Maybe it is an option worth investing in. We have to backup a couple of NAS 
boxes on AIX TSM 4.2 Server. There are a couple of million files on the NAS box 
that have to checked during backup. Journaling would be helpful in this 
situation.
The other situation where Journaling would be helpful is support for AIX. We 
have a couple of AIX Servers that have 6-7 million files. The backup is about 
60 GB for those Servers but the backup runs for 10 hours.
Tivoli should seriously think about extending the Journaling support to AIX and 
NAS boxes.
