What are you trying to accomplish with that? Are you saying that you want two different copies of your 'present' data? It looks like you are already running daily backups, so what about:
Create two pools, with a volume retention period of two months. Run two full backups each day. That will give you two copies of almost identical data. If you are already going to be running daily backups, there isn't a need to run daily differentials and so on. If tape capacity is an issue, run 2 monthy fulls and daily differentials, or weekly fulls and daily differentials, and so on. However, daily fulls and daily incrementals and daily differentials sounds overy complex to me. -Jason Martin -- I distinctly remember forgetting that. This message is PGP/MIME signed.
