Hi Eric,
You've probably thought of this yourself, but, there is no need to save up all
your backup stg operations until the end of the day. Since they are
"incremental" in nature, you can run the process earlier in the day with only a
short-running catchup before your migrate kicks in. Of course this presumes
that you have sufficient drives to cope with this at some point in the day.
Regards
Steve.

Hi *SM-ers!
I'm currently struggling with the fact that I cannot run a backup stgpool
diskpool and a migrate diskpool (to empty it out for the next client backup
cycle) sequentially no more. Migration would run well into the evening and I
would like it to be ready at 18:00 hours.
I'm thinking about turning on caching for my diskpool. If it works like I
hope, TSM migration empties out the diskpool, but leaving the actual data
behind, so a backup stgpool diskpool uses these cached copies, instead of
mounting all the tapes during a subsequent backup stgpool tapepool. In that
case, I can run migration and backup stgpool at the same time.
Is TSM working like this or will a cached object, once (logically) migrated,
be backed up from tape?
Thank you very much for your reply in advance!
Kindest regards,
Eric van Loon
