    I don't have many personal files, but emails get backed up automatically. Photographs get backed once I download them from my camera (and sometimes I even burn them onto a dvd). And other personal files often aren't important, and will only be backed up if I find the time.

    -- Of course I will complain about lack of options.

      When I turn on my personal PC it's backed up to my "server" using rsync, and the server backs up my PC (these computers are 150km from each other).

      Rsync's hard links option makes it easy to take a backup every day of only changed files. I keep any backup that is (of the most recent five) | (less than two weeks old) | (taken on the 5th, 15th or 25th).

    • I use older external hard drives as a backup. So I've got my current 1TB external data drive, and use my older 500GB to back up the important stuff off that. Once I get around to getting a bigger drive, the 1TB becomes the backup drive, and the 500GB goes idle.

For one good example, look at Nexanta - which is the Ubuntu userspace on a Solaris kernel with zfs support and some zfs-enhanced utils. To get all the way there, you almost need a periodic cleanup process - as just a slight offset at the beginning of a file screws up block-based detection of data which is otherwise duplicated but just not aligned to blocks the same way.

      The best of all worlds would be to have a dedicated machine with a RAID array, where all your machines are dumped to in toto. Then from the backup server, it would just copy from the partitions to the tape drives locally what data should go onto tapes.

      This provides not just tape protection of critical data, but also protects the ISOs and such as well with a pseudo D2D2T setup.

    Backups should be fully automated and trivially easy. I never did backups for my personal stuff before due to the hassle factor.

    • After putting in a new one and installing OS X, the installer asked if I would like to restore my Time Machine backup. With just a click it restored everything (user accounts, data and applications) exactly as it was before.

      My primary drive dying literally only cost me about four hours of downtime. 20 min to replace the drive (iMac, many Torx screws, first time), about an hour to install the OS, and the rest waiting for a few hundred gigabytes to travel over USB from the backup drive.

I too had trouble with doing backups before I got a macbook pro, and I have lost things due to hard drive failure (nothing extremely important, but things I wish I still had) - even that wasn't enough to make me particularly diligent. I'd try one solution or another, and never end up doing more than one backup because of the hassle.

Sure, I'm perfectly capable of scripting incremental backups using rsync or something, but Time Machine actually does it about as elegantly as I would anyway because it hard-links identical files, so each backup is a full root directory.

    My backup runs every night, using cron, rsync and some shell scripts, based on http://www.mikerubel.org/computers/rsync_snapshots/ [mikerubel.org]. It writes all data on my server (mails, home directories, SVN repositiory, database, ...) to an external disk (eSATA). Hardlinks over 10 file trees for 10 days allow me to restore deleted or modified files for up to 10 days. Average backup time is less than 1 hour after the initial backup (that runs for several hours).

    Workstations and laptops contain the operating systems (can be re-installed from CD/DVD/PXE), files copied from the server (local copies of mails, SVN sandboxes, ...), and some temporary files not worth to be backed up. So, I don't need to backup those machines.

The only place I use files other than from there is on my main desktop at home, which has an external drive holding a Time Machine backup (one update/day so as not to age the drive as fast) and a nightly SuperDuper backup (SuperDuper is utter win). Finally, I have a 4TB RAID6 NAS at home where my non-critical files (ripped DVDs, ripped music) is stored as well as an automatic we

  • Weekly and automatically. The latter is by far the most important part. Designing a system without taking human nature into account gaurantees eventual failure.

  • Since "whenever I remember" is the most popular option, would anyone like a 99-cent app for their smartphone that reminds them to do backups?

    • Wouldn't the built-in alarm system do the job just fine? Still automated systems are far preferable, though checking to make sure they still work from time to time is wise.

  • crashplan.com has a pretty nice piece of software (Win, Mac, Linux) that does a pretty fine job of regular backups to locally available storage or (even better) remote storage on another machine running the software. They make their money trying to sell you space on their remote server farm, but the free features work great getting data from the home to the office and back again or backing up your parents machines onto your machine and your machine to theirs. I think the free version is limited to a daily b

  • I found IdleBackup [idlebackup.nl] a while ago and fell in love with it. It's no longer being actively developed, but it works ok on Win7 x64. I tell it which directories to back up, and it saves copies of any new or updated files to my NAS automatically. My next step is to set up a remote solution with my parents' and/or friends' houses to get offsite backup as well, but this at least protects my important files from anything that could happen to them on my PC.

  • I use Mozy Home. It's about $.17/day for my 50 GB plan with a biennial subscription. Advantages are that even if my house were burnt to cinders, I'd still be able to recover, and most backups are quick, unless I've dumped a few hundred new photos or something. Disadvantages are cost and recovery speed over a slow DSL connection.
  • Only wimps use tape backup: real men just upload their important stuff on ftp, and let the rest of the world mirror it ;) Torvalds, Linus (1996-07-20). Post to linux.dev.kernel newsgroup
  • My main data HD is mirrored, so I back thinks up the moment I change something.

  • Network block devices, RAID1 with "write-mostly" option, an stunnel pipe, and a loopback-device mounte single file on a remote server. :)

    And daily backups to that RAID-1 device using http://backuppc.sourceforge.net/ [sourceforge.net].

  • Meh, missing option : Continuously.

    Everything is mirrored. The mirror has a snapshot every hour on the hour. The snapshots are ALL backed up to external drives.

  • Since I reformat or re-install hardware relatively often, I don't have any fancy scripted backup software.

    About once a month, I fire up Ztree (modern Xtree) and I expand the branches of about 5 different important folders, I tag all the files and copy them to an ESATA drive. It's about 150gb of stuff which I class as important.

    When it's finished, I then copy that to another external drive and basically have 2 backups. 1TB / 2TB USB or ESATA drives are very cheap, it's worth it.

    I do actually run an Acroni

  • Do things like Dropbox count as backup? I have automatic processes like that running, but a real, thorough backup with offsite copies is a lot rarer...

  • by smash (1351)
    ... via time machine :)
  • by gig (78408)

    Macs backup hourly, automatically, if you just give them access to a backup disk.

    I also backup daily to an offsite service.

  • With btrfs, I'm taking snapshots every 5 minutes and keeping them for 2 hours, and hourly snapshots for 2 days. This was because I noticed that probably half my data recovery needs were because Firefox or Chromium got wedged and lost all my open tabs, so going back to the previous daily was ok, but it was better if I had one more recent than that. Of course, I also rsync off to a remote server daily, but the 5 minute backups solve 99% of my recovery needs.
  • Three people in the house and three laptops. One macbook and two ubuntu machines. My server runs netbsd and has a disk big enough to store our library and all three backups. My backup script runs at 0800 UT every day and usually completes within five minutes or so. I have a separate backup script which uses rsync to copy the entire /home directory tree from the server on to a portable hard disk attached to one of the laptops. The portable disk is usually stored off site.

  • Time Machine and a Drobo are the best combination. Why? Because they work to prevent data corruption and loss of disks.

    Just the other day my iPhoto library got corrupted somehow (765gb of pictures). I rolled back with the Drobo, and now it's fine. If I had a normal backup program the backup would be just as corrupted as the iPhoto library and I'd be SOL. Thanks to Time Machine and 5TB worth of Drobo I only had to deal with 12 hours of restore instead of weeks worth of library reconstruction (I keep backups
