IntelliSnap - Initiating a Vault or Mirror Copy for the NDMP Agent

You can perform an Vault or Mirror copy for NDMP agent to copy snapshots from primary copy to secondary copy.

Before You Begin

Before you begin, check whether you meet the following requirements:

Procedure

  1. From the CommCell Console, expand Policies > Storage Policies.
  2. Right-click the storage_policy and click All Tasks > Run Auxiliary Copy.

    The Auxiliary Copy Job Options dialog box appears.

  3. On the General tab, choose how you want to copy the data.

    For more information about general auxiliary copy job options, see General.

  4. On the Job Initiation tab, define whether the backup job runs immediately or if it will be scheduled.
  5. Click OK.

    When the Vault or Mirror copy of the snapshot is created, you cannot re-copy the same snapshot to the Vault or Mirror destination.

Result

  • You can track the progress of the job from the Job Controller. When the auxiliary copy operation is complete, the snapshots will be accessible from the secondary snapshot copies.

    Note: During auxiliary copy operation, if the source volume appears offline, or source snapshot or volume is detected as deleted for the primary copy, then the auxiliary copy job completes successfully with the following status:

    For the primary copy, if...

    Status of IntelliSnap jobs on the secondary snapshot is displayed as...

    Source volume is offline

    Partial

    Note:

    • If the source volume is detected as offline during auxiliary copy operation, the snapshots on the volume are skipped and retried in subsequent auxiliary copy operations.

      The auxiliary copy operation attempts 10 times and five days on the offline volume. If volume continues to be offline even after all attempts, corresponding snapshots will not be copied to the destination and the status of IntelliSnap jobs on the secondary snapshot copy is marked as Available with missing snaps.

      To change the default retry attempts and the default retry interval, configure the following Media Management Auxiliary Copy Parameters:

    • Retry Count for Snap AuxCopy
    • Retry Time Limit for Snap AuxCopy (in Days)

    Source volume is deleted

    Available with missing snaps

    Source snapshot is deleted

    Available with missing snaps

    Note: If you enabled the Ignore Completed With Errors job option for Extended Retention calculations parameter, then the jobs with the Available with missing snaps status will be considered as completed and will be aged based on the extended retention rules.

    To view whether the snapshot is copied or not, see Viewing Snapshot Details.
