I would investigate journal based backups for AIX.

Subject: Slow client backup

Hi Everyone,

I am looking for suggestions on how to improve the backup of an AIX TSM client:


                     Node Name: CHRS141

                      Platform: AIX

               Client OS Level: 5.3

                Client Version: Version 5, release 5, level 2.0

            Policy Domain Name: AIX

To a TSM AIX server at the 5.5.5.0 release.

It appears that it is examining over 15 million files which to me is most 
likely the root cause of the backup taking so long.  Is there anything that can 
be done to make this backup run faster/more efficiently?

Please let me know.  Any suggestions are greatly appreciated!  Thanks!
