I am using bacula to back up my home network (http://www.bacula.org/).
It may at first seem like overkill; it can handle Unix and Windows
clients, tape or disk backup volumes, and keeps a database of which
files were backed up on which volumes in which jobs and when that
happened, but this enables you to recover not only your last backed-up
state of your machines, but the state at any point for which you still
have the backup volumes. Understanding how to set it up is rather
daunting at first, and requires a bit of thought about how often you
want to back up things, when you want to do full, differential and
incremental backups etc. for each machine. The end result is worth it
though, you just let it get on with the job and it'll mail you a summary
when it's done.
I'm backing up to hard disk volumes and then archiving them off to DVD
when I've got enough to fit on a DVD.
