Fastback II does that (compresses while it backs up).  It gives couple options
something like:  no compression, minimize time (to back up), minimize space
(on backup medium).

It also bunches all your files into one big one (which I prefer) (maybe
optionally leaves them separate?), and works to appleshare server
(including unix machine via gatorbox) -- the only program I could find
that does that correctly, though others try to claim it.  And, it has
a macro capability, including the ability to run macros unattended, so
you can schedule back up in the middle of the night, but you must leave
your machine on (surprise!) and you must leave fastback running.
