Set resourceutilization in the client's configuration to twice the
number of streams you want to run. If anything is likely to go directly
to a sequential stgpool, set your maxnummp for the node definition to at
least the number of streams you want to run (make sure you aren't going
to hurt other clients more than you're willing to).
I'd recommend that you set up the journaling daemon too. It takes a
tiny bit of system resource, but in doing so, it spreads out the process
of scanning the system from all at once during the backup, to just
monitoring the changes as they're made (after your first full backup).

Subject: [ADSM-L] Several simultaneous backups of an AIX client
Hello everyone,
I have a situation with an AIX TSM client which is at the 5.5.0.6
release
on a TSM server which is on AIX and is at 5.5.1.1. The client has 18
million files to inspect when doing a daily incremental backup that
begins
at 9PM and as you can see below took almost 11 hours. As you can guess
this just isn't acceptable to run for this long period of time. Does
anyone have any suggestions on what could be done in order to get this
server backed up incrementally in a quicker fashion? Any suggestions
are
greatly appreciated!
