Manual Replication (AIR)

We have two domains, both using Data domains. Currently , replication(AIR) isn't setup between the domains.

we are planning to decommission one domain, but before doing so, we want to replicate(through AIR) some long term backup images to other domain for future restore purposes.

  1. Is it possible to configure the replication ( through AIR) between two domains now( using Data domains)and manually replicate the existing backup images from one domain to another?
  2. If yes, would restore be possible from the second domain after the first domain is decommissioned?.

Thanks!!

    It is doable, but it will involve some trial and error since the procedure is not documented.

    The first step is to establish and test AIR replication between the two domains. Use the same name for both SLPs. Once you successfully perform a test backup and confirm that replication is working, you can proceed to the next steps.

    You will need to run the nbreplicate command. Some testing will be required to determine which options you need to use.

    The most basic command is:
    nbreplicate -backupid <backupid> -cn <backup_copy_no> -rcn 101 -slp_name <slp_name>

    You may need to experiment with the rcn value (for example, 102) and possibly add the -target_sts option, depending on the results.

      Thanks!!

      Let me share an example to explain the scenario and get your guidance

      We have two Netbackup master servers

      1. NBU master server 1 ---> using Data domain A
      2. NBU master server 2 ---> Using Data domain B

      Both Data domains are located on different Data centers..

      The backup flow is as follows:

      1. The first copy from both master server is written to data domain A
      2. Then duplicated to Data domain B

       

      Given this setup, what would be the recommended way to proceed further..

    Hey

    I think this will not suit you, but just for a reference - now in NBU 11.1 there is a possibility to replicate backups to the other domain from WEBUI, check out the release notes for 11.1

    Cross-Domain Backup Replication Support

    https://www.veritas.com/content/support/en_US/doc/103228346-170351487-0/v171086204-170351487

    There are other nice features, like:

    • Support to create instant access VM feature for Nutanix AHV
    • Support for Kernel-based Virtual Machine (KVM)
    • MSDP server evacuation in NetBackup
    • Cloud parallel stream job hierarchy for Cloud VM backups
    • Freeze mode in NetBackup
    • Cross-Hypervisor Restore from VMware to Nutanix
