Tape ejects out issue

...BE will not expire sections of a tape...it could do this with disk, but not tape as that is written sequentially. So you are correct in assuming that the tape fills up, and then asks for a new tape to be inserted after ejecting the current tape. No way around this. I know that ARCserve is the same, whilst IBM TSM expires sections of tape (but that's another story completely!)...

Set the Append period lower (say 5 days) and see if this allows the tape to be overwritten.

the other option is to buy more tapes...although not always possible due to finances, this would allow you to keep multiple separate copies, and maintain them for a longer period.

If you want to use only 1 tape, continue to set the Append period lower until it allows the tape to be overwritten when you want it to be!

Thanks!

No.  If you have exceeded the 1 hr. protection period, the tape would be overwritten.  This is why it is bad practice to set such a short OPP.  In fact, you get a warning when you set the OPP to 1 hour.
