Ask HN: Any backup software similar to version control?

• modzilla 12y ago
  Apple's Time Machine keeps daily (or more frequent within a given day) snap shots of all of your folders.[1] Also, in any native OSX app each "save" works like a git commit, you can browse all "versions." [2] Combined, these native OSX features do exactly what you want.

    Similar in Linux is Back In Time http://backintime.le-web.org/ http://backintime.le-web.org/

  1.) VEEAM for VMware or Hyper-V does this job. You can access restore points at a specific point of time. 2.) Never saw a file-diff tool implemented in a backup software. You may only have backup logs for your incremental backups about the size, duration, etc. If that's what you meant by view changelogs of a backup file.

    Heh, I don't need file-diff specifically. I just want to see for example this file was last changed on Tuesday, and be able to pull up the Tuesday version.

      This is exactly what you can do with VEEAM. You can even set your backup strategy to continious integration. As soon as one backup up for the virtual machine is done another incremental will be created; with minimal impact on I/O performance. To save backup-disk-space you may want to enable deduplication in VEEAM. When you browse you backups you can choose from the available backups and you can open and browse the complete file system at this specific date and time. You can restore one or more specific files or directories directly back to the origin destination or copy & paste them to a different location on any target. You also can start the entire VM directly from backup at this state in an isolated environment to access the system as a working machine. There are tons and tons of more features inside this backup solution. We run this solution in our office and for most of our customers with virtualized environments. There is even a free version of veeam that lacks datacenter features but you can backup your VMs. Our usual backup intervals between 8a.m. and 9p.m. is 2 hours. We ensure to have about 5 to 8 restore points during work ours. So you will have to choose the Tuesdays version of the file at a specific time. You may want to give it a try if you're running ESXi or Hyper-V.

  Just use Git (sans GitHub) for whatever you're doing. It works quite well on just about any content (although viewing changes/merges is a little more difficult without setting up special mergetools and difftools for special files like images)
  • mushly 12y ago
    Hm, I thought Git doesn't handle versioning of binary blobs so well though?

  I'm not 100% sure because I haven't used it for few years, but BackupPc normally lets you browse the files of a specific backup set but it has also a "history" function for a directory that maybe is what you're looking for: http://backuppc.sourceforge.net/BackupPCBackupBrowse.html http://backuppc.sourceforge.net/BackupPCBackupBrowse.html

  Bup satisfies both. https://github.com/bup/bup https://github.com/bup/bup But the frontend is kinda bare-bones. In many cases, it's git. I have heard that attic is similar but more fleshed-out. But I have not tried it myself. https://github.com/jborg/attic https://github.com/jborg/attic

  Ori FS does replication and atomic snapshotting: http://ori.scs.stanford.edu/ http://ori.scs.stanford.edu/ Some of its underlying architecture is very similar to git. Check out Section 5.4 of the paper: http://delivery.acm.org/10.1145/2530000/2522721/p151-mashtizadeh.pdf http://delivery.acm.org/10.1145/2530000/2522721/p151-mashtiz...
