so when I started my career, this was,
W. Curtis Preston:I don't know, but not equal.
W. Curtis Preston:But it was a significant, it wasn't equal to the dumb user, right?
W. Curtis Preston:Because we would get, we had 12,000 employees.
W. Curtis Preston:We would do an average of 10 restores a day.
W. Curtis Preston:From users calling in.
W. Curtis Preston:My favorite was a user that called in and said that they needed a file to be
W. Curtis Preston:restored and it was called resume.Doc.
W. Curtis Preston:And I'm like, Really?
W. Curtis Preston:Is that what that file is called?
W. Curtis Preston:Resume dot doc?
W. Curtis Preston:Yeah.
W. Curtis Preston:It's really important that I have this restored.
W. Curtis Preston:Okay.
W. Curtis Preston:All right.
W. Curtis Preston:Um, no, you know, no judgment, but, um,
Prasanna Malaiyandi:You're like, Shall I restore it to an alternate location
Prasanna Malaiyandi:like another, a future employer,
W. Curtis Preston:Yeah.
W. Curtis Preston:Try to grok this.
W. Curtis Preston:Okay.
W. Curtis Preston:Back then we had servers running on hard drives, and by that I
W. Curtis Preston:mean individual hard drives.
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:Right.
W. Curtis Preston:The, the most failing thing in the data center, we would have a server running the
W. Curtis Preston:whole environment, and then the data would be stored on a series of hard drives.
W. Curtis Preston:There was no raid.
W. Curtis Preston:Right.
W. Curtis Preston:And so a single, So if you
Prasanna Malaiyandi:Drive failures, which are very, very high.
W. Curtis Preston:Yeah, well, if you had like 10 drives, you didn't have you.
W. Curtis Preston:You had 10 single points of failure, right?
W. Curtis Preston:Wasn't just one single point of failure.
W. Curtis Preston:You had 10 single points of failure.
W. Curtis Preston:So back then, I think mechanical failure and system failure was a much bigger.
W. Curtis Preston:Today we have virtualization and we have raid, and we have failover,
W. Curtis Preston:and we have vMotion and all that
Prasanna Malaiyandi:Yeah,
W. Curtis Preston:I
Prasanna Malaiyandi:You have erasure coding you have?
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:High availability,
Prasanna Malaiyandi:clustering, all the rest,
W. Curtis Preston:We don't, generally it can happen.
W. Curtis Preston:We don't generally restore because of that today.
Prasanna Malaiyandi:typically, Yeah.
Prasanna Malaiyandi:It happens underneath the covers.
Prasanna Malaiyandi:Unless it's an application that isn't.
Prasanna Malaiyandi:Like a modern application, like a lot of environments still are running older
Prasanna Malaiyandi:applications that may not be virtualized.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:And yes, it could, but
W. Curtis Preston:But it's probably still stored on disc
W. Curtis Preston:that's
W. Curtis Preston:RAIDed
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:So the storage side, you might be okay, but maybe the server side
Prasanna Malaiyandi:you might still have issues, Right?
Prasanna Malaiyandi:That you still have to be concerned about if, assuming it's not virtualized
Prasanna Malaiyandi:or you can't
W. Curtis Preston:might go down, but I don't have to reach for my
W. Curtis Preston:backups if the storage is still okay.
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:That's all I'm saying.
W. Curtis Preston:It's generally a human being did something stupid.
W. Curtis Preston:Is the, is the, I, I'm gonna say the most common reason?
Prasanna Malaiyandi:definitely the most common, The only thing I can think of
Prasanna Malaiyandi:from a hardware failure is there are still cases where you might get silent
Prasanna Malaiyandi:data, corruption and other aspects.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:That you still might need to worry about.
Prasanna Malaiyandi:That isn't necessarily human error.
Prasanna Malaiyandi:Well, it's the developer error potentially.
Prasanna Malaiyandi:Right,
W. Curtis Preston:Yeah.
W. Curtis Preston:Yeah.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:But that's the only other thing I can think of where you, Yes.
Prasanna Malaiyandi:It's not necessarily that you have to think about the hardware
Prasanna Malaiyandi:itself failing, but there are still components within it, which might
Prasanna Malaiyandi:lead to data corruption and affecting.
W. Curtis Preston:You know, it's interesting that you mentioned that.
W. Curtis Preston:I'm not sure if I brought up, if I brought up, data corruption
W. Curtis Preston:just happening over time.
W. Curtis Preston:I, I think I'm gonna count that as system failure, as,
W. Curtis Preston:as, as a hardware failure, right?
W. Curtis Preston:Because it's the underlying mechanism.
W. Curtis Preston:Um, I don't know if I mentioned that in the hardware failure section or not.
W. Curtis Preston:Maybe I did, maybe I didn't.
W. Curtis Preston:But, um,
Prasanna Malaiyandi:There you go.
Prasanna Malaiyandi:For our listeners, it's something that isn't in the book.
Prasanna Malaiyandi:If it's not in there,
W. Curtis Preston:Well, it may not, may not be in the book.
Prasanna Malaiyandi:Yep.
Prasanna Malaiyandi:Having worked in storage for so long, it's one of the things that's always on
Prasanna Malaiyandi:my mind, even though I think a lot of people don't think about it, cuz there's
Prasanna Malaiyandi:a lot of scrubbing that happens and all the rest that it's not as likely anymore.
Prasanna Malaiyandi:But it's not that it's been eliminated.
W. Curtis Preston:There, uh, there are those who think that, that, that bit
W. Curtis Preston:rot is a, is a boogeyman that people like you and me use to scare people.
W. Curtis Preston:Um, those people can go pound sand.
W. Curtis Preston:So the next we'll talk about again, something that's very current.
W. Curtis Preston:So I am from Florida, originally from Florida.
W. Curtis Preston:I live in, I live.
W. Curtis Preston:Much better weather.
W. Curtis Preston:Now, down in, in,
W. Curtis Preston:Sango, it's relative
W. Curtis Preston:Um, yeah.
W. Curtis Preston:My, my mother does not like the weather here.
W. Curtis Preston:She thinks it's too cold.
W. Curtis Preston:The idea of getting cold, you know, cool at night is she's,
W. Curtis Preston:does not like that at all.
W. Curtis Preston:I think that's the single greatest feature, possibly of sun ago.
W. Curtis Preston:Um, but I'm speaking of course, of, of natural disasters.
W. Curtis Preston:So we're recording this as they are.
W. Curtis Preston:Recovering from the fourth strongest hurricane ever to hit landfall in
W. Curtis Preston:the us, which is Hurricane Ian.
W. Curtis Preston:I, you know, it was, it was 150 miles an hour.
W. Curtis Preston:I've been in worse.
W. Curtis Preston:I was actually in Houston, and I don't know where Alicia falls, but what
W. Curtis Preston:I remember was 155 miles an hour.
Prasanna Malaiyandi:Hmm.
W. Curtis Preston:Hurricane force winds with Alicia and I was in Houston.
W. Curtis Preston:So you're basically right.
W. Curtis Preston:You're right there on the water.
W. Curtis Preston:Right?
W. Curtis Preston:Um, and.
W. Curtis Preston:That was a mess.
W. Curtis Preston:Right?
W. Curtis Preston:I remember I was in, I was, well, I was in Alvin, which, um,
W. Curtis Preston:shout out to the folks in Alvin.
W. Curtis Preston:It's a tiny little town that's a suburb of Houston, and my mother and her
W. Curtis Preston:husband managed an apartment complex.
W. Curtis Preston:I was a teenager.
W. Curtis Preston:There wasn't enough plywood to cover the windows on both sides.
W. Curtis Preston:So I remember that we covered one side based on the direction of the wind, and
W. Curtis Preston:then when the, when the, uh, eye hit, we took down all the plywood and put
W. Curtis Preston:it on the other side of the building.
W. Curtis Preston:Um, the, just trying to minimize the, you know, the blast radius
W. Curtis Preston:as we talk about in it, right.
W. Curtis Preston:And the thing is, when you, you know, we've got a couple of great episodes about
W. Curtis Preston:this, about recovering from a natural disaster, um, from, from people that
W. Curtis Preston:actually participated in it, and maybe we'll get another one here from Florida.
W. Curtis Preston:But the, the challenges when you look at.
W. Curtis Preston:You know, so I'm looking here at the list that I had in the book.
W. Curtis Preston:Floods, fires, earthquakes, hurricanes, uh, typhoons and cyclones.
W. Curtis Preston:Tornadoes and sinkholes.
W. Curtis Preston:So what's interesting is Florida has all but the earthquakes,
W. Curtis Preston:so well, it doesn't have.
Prasanna Malaiyandi:Typhoons?
W. Curtis Preston:a typhoon goes the other way.
W. Curtis Preston:Right?
W. Curtis Preston:That's what it isn't that what the thing was, the typhoon.
W. Curtis Preston:Um, and remember we had another name of storm I, I never
W. Curtis Preston:even heard of until we had the, the Derecho, um, which is a
Prasanna Malaiyandi:Land
W. Curtis Preston:based hurricane.
Prasanna Malaiyandi:Yep.
Prasanna Malaiyandi:You basically get like a, the giant pattern and the high sustained winds, so
Prasanna Malaiyandi:it basically becomes a land hurricane.
W. Curtis Preston:Yeah, we, The guy that was on here, I remember him saying
W. Curtis Preston:that he was just standing on his porch and he's like, I'm sorry, what is that?
W. Curtis Preston:like just outta nowhere.
Prasanna Malaiyandi:Yeah,
W. Curtis Preston:Um, the, the thing about all of these is that they wipe
W. Curtis Preston:out everything, you know, look at the photos, look at the videos of
W. Curtis Preston:what's happened in, um, in Florida.
W. Curtis Preston:Fort Myers right now is, Um, devastated.
W. Curtis Preston:I think the worst pictures of videos I remember was Katrina, right?
W. Curtis Preston:Because you had the combination of all of this, plus the fact that New
W. Curtis Preston:Orleans was essentially underwater.
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:They were, they were below sea level, right?
W. Curtis Preston:And so you see the pictures of Fort Myers, now everything's
W. Curtis Preston:destroyed, but the water's gone.
W. Curtis Preston:Right now back with Katrina, it was still, the water was
W. Curtis Preston:still
W. Curtis Preston:up.
W. Curtis Preston:You know, bodies were literally still floating around it.
W. Curtis Preston:It was horrible.
W. Curtis Preston:Um, and it, and it, and it made rescue very difficult cuz it meant everything
W. Curtis Preston:had to be boats and helicopters.
W. Curtis Preston:Right.
W. Curtis Preston:Um, but I think that's the number one thing to take away when
W. Curtis Preston:preparing for a natural disaster.
W. Curtis Preston:Is that nothing that you're used to counting on.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:I assume it's
Prasanna Malaiyandi:all gone.
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:So that was what I think we learned with that.
W. Curtis Preston:That person there that came on.
W. Curtis Preston:Um, do you remember he, he talked about the internet.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:I think if I recall, they had an ISP or an msp, and they basically
Prasanna Malaiyandi:were like our employees needed access, internet access to make sure
Prasanna Malaiyandi:things were okay in supporting their customers, and they had no internet.
Prasanna Malaiyandi:So I think people drove like an hour and a half, two hours away to like a
Prasanna Malaiyandi:Starbucks, so then they could log in just so they can continue and have
Prasanna Malaiyandi:access because they needed to keep their business up and running and that
Prasanna Malaiyandi:was the only way they could keep it.
W. Curtis Preston:That that's, that's one problem that they had.
W. Curtis Preston:The other one that they had was that they used LDAP that was headquartered in the US
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:as their authentication system in order to get into the
W. Curtis Preston:system, in order to do the restore,
Prasanna Malaiyandi:Oh, that was, Sorry.
Prasanna Malaiyandi:That was, Yes, that was the, Sorry.
Prasanna Malaiyandi:The one I was talking about was the land hurricane one.
Prasanna Malaiyandi:You're right.
W. Curtis Preston:Oh, oh, right.
W. Curtis Preston:Right.
Prasanna Malaiyandi:a hurricane on a tropical island.
W. Curtis Preston:Right.
W. Curtis Preston:Yeah.
W. Curtis Preston:And the, we, we should put links, I think in the, in the show
W. Curtis Preston:description to these episodes.
W. Curtis Preston:That was a really good episode.
W. Curtis Preston:Like if you wanna know what it's like to actually recover from a
W. Curtis Preston:hurricane, Cause he talked about that nothing was consistent, right?
W. Curtis Preston:That, you know, they, they could, they didn't have consistent power,
W. Curtis Preston:They didn't have consistent internet.
W. Curtis Preston:They, they ended up getting consistent internet by doing,
W. Curtis Preston:uh, you know, satellite-based.
W. Curtis Preston:Internet.
W. Curtis Preston:Right.
W. Curtis Preston:And they didn't need a lot of bandwidth.
W. Curtis Preston:They just needed consistency.
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:Um, They
Prasanna Malaiyandi:like food and where to sleep.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:I think he slept in the office
W. Curtis Preston:Yeah.
W. Curtis Preston:He converted one of the offices into a room and they, he
W. Curtis Preston:ate a lot of rice and beans
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:weeks.
W. Curtis Preston:He
W. Curtis Preston:was there
Prasanna Malaiyandi:and he, and he said he was lucky, right?
Prasanna Malaiyandi:I think a lot of people didn't have food, didn't have clean water,
W. Curtis Preston:right.
W. Curtis Preston:right.
W. Curtis Preston:Well, you look at what's going on now, I mean, Puerto Rico, you know,
W. Curtis Preston:we talked about a lot about Florida.
W. Curtis Preston:Puerto Rico and Cuba are massively hit, right?
W. Curtis Preston:Because they, cuz they're getting hit on both sides at the same time.
W. Curtis Preston:The place is so small.
W. Curtis Preston:Right.
W. Curtis Preston:Puerto Rico especially because they had already been hit by that
W. Curtis Preston:other hurricane not that long ago.
W. Curtis Preston:Um, and you know, it's, it's funny, um, you know, our friends over there at actual
W. Curtis Preston:Tech media, Scott Lowe and company, so they're having their 10th anniversary.
W. Curtis Preston:Congratulations to them, right?
W. Curtis Preston:Um, they scheduled an offsite for their 10th anniversary in October in
W. Curtis Preston:Florida, and they're there this week.
W. Curtis Preston:Right now they're in Central Florida, they're in Orlando.
W. Curtis Preston:They're fine.
W. Curtis Preston:But I just, you know, I wish Scott had reached out to me and said, Hey,
W. Curtis Preston:I'm thinking about doing a thing in Florida, You know, when should I not go?
W. Curtis Preston:And I would've said, September, October.
W. Curtis Preston:Don't go.
W. Curtis Preston:anywhere near,
Prasanna Malaiyandi:Yep.
W. Curtis Preston:don't go anywhere
Prasanna Malaiyandi:
Speaker:Weather's unpredictable.
Prasanna Malaiyandi:
Speaker:You never
W. Curtis Preston:Yeah.
W. Curtis Preston:It's the, it's the, it's the, you know, it's a hurricane season.
W. Curtis Preston:But yeah, that's the big thing is this, but this is why we back up.
W. Curtis Preston:A, a, a natural disaster, um, can just wipe out everything
W. Curtis Preston:in your company, right?
W. Curtis Preston:It, it wipe out, it wipes out the building, it wipes out the
W. Curtis Preston:power to get to your building.
W. Curtis Preston:It wipes out the internet to your building.
W. Curtis Preston:Um, and you have to bring all of that back.
Prasanna Malaiyandi:or you don't bring it back in the current location,
Prasanna Malaiyandi:you bring it back somewhere else.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:I know we talk a lot about disaster recovery, but even
Prasanna Malaiyandi:without disaster recovery, right?
Prasanna Malaiyandi:This is where the 3 21 rule, right?
Prasanna Malaiyandi:The one part, right, of keeping a copy off site.
Prasanna Malaiyandi:Because if your data center gets hit by a hurricane and is
Prasanna Malaiyandi:completely gone, where is your data?
Prasanna Malaiyandi:At least your data should be offsite.
Prasanna Malaiyandi:Someplace far enough away, right?
Prasanna Malaiyandi:Not down the.
Prasanna Malaiyandi:Such that you
Prasanna Malaiyandi:can recover.
W. Curtis Preston:If you're, in Florida, I don't know where the AWS
W. Curtis Preston:regions are for the southeast, but I don't know if any of 'em are in Florida
Prasanna Malaiyandi:I
W. Curtis Preston:But if you're in Florida, you would not have
W. Curtis Preston:your recovery facility, I would think, anywhere in Florida.
W. Curtis Preston:And that's what, that's what's beautiful about that cloud, right,
W. Curtis Preston:is you know, this is why we back up and this is also why we don't store.
W. Curtis Preston:At least one copy of our data anywhere near Right.
W. Curtis Preston:Um, the, I, I, I think I flashback again, back to MBNA,
W. Curtis Preston:and we didn't use Iron Mountain.
W. Curtis Preston:We used a small,
W. Curtis Preston:um,
W. Curtis Preston:media storage company.
W. Curtis Preston:Huh?
W. Curtis Preston:What's that?
W. Curtis Preston:Yeah, Man man, Yeah.
W. Curtis Preston:We used a small, uh, company that was in Wilmington.
W. Curtis Preston:The thing that we liked about this company, they were probably cheaper
W. Curtis Preston:than Iron Mountain, but the thing we liked about this company is that their
W. Curtis Preston:tapes were stored in what used to be a World War II bomb shelter, right?
W. Curtis Preston:So we felt that they were like really, really safe, but.
W. Curtis Preston:. Um, it also meant that anytime there was a hurricane or anything
W. Curtis Preston:or flood threatening to come up the eastern seaboard, we would call them.
W. Curtis Preston:We'd say it's time for the thing.
W. Curtis Preston:And the thing was, they would take all our tapes out of the vault and
W. Curtis Preston:move them up to the third floor.
W. Curtis Preston:Much less physically secure, but a lot less susceptible to flooding
Prasanna Malaiyandi:Yeah, I was just gonna say, yeah, bomb shelter sounds
Prasanna Malaiyandi:amazing until you're dealing with water
W. Curtis Preston:Yeah.
W. Curtis Preston:Yeah.
W. Curtis Preston:Um, I, I highly doubt that they're still using that company,
W. Curtis Preston:but, um, anyway, I mean, yeah.
W. Curtis Preston:So these are the reasons, right?
W. Curtis Preston:What about, you know, we, we, we really didn't mention terrorism,
W. Curtis Preston:but that's up in the, you know, in the human, the human disasters.
W. Curtis Preston:That, that that's a real thing.
W. Curtis Preston:Nowadays, I think you're more susceptible to electronic terrorism
W. Curtis Preston:than you are a physical terrorism.
W. Curtis Preston:We can't completely rule that out,
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:but I think that, I think that the place to start is you
W. Curtis Preston:first have to build a DR system that works, that would allow you to recover.
W. Curtis Preston:Outside of the, you know, make that part of your core design.
W. Curtis Preston:And then the next would be you need to build a ransomware, you know,
W. Curtis Preston:electronic attack response system.
W. Curtis Preston:Because it's, it's the DR piece is, is a subset of that.
W. Curtis Preston:So, you know, to, to just summarize, I think the whole thing is that there,
W. Curtis Preston:there are, um, there are just so many things that can happen to your data
W. Curtis Preston:that is your company's lifeblood.
W. Curtis Preston:That's why we back up and, and, you know, and I'll borrow a line from Shakespeare.
W. Curtis Preston:Uh, that I use every once in a while when we're talking about some, we're
W. Curtis Preston:gonna talk about the, the places that we need to back up, I think next.
W. Curtis Preston:When I get to arguing with people about whether or not I should back up SaaS,
W. Curtis Preston:one of the phrases that I, that I, um, That I like to use is there are more
W. Curtis Preston:things in heaven and earth than are dreamt of in your philosophy Right.
W. Curtis Preston:I think I quoted that.
W. Curtis Preston:I hope I quoted that well.
W. Curtis Preston:But basically there are so many ways that your data can get, uh, uh, fubar.
W. Curtis Preston:That's a, that's a military acronym.
W. Curtis Preston:You're familiar with that one?
Prasanna Malaiyandi:Yep.
Prasanna Malaiyandi:I know that one.
W. Curtis Preston:Um, and look it up if you dunno what that means.
W. Curtis Preston:Um, and.
W. Curtis Preston:That's why we back up and that's why, you know, Yeah, I, I I don't know.
W. Curtis Preston:I don't, I don't suffer the fools that want it, that
Prasanna Malaiyandi:Well, well, and I know back to the basics, right?
Prasanna Malaiyandi:We've been talking a lot about in a corporate environment,
Prasanna Malaiyandi:but these same risks also apply to your personal data as well.
W. Curtis Preston:every single one.
Prasanna Malaiyandi:Yep.
W. Curtis Preston:And some more than others.
W. Curtis Preston:Mechanical failure, much more likely in your laptop.
W. Curtis Preston:Um, less likely today than it was 20 years ago when we were
W. Curtis Preston:using rotating hard drives.
W. Curtis Preston:Um, and yeah, still possible.
W. Curtis Preston:I will just say this, the most unreliable piece of equipment on your desk is
W. Curtis Preston:that mechanical, USB hard drive that you're using as a backup right now.
W. Curtis Preston:Tell me I'm wrong.
Prasanna Malaiyandi:Yeah.
W. Curtis Preston:Tell me I'm wrong.
W. Curtis Preston:Yeah.
W. Curtis Preston:That, that's why, that's why I'm, I'm much more of a fan of,
W. Curtis Preston:of, you know, of cloud backup.
W. Curtis Preston:And by the way, you know, you wouldn't be a Druva customer, because, you
W. Curtis Preston:know, we don't do the, the consumer thing, but there are so many other
W. Curtis Preston:things that you do for consumers, right?
W. Curtis Preston:There are cloud services to backup your important stuff.
W. Curtis Preston:Um, yeah.
W. Curtis Preston:Anyway, well have we, have, we beat the drum enough
Prasanna Malaiyandi:I
W. Curtis Preston:Prasanna?
Prasanna Malaiyandi:And just for our listeners, I think the next topic on
Prasanna Malaiyandi:back to the basics will be what, Curtis, what are we, where do we go from here?
Prasanna Malaiyandi:Where do we go from here?
W. Curtis Preston:Good question.
W. Curtis Preston:We talk a lot about some techy stuff.
W. Curtis Preston:One of the things that you hear us say a lot is that you, um, you need to go to
W. Curtis Preston:the business and you need to get your, um, you know, your service level agreements
W. Curtis Preston:and things like RTO and RPO . You need to get that from the business, and you
W. Curtis Preston:need to get the business to buy into this whole thing that you're gonna do,
W. Curtis Preston:because you can't, you can't be, you.
W. Curtis Preston:Batman is not a good backup person, right?
W. Curtis Preston:You can't be alone in the night, uh, with no funding doing a backup system.
W. Curtis Preston:It's a horrible way to do.
W. Curtis Preston:You gotta get the backup.
W. Curtis Preston:You gotta get the, the powers that be as into backup as you are.
W. Curtis Preston:, Right?
W. Curtis Preston:Maybe not as, as into backup as Daniel Rosehill.
W. Curtis Preston:Um,
Prasanna Malaiyandi:We love you Daniel
W. Curtis Preston:I love you, Daniel.
W. Curtis Preston:The backup, anarak, so that's what we're gonna talk about next
W. Curtis Preston:is how to, how to bring, how to bring the business into this.
W. Curtis Preston:Um, so good.
W. Curtis Preston:So thanks for asking me that.
W. Curtis Preston:It was a good, it's a good follow.
W. Curtis Preston:All right, and I'll just, again, I'll mention, um, if you're interested in
W. Curtis Preston:all these topics, you can get a free copy, uh, you know, an ebook copy
W. Curtis Preston:of my book, latest book, Modern Data Protection by going to druva.com.
W. Curtis Preston:Druva.com/podcast and, um, uh, download your own copy so you can follow along
