    dirvish might work well for your needs. It takes daily snapshots using
    rsync, and uses hardlinks for unchanged files, minimizing disk usage.

    Restoring is easy - each snapshot is under a directory named for the date,
    and you just do a basic file copy of what you want to restore.

    Setup dirvish to store backups on a dedicated disk and to never expire
    backups, then replace the disk either periodically or when it gets full.
