I'll bump this up for the morning crowd.  The platform I'm testing is 
Linux/OAFS-1.2.13.  Currently we back up to TSM tape from an AIX 
system.  This is not possible to do using Linux, the alternative is to 
back up to disk, then to tape using the TSM client.

Does anyone have any experience with the incrementals not being applied 
to a level 0 restore?  Thanks.
