rdiff-backup[1]. I don't know what your NAS is, whether it's an off-the-shelf thing or a DIY system, but I tend to initiate the backups on my NAS (which is a Debian-powered mini itx PC). You can initiate from the clients instead if you prefer. rdiff-backup is, conceptually, quite similar to the level of detail you are working at with your script, so it should be easy to get working. I'd also consider looking at Obnam[2], and I'd avoid rsnapshot if I were you (it falls over with large quantities of files, such as mailboxes, and rdiff-backup basically does the same job but better). rsync, whilst an awesome piece of software, is not, on its own, a backup system. When evaluating or building a backup system, consider all of the points in "The Tao of Backup"[3]. Finally, remember that RAID is not backup[4]. (JWZ's advice about a 3rd backup disk here is particularly good. I presently use rsync for my 3rd backup drive.) Penultimately, I'll echo what another poster has said, backuppc[5] is very good, especially if you have windows clients (I realise you don't), although the backend storage (last time I looked) was a somewhat awkward format that I think would be painful to extract stuff from in an emergency situation should the BackupPC software itself fail. As for Bacula, I *think* it's more geared towards an enterprise-level, perhaps using tape backups, like Amanda. I know you can use Bacula w/o tapes (Amanda too) but that's kind-of where it came from and it still "feels" like a tape-oriented system to me (others are welcome to jump to Bacula's defence here) Finally, and although Tao of Backup covers this I'll repeat it: test restores. Test how easy restores are for any tool of choice. Restores, restore performance and restore UI is infinitely more important than the backup process.
