No. rdiff-backup keeps a a backup plus diffs. You can roll back as far as you want just by specifying the age. rdiff-backup --restore-as-of 1D12h /backup/path/to/file will restore file to the version you used 36 hours ago. It is much easier and more flexible than plain rsync, especially if you set it to backup important directories via cron. I have it backup /etc every hour, so even if I did use etc-update -5, I would find it hard to completely screw things up :) Check out the rdiff-backup web site, it gives several examples of how it can be used - http://www.nongnu.org/rdiff-backup/ -- Neil Bothwick As of next week, passwords will be entered in Morse code.
