For part of handling 1 and 3 and configuration files, I'd recommend
getting all your admins in the habit of using rcs. This gives you more
benefits than just backup in case someone makes a goof, such as logging of
who did what and why, ability to see exactly what was changed all the way
back to the first version of the file, etc. Very handy, but one does have
to develop the habit to actually use it.
I've had good luck with amanda as a backup solution, but then you don't
want to rely on tapes. To each his own.
Amanda is moving towards supporting more than just tapes, I don't know
when that support is due, however.
