Note: I strongly believe that all file systems should be inside of LVM logical volumes where possible. Combine that with LVM snapshots and you can easily mount a read-only copy of the backup target file system, without worrying that you'll damage your backup directory. They're all command-line tools, which makes for easy scripting and execution via the cron command. All of them can work with remote targets over the network or local folders as the backup target. All of them store at least one (or all) backup revisions as regular files in the file system. I have tried DejaDup which is preinstalled on Ubuntu, but I was not able to access backed up files another way than completely restore the backup, which is insufficient.įor the /home folders (and any other user data folders), I suggest going with something simple like rsnapshot, rdiff-backup or rsync w/ hard-links.
