Mhhh ... I think a DDS3 drive writes 1.2MB/s (2.4 compresses) to a tape
that is 12G (24G compressed). A streaming write of the whole tape should
take less than 3 hours.
Unless I have the wrong data this indicates that your xfsdump is not streaming.
( Do you head the tape stopping,rewinding a bit, starting ..?)
It would probably be worthwhile to play with the tape buffering values and
to research dd like programs with deep buffers.
Since DDS tapes survive only a really small number of head-passes streaming also
helps preserving them.

If you need to buy a tape drive look for DDS alternatives - they are a bit
more expensive - but a lot more reliable,faster and have decent capacities (DLT,..)
