forgive my nievness, and also for top posting - as Ive lost the OP - seeing as someones raised the issue of backup ideas and tips - is there anything fundamentally wrong with rsync to another (either local or remote location)?
Well, there might be one issue, IMHO - what happens if you're backing up a huge mailbox (say over 1GB) and a message from the beginning gets deleted)?
This is why I love LVM - snapshots...
Snapshots don't solve the problem of inconsistent files, they just shrink the timing window when the copy appears - and if you are using LVM2 , snapshots only recently started working. Then you have the problem of restoring an old message without clobbering current ones if they are all in the same file. Maildir format makes most of these issues go away and you can use something simple like backuppc (http://backuppc.sourceforge.net/) to manage online rsync-based backups.
