What's the benefit of Duplicity over Tarsnap http://www.tarsnap.com/ http://www.tarsnap.com/ ? Thanks

  Duplicity is an open source project that can be used with different types of storage (I use them with OpenStack Object Storage instead of S3). You can host your own backups if you want (supports ftp, sftp, ... check the docs: http://duplicity.nongnu.org/duplicity.1.html http://duplicity.nongnu.org/duplicity.1.html), but Tarsnap is an hosted solution.

  I played a bit with both and they both worked well. Tarsnap: easier to set up and use Duplicity: fully open source, and I think the restore speed was significantly faster ... but I've not properly benchmarked it apples-to-apples. If you are backing up a lot of frequently changing files (eg. database backups) then tarsnap's bandwidth charges (probably caused by the underlying EC2 charges) can swamp the storage cost. Running duplicity against rsync.net avoids this.

    restore speed was significantly faster with duplicity? I haven't used tarsnap yet, but one of my main gripes with duplicity is the rather slow restore speed. Is tarsnap even slower?

      Depends. tarsnap restore times should be constant regardless of which backup you pick, since it's just downloading the relevant blocks. duplicity does full backup + diffs, so if your data changes quite a bit you can end up downloading a lot of data that doesn't land on disk. (i believe that's right, not verified.)
