  • Migrating to new Media agent
    Posted: 03-21-2019, 12:20 AM

    Hope someone can advise on the migrating to a new media agent.

    is it possible to create a new storage policy with a new deduplication policy instead of migrating the old one?

    The plan is to move the servers backup to the new storage policy + new deduplication policy and let the old one age naturally and later delete the old storage policy and deduplication policy


    However will there be any issue to restore tapes that backup through the AUX copy under the old storage policy.

    Hi AnthonyTeah

    Base on the description of your environment, here are your options:

    • Option 1 - provision a new New MediaAgent (DDB) and create a new Storage Policy 
      • Point all your Primary Backup to this new Storage Policy
      • Let the Data Age out as they meet retention on the old Storage Policy 
      • However as you have mentioned you have a long term Tape Copy, you will not be able to delete the Storage Policy until the data has met retention
    • Option 2 - provision a new New MediaAgent (DDB) and create a new Copy within the Old Storage Policy
      • Promote the new Copy (with new MediaAgent) as the Primary and start writing backup to the new copy
      • Disable the old Primary Copy and allow it age out naturally
      • Once the Data is all aged out, seal the old DDB and delete the old Copy.
    • Option 3 - provision a new New MediaAgent (DDB) and create a new Copy within the Old Storage Policy (as well as Aux Copy the data)
      • Aux Copy all the Data from the old MediaAgent to the new MediaAgent
      • Promote the new Copy (with new MediaAgent) as the Primary and start writing backup to the new copy
      • Disable the old Primary Copy and allow it age out naturally
      • Once the Data is all aged out, seal the old DDB and delete the old Copy.
     
    With option 2 & 3 this will allow you to retain your Tape data, and will also simplify your migration to the new MediaAgent. Additionally you will only need to maintain one Storage Policy rather then two. 
     
    Hopefully that helps
     
    Kind Regards

    hi Winston,

      Thx a million for your answer.

      For the option 1,  if the storage and global deduplication policy had been deleted, is it still possible recover the data from the full tape backup?

     

    Regards

    Anthony

    Hi Anthony 

    If you are to go with Option 1, the old Storage Policy will need to be retained (Copy for the Tape) so you can retore from Tape, but you can safely remove the old Primary Copy, along with the DDB, Storage and MediaAgent. 

    As long you retain the Copy to Tape and a MediaAgent is connected upto the Tape Library, when you restore CommVault will be aware of which back job resides on which tape.

    Regards
