In our DR procedure we have included only the last 8 days of our COPY_POOL volumes from DRMEDIA table, that need to be sent to DR Site. Our backup size is almost 2Tb on a daily basis and we do full backups weekly and incremental on a daily basis to LTO1. Using this method we can control the number of volumes that need to be sent to our DR center, and we can reduce operations during recover, otherwise we need to load required volumes into the library each time TSM require.
We send prepare file and "priority volumes" (from drmedia table) to our DR site and to our offsite safe. You'll not need to change anything in you prepare file, DR plan and DR tests. The result in a DR Test scenario should be the same as your DR Plan. You shouldn't create DR scenario tests that are different from your DR Plan otherwise things might not work. The major advantage is to test DR with COPY_POOL, but you only need to transfer part of your COPY_POOL and not all COPY_POOL volumes. Of course for security purposes....

For this system, we create a backupset every day. This system, in case of emergency, can not rely on the restore of a TSM server. With the daily backuset, I can start this most critical system restore first, and then work on TSM, and the next level critical systems. In a rare case that the backupset tape fails, I can then attempt a restore from the restored TSM server. The daily backupset offers us better timing and better safety for this most critical server.

As Mr. Rodriguez mentioned earlier in this thread, using backupsets for DR testing is not DR testing. If you're trying to replicate the conditions that hold in a real disaster, you're not going to have backupsets conveniently up-to-date and ready for you. One other alternative Mr. Choate has is to run MOVE NODEDATA on the nodes to be tested: MOVE NODEDATA <node_name> fromstg=<copy_pool> Note the volume number of the tape that is written to, and check that tape (or tapes) out in preparation for your test. However, as Mr. Rodriguez also mentioned, this too is not a true DR test. -- Mark Stapleton ([EMAIL PROTECTED]) Berbee Information Networks Office 262.521.5627
