I've been successfully restoring at DR using TSM for two years. The TSM db
recovery of your size should take only about 15 minutes. Check how long its
taking to back it up, it should take just a little longer to recover if you
have the same hardware.
You really don't restore the tape storage pools just bring you copy storage
pools to the test.
I too see the same problems you see though. My clients are complaining that
we have to vault so many tapes because we keep all the versions for DR
also.
I wish there was a way to tell DRM to only keep maybe 3 of the latest
versions of my on-site pools.
Its one of my projects this year to find a way to do Disaster Recovery
using less tape. maybe backupsets is the answer.

Subject:  Disaster Recovery...Has anyone really successfully done testing?


Good Morning All....

We are running TSM on OS/390 (Version 4.1.4).  We have approximately 200
NT/UNIX/NETWARE servers and are backing our daily incremental stgpools
to copypools for offsite storage.

It appears the copypools don't just keep the active versions of data,
they keep everything....we currently have 190+  Storage Tek 9840s
offsite for TSM.  If we go to the hotsite to do Disaster Recovery
Testing, how do we restore these storage pools in a reasonable amount of
time?  Has anyone successfully performed Disaster Recovery?

Our TSM database is 10GB so, I'm also guessing it will take quite a
while to get that restored???  Any ideas, thoughts?

Is anyone using Backupsets instead of copypools for DR?

Thanks!!
