Girl and Guys,

lets make it clear - is journal backup feature only available in Windows 
or I am missing something.
If I am not wrong Peter posted in the beginning that is talking about AIX 
boxes, so journaling TSM feature is not available there.

Hi

Upgrading at least the client to a newer level such as 4.2.1.20 or 
4.2.1.30 would be a good idea. The 4.2.1.0 client has had a lot of 
performance problems.

Another thing to use is the journal-based backup, which probably will save 

you a lot of time.

Best Regards
