Are you specifying -mpx on your bpduplicate? If you don't, the backups
will be "de-multiplexed" on the copies, which mean it will have to go
through the original tapes several times to pick out each backup image
individually. If you use -mpx, it'll grab all the backup images in one
pass and leave them multiplexed on the copies.
