I think in the case of having to run 2 backups jobs I would run one backup job and then run a utility job to copy the 1st set of tapes to the remote set of tapes.

We use CA's VM:BACKUP for file-level backups, and will be using VM:HiDRO to capture the system image. We're curious as to whether any other CA customers are using the synchronous tape "twinning" feature with one local tape unit and one remote. We've been cautioned by our network folks that the response time from the remote tape unit would be quite a limiting factor affecting the speed of a synchronous, twinned backup. Our other option is to simply run two backup jobs, one to the local drive and one to the remote, but that effectively doubles the hit of the backup jobs. Any anecdotes or insight would be most welcome! Mark Llewellyn VM Systems Support Visa, Inc.
