Bill,
I wanted exactly the same thing. Unfortunately, implementing it is quite difficult in
TSM.
* You need to archive to a primary storage pool
* then you need to checkout the tapes from that storage pool manually and send them
offsite. You can't use DRM to keep track of the volumes as DRM only works for copy
pools and db backups
* You need to manually work out which tapes are required for reclamation (see the
query below) and manually request those tapes back onsite for reclamation as necessary
In the end I gave up on this and I did the following:
* I created a second TSM instance on our TSM server for managing archive data only
* I use virtual volumes so the 2nd instance stores its data on the main instance which
has sole control of the tape library
* Instead of archiving data, I use incremental backups on the 2nd instance. I use a
different management class on the 2nd instance (1 year instead of 1 month)
* because I'm using incremental backups to perform 'archiving' only about 20% of data
changes each month and so the 2nd instance uses much less space that doing a regular
monthly archive
* because the space used is so much less (over a year it's about 400% less) I've
created a copy pool for my archive data as well. I can afford to 'waste' the extra
tapes and I get quite a few advantages namely:
* I can manage the 2nd instance copy pool the same way as I manage the main copy pool
* DRM takes care of onsite and offsite tapes
* You can do offsite reclamation - just like a regular copy pool
* The operators don't need to learn any new procedures for managing the archive tapes
* The archive data is always onsite which makes for easier restoring
Finally, here's the query I mentioned above:
tsm: SM040>q scr q_reclaim_preview f=r
/* Script comment */
/* List volumes in stgpool $1 to be reclaimed */
/* if threshold was set to $2% */
/* ============================================*/
/* Script Name: Q_RECLAIM_PREVIEW */
/* Author: Mark Ferraretto */
/* Parameter: storage_pool, threshold */
/* Example: run Q_RECLAIM_PREVIEW C3 50 */
/* ============================================*/
select -
VOLUME_NAME as "$1 pool at $2% reclamation" -
from VOLUMES -
where STGPOOL_NAME = upper('$1') -
and PCT_RECLAIM >= $2 -
order by VOLUME_NAME

Please respond to
ADSM-L
I am wanting to set up new Policy Domains, with respective Management
classes, and respective Backup and Archive Copy Groups. I want my Archives
to go straight to offsite and not be onsite. Anybody got ideas and how to
do it?
Thank You,
