We run VM:Backup to local tapes and HIDRO to remote tapes. HIDRO is much faster and doesn't chew the CPU the way VM:Backup does. But the users are used to getting their stuff out of the much prettier vmbackup interface.
If you twin remotely and locally, how does the restores work? Do you have to code to just use the local drives for that?

VM:Backup has the tape volsers in its catalog. If you don't have the correct volsers at your remote site, you have a problem. You could probably get away with different volsers if you code VM:Backup's tape mount user exit to translate the local volser to the remote volser. VM:Backup will probably want to check the tape label, so you'll need to make sure that was copied as part of your tape copy. You'll need to mount the tapes with BLP at the remote site if you do this. Note: I haven't tested any of this. We run a separate backup job, from a separate VM:Backup service machine, for our DR backups. Dennis O'Brien "Don't worry about biting off more than you can chew.

Not if you do the backup to local tape drives, and then do a tape-to-tape copy to the remote drives. Mark Post
