We are looking at ways to reduce tape consumption in our 3494 library- which
is being managed by 2 AIX TSM 4.2.2 servers. In general- we want to write
archive data (separate management classes and storage pools) to disk and
then directly to a tape copy pool, and then eject the media out of the
library for long term storage-- without having redundant copies of the
archive data sitting in a primary tape pool.--
Are there any suggestions on how to accomplish this-- since you can only
route disk pools to primary tape pools first? TSM 5.1 allows synchronous
writes to disk/tape/copy pools, but for TSM 4.2 I'm hoping to find a simple
solution--
All feedback is very much appreciated- - John

Subject: BackupSet: Is there an efficient method to generate backupsets
Date: Thu, 12 Dec 2002 17:15:14 +0100
I need help, please:
Can me tell somebody to solve the problem described in the following
example?
---- begin example
assumption: I have 2 backup_versions
time: day_00
The 1st time I create a backupset, all 1000 active backup_versions are
consolidated on tape_01 {bds000.1,bds001.1, ... ,bds999.1}.
time: day_01
Incremental backup creates 10 newer backupversions {bds000.2,bds001.2, ...
,bds009.2}.
time. day_02
I create a 2nd backupset, all 1000 active backup_versions are consolidated
on tape_02 {bds000.2,bds001.2, ... ,bds009.2,bds010.1,bds011.1, ...
bds999.1}.
Question_1:
I suppose, that all 1000 versions on tape_02 are copied from the inventory
of incremental backup_versions. Is this true?
Question_2:
Is it possible to do the following:
copy {bds010.1,bds011.1, ... bds999.1} from tape_01
copy {bds000.2,bds001.2, ... bds009.2} from incremental backup_versions
this would be more efficient in my environment.
---- end example
Thanks everybody who can give me some useful comments
kind regards,
werner
