Considering using rsync on a couple systems for backup, I was wondering if it's possible, and if so how difficult is it, to delete files which have been backed up (in order to save space on the backup media).
Anyone with experience doing this?
it's certainly feasible for a a fairly lackluster backup solution (e.g. gonna rebuild machine, want all of /home saved to other machine, rsync then reinstall to try $new ditro!) but I wouldn't recommend rsync for product grade backups; it'd get very complex very quickly trying to figure a way to do versioning (rsync would be really good for 'oops, I removed X file, but I'd copied it over to M machine, so I can recover', not very good at 'someone changed this file 4 days ago and now it doesn't do what I want, I'd like to go back to a previous version). at least in my estimation.
Urk, insufficient coffee this morning. In my previous reply I thought this was the backuppc list. Backuppc does in fact do a very good job of storing backups in minimal space - and can use rsync to do it while also maintaining versioning so it is great as a generic backup solution. But, it doesn't have anything built-in to delete target files after the copy. There is an option to run post-backup scripts that might work.
alternative: check rsnapshot.
