If you are backing up a few gigabytes and it is taking 12 hours, then
ext3 is not your problem.  It may be slower than some of the other
options, but it is not THAT much slower.  My largest backup is 300GB and
a full backup takes 15 hours.  Both the client and server are running ext3.

How much memory do you have on the backup server?  What backup method
are you using?
