Vault tape rotation

Hello,

We are using Netbackup Vault to eject media for the library. We want to rotate tapes in and out of the library for DR purposes. I have read in the documentation that you have a vault policy to do this, however I have not been able to get it to work. 

Currently is eject tapes everyday which have been written in the last 7 days.

I had to write a bash script to be able to check for tapes that are not full and have been mounted more then 7days ago. However I really think there is way for vault to do this. 

Any ideas?
