Linux backup software .. that meets unique requirements

There's boxbackup:

http://www.boxbackup.org/

which sounds like it will do what you want.  A friend of mine evaluated it
for cross-basement backup purposes (i.e. you can put a disk in my basement
server if I can put one in yours) a year or so ago and said it looked
promising but was pretty buggy.

YMMV, etc.
