Hi,

 

I am going to change my current storage with the new one, so i want to move my deduplication data to the new storage(new storage mount point).

Media server is on RHEL 6.1

Netbackup version 7.6.0.3

My question is how we can move the Dedupe storage to new storage mount point without affecting the consistency of dedupe database.

- Do we need to take any other precautions during this migration process.
Take care that NBU is offline and that all processes on media servers have stopped.
Take care that new volume is mounted to original path.

- Will the data consistent after copy paste.
I thought you were using rsync, not copy paste? 
Confirm at OS-level that folder sizes and permissions are identical after the copy.
There should be no issue with data consistency if NBU is offline during migration.

- Is there any rollback plan for this.
Keep old volume until you are sure that all is okay on new volume.
Your original volume is your rollback.

Why would you want to change the mount point. The whole point of a mount point is that it is a gateway to a storage location, and that storage location can be anywhere. If you're chaning the storage then do so, but keep the same mount point. Simply move the data from old to new with copy or mirror.

Migration to new storage will be best with mirror. If not possible, take NBU down, copy data between moutpoints with utility that will ensure same permissions and other attributes, unmount both and mount new storage to original mount point. If you have Storage Foundation on media server, migration via mirroring and volume grow can be done with everything online. NBU will just be restarted to see new size. Expanding dedupe storage is covered in NBU Dedupe manual.

I am with Marianne.

Migrate to new storage using mirroring.

What volume manager do you use - LVM ?

Hi,

 

Thanks for the reply, we are doing copy paste as Marriane suggested using "rsync" command in Linux.

- Is there any rollback plan for this.

Also we are not using SF in Media server.
