I want to go the other way...take a directory and make it a drive letter or a 
new filesystem to TSM. Even if I could split this 15million object filespace 
into 3 or more separate filespaces I think I could get a backup done in a 
reasonable time...or even get it done! Right now it just plain doesn't finish. 
Mostly the scheduler service dies and the backup fails.

IMAGE backups aren't an optoin with 3590E drives and "K" media. I would be here 
forever doing the backup and then I couldn't carry all the tapes! :-)

Any ideas or suggestions?? One optoin they are looking at is just replicating 
this volume to another location instead of or in addition to backups (if I can 
get it to run).
