I would second Allen's opinion about your manager (if you dare you can
show him both responses) - beat him with all the manuals on the head until
it opens to different opinions.
I would understand requirement to keep offsite copies longer than onsite
ones but hard to see good business reason for the opposite.
However it could be done quick and dirty:
- define separate primary pool for that data
- backup the pool to separate copypool
- on the seventh day simply delete volumes with discard=yes (and ask your
manager to keep track which volumes have to be deleted and retrieved back
onsite !!!)

Subject: Creating two tape copies offsite with each has Different
Retention
Hello Fellow TSMERs,
This is quite a wild idea but I just would like to solicit your opinions
if
how could I satisfy the the requiremetn asked by manager. He wants in one
backup instance to create two copies for the two copy storage pools one
for
onsite and one for OFFSITE. I know this can be done in TSM 5.1. Aside
from this he added that each of this shoudl have different retentions.
Say, onsite is 15 days retention and offsite is only 7 days. I tried
reading the technical manual of TSM 5.1 but I think it's impossible to do
this unless I will apply the concept of backup set. I don't think the
new features of TSM 5.1 inlcudes this. What do you think, gurus?
If I used the backupset, does anybody of you have experience on this? How
does the backupset performance behaves in the new TSM 5.1?
Any ideas are greatly appreciated.
Thanks,
Edgardo Moso
