I'd look at backuppc first - running on a different machine which can
be fairly low-powered or one that does something else in the daytime.
It pools multiple copies of identical content with hardlinks so you
can keep much more history online than you would expect, and it
provides a nice web interface for browsing backups and doing restores.
 And it basically takes care of itself.

Tapes are really inconvenient compared to online backups and disks are
so inexpensive these days that tape only makes sense for archiving.
