mixed system backups

I can think of a few options that don't require root over the network (they
do need it on the local host), I guess the solution depends upon your
resources and the risks you are willing to take.
Your 1 script requirement does kinda force you into the ssh option however.
Have you thought of doing something like having a backup process (cron job)
run on a PC and drop files into a certain dir.
Then the tape drive can backup that dir nightly (or you could get smarter
and do incremental backups, use rsync,....).

There are existing, network enabled, backup solutions out there, have you
had a look at them? Personally I rolled my own using cron and rsync and
using hdd's (tape wasn't an option, all the machines are in texas and my
arms ain't that long ;).
