          I've been wondering about this.

          What if I have a RAID1 array and a bunch of spare drives. I pull a drive from the array and plug one of the spares in. Now the pulled drive is a backup and the array is syncing onto the new disk.

          So long as the array does the right thing when I put one of the old disks in (ie it syncs over the old data and doesn't sync from it (ouch)) I should be able to carry on like this and maintain a backup set. Right?

            If you plan on doing something like that regularly, you should consider doing a 3-way mirror (3 disks, RAID-1) so that you're left with two good disks after pulling one. Easily done in Linux software RAID or the better (real hardware) RAID controllers.

      Nice subtle troll there. As everyone knows RAID is not a backup.

      • Raid is a backup, if you have drive mirroring going on then you have an active backup at all times.
    • If it's one thing you take from backup this, please let it be this: Redundancy is not backup. Many tears have been shed from misunderstanding this.

      • The formal definition might not be correct but logically if you have all the information being mirrored then you do have a backup! Well many people wont agree and I'm not saying they're wrong, having a Raid setup does give you a "copy" of your data and therefore means you have a backup. A backup good enough for what I need, well it might not suit the business world, it does suit my house perfectly.

          CloudGates.net does indeed look like a useful service.

          This technote from 'AWS Blog' explains how to use the more standard and better documented Amazon S3 Data buckets to automatically offload data after a specified time to Amazon Glacier storage. The trick is to create a lifecycle rule. I'm inclined to try this, once I get myself better organized, although CloudGates also looks very worthy.

They do security right, have no space limit or speed throttling. Take the hit and start backing stuff up. It will eventually finish and at some point you may be glad you did it. Of course, you could also back up using their client to a friends machine, and vice-versa, but I figure their hosting is less trouble (and you could always do both).

    I managed to go 16 years in the IT world, first as a sys admin and now up through an awesome mid-level management position, without any serious data management scares. (And by 'awesome', I mean I work for demoralizing leadership and I've hit a glass ceiling which will force me to go find another company to work for if I want any shot at career advancement.) I've always made sure there's many, many layers of redundancy and good processes in place.

    That was until three weeks ago.

    We use Microsoft DFS to sync data between two sites. Because of some other things going on, we had to turn DFS off for 3 weeks. We thought we had everyone transitioned to using the "master" file repository, the one that gets backed up every night, etc, etc. The day we turned on DFS back on, all hell broke loose.

    Oh - and this is fairly important stuff: 10 years worth of CAD, design, and legal paperwork. It's a few terabytes worth. For our medium-size company, this is basically everything that we hold near and dear.

    The first thing that happened is DFS completely puked and completely trashed BOTH filesystems. Fantastic, Microsoft - what a wonderful piece of shit DFS is. Fairly quickly we had to face some data integrity issues. First, we discovered apparently there was a fella at the remote site that was using the copy of files there. Great.. through a fairly manual process we were able to retrieve most of his changes to the dataset. Next, we fairly quickly gave up on trying to fix the DFS - on the advice of Microsoft it seemed to be fairly hopeless.

    This is where shit gets real.

    Our head sys admin had been troubleshooting an issue with a drive in a RAID'ed NAS backup device had failed. All the other backups had been shifted to other NAS devices, but that backup was so large that it apparently had just been failing. While looking for that, we also discovered the quarterly backup from December had failed (that's the point where I wanted to put on my manager hat and go rip someone a new one, but decided that probably wouldn't be the most productive thing at the moment and could save that little teachable moment asskicking until after we were out of the woods.) Now, the sys admin hadn't been completely foolish, before turning DFS back on he had run some full backups using a different NAS device.

    In a f*cking brilliant stroke of disastrous luck, when we went to perform the recovery we discovered that RAID array on the backup NAS device also had corruption.

    Now, how bad the corruption was and what exactly that meant remained to be seen. The backups had completed without error, it was the NAS filesystem itself that was throwing the errors. The NAS was still running and our backup software seemed to recognize the backup catalogs on it. Ok, other than what seemed to one potentially corrupt backup, it was seeming like the next best case scenario was a quarterly backup from September, and I was also staring a complete set of disks from 2010 dreading the thought of bringing them back online. Well, with nothing to do other than try a restore, we pressed the button.

    That's when I went home mid-morning, chainsmoked four cigarettes on my porch and wondered what would happened if everything went south. In other words, I was contemplating my next job.

    'Lo and behold, and restore worked. We had to merge all kinds of things back together to get a complete copy reassembled, then we still had to get DFS working (which took four days of syncing over the WAN.) When it was all said and done, it looked like there were just two files from one set of changes that we couldn't recover.

    I think I'll go double check on the backup jobs now.

    • Wait ... so you read /. and you thought a Microsoft tool would avoid disasters? I think rapid reading classes are needed - quickly followed by an LTO drive and some tapes.
      • Seriously, I would have picked practically anything but a Microsoft branded solution for syncing the data between sites.

    Amazon Glacier [amazon.com] has really changed my backup strategy since this time last year - I now push all my own, generated content (ie: pictures, documents, things I could never get back if I lost everything) up to Glacier using the free Windows client, Fast Glacier [fastglacier.com]. In February I was charged $0.13 by Amazon for storing ~8Gb of data. I tend to push new content up as and when I create it (for example, after I process holiday snaps, or get back from a day out).

    Day to day file changes are now handled by Windows 8's File History [microsoft.com] feature where my changes are pushed to a small NAS (Dlink DNS-320 [dlink.com]) in my shed (technically off site?) over a Homeplug AV [wikipedia.org] ethernet link. For added security I use the legacy Windows Backup application [arstechnica.com] (still present in Windows 8) to create ~ monthly snapshots of the system which I store on a 320Gb external HDD. This drive is one of two which go back and forth between my parents house each time I got and visit. These disks are encrypted using Microsoft Bitlocker drive encryption [microsoft.com].

    I should get around to properly encrypting my NAS in the shed, I've been looking at encfs [arg0.net].

    • Spideroak for my crucial working files along with local backup here, too; I find it's also helpful at times to have it back up the autosave/temp directories used when I work on them. I just wish that they'd come to their senses and offer a more reasonable pricing scheme -- a lot of users could use a few more GB for breathing room and would pay a few dollars each month (like ~$1/GB) for it, but will never come *close* to 100GB, let alone pay $100-120/year for the useless space, especially if our connection

    I use rdiff-backup [nongnu.org] on each of the machines I administer (my machines and those of my wife, at home and at work, plus laptops). rdiff-backup is nice because it saves the current snapshot as a directory that looks exactly like the one being backed up, so restoring stuff is really very trivial.

    The backup scripts run daily, backing up to the home directory of the user (a /home/$user/backups directory) so that casual deletion means at most a day of work lost. I rsync all those backup dirs weekly to one of three 1TB drives. They are about 60% full each.

    The three of them are rotated arround. One is next to me, one in the basement, and another in a drawer at my office. They get rotated every week.

    Seems pretty solid to me. A lot has to happen to leave me with a serious data loss.

  • I've never had a data disaster, but I still have a somewhat complex setup:
    1. Automatic filesystem (ZFS) snapshots every 15 min on my desktop (home, also used for work from home) and RAID to protect against HW failures.
    2. Unison (http://www.cis.upenn.edu/~bcpierce/unison/) sync between laptop and desktop keeps my home dir in two places (the important bits)
    3. Work files are synced to the organisation's system, and that's probably enough
    4. Rsync backup to external hard drive every ~3 days, drive is otherwise

  • If you don't back up, you'll have to start backing up to restore. If you do backup, you need to test your backups today. For the love of god don't just assume your stuff comes back out ok.

  • One local USB, one Network disk placed right by the exit in case I need to abandon ship in a hurry (Bushfire area). Backing up 1.3 terabytes twice consumes backup day. For the rest of the year I do incremental backups. Even if both backups were lost data could be recovered from the cloud.
  • I've had two data disasters over the years:

    1) In the early 90s, I was a teenager using a trusty Apple IIgs to write & edit my first full-length novel, first on 3.5" floppies and then a 20mb Seagate external hard drive. Two or three years into the project, when a summer of 6-8 hour days working on it had the first full rough draft 99% finished and partway into heavy restructuring/editing, I turned the IIgs on only to have it inform me there was no bootable disk. (I later learned that my mother had just

  • I have spent quite some time last year, working on a disaster recovery plan for my company, and one thing I realised was, that of all the important things you have to do to be able to recover after a total wipe-out, back ups are actually the smallest. This is my list of priorities:

    1. People: we develop software, and it takes something like a whole year before a new developer is fully on top of their game. The sudden loss of even one of them would seriously hurt our ability to perform. How many could we surv
