[OpenAFS] AFS backups and TSM

[Andrew Bacchi]

Hi Joseph,

We've been using TSM and AFS for years with very good results.  I am 
aware of the lack of support from IBM for the future.  Our solution is 
to do AFS butc/backup to disk first, for a complete semester, and then 
move those backup file sets to TSM using a standard TSM client. 

I've had some problem getting the AFS backup to work on Linux, but I 
should have things worked out fairly soon.  I hope to have the new 
system running by the beginning of the fall semester.

I hope this helps, and good luck.
