Deduplication pool
We have a master server and 3 media server in our enviornment all windows based.
All media servers have a msdp configured (pure disk). On one of the pools we are running out of space.
Can we increase the space of the pool ?
How can we check if cleaning is working properly or not?
How to manually expire images that are old to retain some space?
The max MSDP pool size on Windows is 64 TB.
The NetBackup Deduplication Guide explains under this topic : Resizing the MSDP storage partition how to increase pool size.
In short - stop NBU on media server, use Array and OS tools to increase disk size, start NBU, then Inventory the disk pool in the GUI.MSDP cleanup runs every 12 hours.
You can read in the same manual under this topic: Managing Media Server Deduplication Pools about
Deleting backup images and About the MSDP data removal process.There is another process called 'rebashing'.
Storage is only reclaimed during this process.
See: About MSDP storage rebasingHopefully reading through these topics will answer your questions.
