Re: BACKUP DB need a least 2 Tapes?

Werner,

    It sounds to be like you have a 7337 15 slot DLT changer???.

Regardless ... you can checkout the DB tape from the changer/robot without
deleting it from VOLHIST.  And then put a new scratch in for use.
Setup a procedure where your operators can perform this every day at the
appropriate time ... ????

cheers ... joe.f.
P.S>  if you do have a 7337 why are you not using all 15 slots?  Don't
waste one on the clean cartridge just have OPS do that too!
