MSDP pool replication

What you want is perfectly possible but as Yashikura says use duplication and not replication

Just add each of the stages you want into Storage Lifecycle policies - based on what you say you need at least 4 SLP's (but bear in mind you may want daily, weekly and monthly versions of those)

As they are all MSDP they will all use optimised de-dupe when they copy data between each other.

You may find you need to give each media server access to the other media server via the storage server credentails section

Hi briggsy,

from what you are saying, having one NetBackup Domain the AIR is not applicable here.

What you need to do is Duplications between two MSDP servers using a secondary operation in an SLP.

note that every duplication between two MSDP's is a Optimised-Duplication, meaning that only the unique data (data segments not yet stored at the destination) is transferred every time.

hope this clears things a bit.

Kind Regards,
