rsync is designed to work with two random-access file systems, so no, it 
wouldn't be suited for direct to tape backup. You could rsync to a local 
copy, and then spool that to tape, but you've pointed out that you have 
limited disk space and want something that goes direct to tape. In 
addition, you lose most of the performance benefits of rsync if you try 
and use it with a network mounted file system, rather than running the 
rsync protocol over the network.

Seems like a reasonable choice, seeing as you are spooling to tape.
