You'll find links to a number of items in http://www.linuxquestions.org/bookmarks/tags/backup
. What you choose should depend on the specifics of your installation and your backup needs. I presume since you were looking at Bacula, you are interested in network backup of a number of computers. For that, I would choose Amanda. Look through some of the bookmarks above and then work through the Amanda Quick Start
on their wiki.
One things that is different about Amanda (and which I really like
) is it's planner, which manages the backup cycle. Rather than telling Amanda you want full backups on weekends and incrementals through the week, you set up what things you want backed up, the length of your backup cycle, how many runs, and so on. Then Amanda manages when to do full and incremental backups
. It intermixes them, with full backups of all the different entries distributed across the backup cycle. The result is that your usage of resources is smoothed out. You get an even distribution of tape usage over the backup cycle (say, a week), even demand on network and server resources over the week, etc. There's no huge peak followed by days of very little usage. It also automatically adapts as your disk usage changes.
