I use BackupPC too, I've used it to restore files after stupid mistakes
often enough that it's been well worth the effort of getting it set up.

The biggest risk with BackupPC is that it's very vulnerable to a
single-sector failure on the disk. The file that's corrupted will be
corrupted for every machine that has that same file, for all your
backups to the beginning of time.

My secondary backup uses Amanda and DVD-RW. I can't afford real tapes,
I'm interested to see how long the DVD-RWs last before they quit

You can, if you run a second configuration that only does full backups
and only runs on Fridays. Or you can leave the tapes out all week so it
wants to put everything on the Friday tape. Not quite the same thing as
full control over backup schedules though. With Amanda it's best to just
leave the schedules to the planner.
