Think about the need for this (off-siting tape backups of log files).

How often do you need the logs? How often during the day do you back
them up? How often have you had media failure that requires using the
copy pool copies? After thinking these through, how important *is* it
to offsite log files?

I understand the administrator's desire to offsite 'em, but is there a
viable business case for electronic offsiting? If there's a tape drive
or tape volume bottleneck in conjunction with the redo log backups,
there is probably a need to review the resources you currently have,
with a thought toward increasing those resources.
