Backup Exec 12.5 Changes Media Pool Assignment Automatically

Tim_H1

Hi,

I am running Backup Exec 12.5 on a Windows 2008 Server. I use two media pools; "Onsite" and "Offsite". Occasionally during backup jobs, Backup Exec will move a tape from "Onsite" to "Offsite" or vice versa, enabling it to put a backup job on a tape from the wrong pool. Sometimes it seems like this is done because there are only writable tapes in the other media pool, but this is not always the case.

Regardless of why it is moving tapes from one pool to another, I would like Backup Exec to pause or error out rather than re-assign tapes to the other media pool. How do I make it do this?

Thanks for any help!

...no way to do this as far as I know. It would use a tape for either of the pools if it was available to be overwritten, which shouldn't be too much of a hassle.

If you require that a specific tape stay in a specific media set, then consider partitioning your autoloader/library and targetting jobs at those partitions.

Thanks!

BE will only fetch an overwritable tape from another media set when there is no overwritable tape in the targeted media set.  This is a good thing because otherwise your job would fail due to the lack of overwritable tape.

See this document on how BE searches for overwritable media

If you use partitions to prevent BE from fetching tapes from another media set, then be prepared for a lot more job failures due to a lack of overwritable tape, even though there are overwritable tapes in the other partition.

BE will not fetch an overwritable tape from another media set if there are sufficient overwritable tapes in the targeted media set BEFORE the start of the job.  Hence, the key to solving your problem is to change your OPP such that there are sufficient overwritable tapes before the start of the job.  See this document for a better understanding of OPP and AP

Thanks for the replies! I went the partitioning route, which for us is very simple and quick to set up.
