Performing an Auxiliary Copy

You can perform an auxiliary copy operation to replicate the data from the primary copy to a secondary copy. Auxiliary copy can be performed between any two MediaAgents, regardless of their operating system.

Before You Begin

  • Ensure that the storage policy on which the auxiliary copy operation is planned is associated with a subclient and client backups have been run.

    For more information on how to run backups, see the documentation for the specific agent.

  • You can view the list of backup jobs that are associated with a storage policy copy.

    For more information, see Viewing Jobs Associated with a Storage Policy Copy.

Procedure

  1. From the CommCell Browser, expand Policies > Storage Policies.
  2. Right-click the appropriate storage policy, point to All Tasks > Run Auxiliary Copy.

    Optionally: From the Select Source MediaAgent list, if the source copy is configured with a shared library, you can select the source MediaAgent that is being used for creating a primary copy.

  3. By default, All Copies option is selected to copy data from the source copy to all secondary copies.

    Select the Select A Copy, and then from the list select a secondary copy.

  4. Optional: Enhance the performance of the auxiliary copy operation:
    • To enhance the scalability of the auxiliary copy operation and for load-balancing between the CommServe and the MediaAgent resources, ensure that Use Scalable Resource Allocation check box is selected.

      Notes:

      • The operation window for auxiliary copy can now be enabled on the MediaAgent or the client level and it is honored when the Use Scalable Resource Allocation option is enabled. However, the operation window might not be honored and the auxiliary copy operation might still run, if the CommCell Console from where the operation window is enabled on the MediaAgent and the CommServe are in different time zones.

        For more information, see Operation Window Overview.

      • The CommServe and the MediaAgent resources will not be optimally utilized in the following conditions:
        • When running the auxiliary copy operation for NAS data
        • When the MediaAgents are not upgraded to the latest SnapProtect version
    • To enhance the auxiliary copy performance by copying only those backups that were successfully verified in the data verification job, ensure that the Skip jobs that failed data verification check box is selected.

      For a detailed description, see Auxiliary Copy Job Options.

  5. On the Job initiation tab, define whether the auxiliary copy job runs immediately or if it will be scheduled.

    For more information, see Job Initiation.

  6. Optional: Set advanced auxiliary copy job options, click Advanced.

    For more information, see Advanced Auxiliary Copy Job Options.

  7. Click OK.

    Note: If an Install Updates job or a CommServe service restart is performed when an auxiliary copy job is running, then after the completion of the Install Updates job or service restart, the auxiliary copy job automatically picks up the new backup jobs available on the source copy.

Result

After your auxiliary copy operation is complete, you can view the auxiliary copy job history. For more information, see Viewing Auxiliary Copy Job History.
