The way we currently do backups is to use rsync from the clients to two folders on an older server that rolls over every other week. This worked fine for a while, but the rsync is cumulative and the users generate a tremendous amount of data...

You might want to check out the rsync switches --backup-dir and --suffix. Using them some thing like this:
--delete --backup --backup-dir=$MIRROR_DIR/RsyncBckups --suffix=".$DATE"
allows you to keep an exact duplication of the original directory and keeping the original files that were either deleted or overwritten in a seperate backup directory with dated suffixes, which can be archived on some regular basis. This should allow you to keep the simplicity of rsync and control the cumulative size.
