Hi there,
I've been searching on this forum and reading redbook sg246844 to learn and setup DRM on our TSM server, but i've still some doubts hopefully you can answer.
From what i can understand:
1. The rotation/expiration on DRM tapes will be exactly the same as in your primary pool, since files use Mgmtclass retention. That is, i cannot use a different rotation for my DRM than i use for my daily.
2. If i want to have daily database backup and weekly DRM tape rotation, every monday i'll get 7 database tapes (!!) no matter what i do, being my only choice lowering the drmdbbackupexpiredays
The thing is, we have daily backup, then copy to a copypool. We want to add DRM on a weekly basis, the usual standard "i backup my primary pool to drmpool (thankfully only one tape!), backup my database and take it out", and wait for a month until reuse those tapes again.
The problem is our retention policy in our primary pool is 15 days, and i dont quite grasp how to play with reusedelay (i'd guess 15 days more?), and database settings...
I was thinking that i could do only weekly db backup to tape and daily to HD, but i don't know if drbdbbackupexpiredays would rotate those backups (and i wouldn't be able to use del volhist weekly without affecting drm..)
Hope it makes any sense, and thanks in advance for the replies!
