We have (forever) backed up using VM:Backup "twins" - reading disk once, writing concurrently to separate backup tapes about 3 miles apart (each with it's own volser). We do full file-level backups and critical system DASD physical-backups each Saturday to three 3590 drives in each data center (six spinning MagStar tapes). Over the past few weeks, each Saturday we've backed up about 350G-500G in 5.5-6.25 hours from an VM:Backup running on an olde z800.

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