Managing Snapshots

The snapshots of the data created by the IntelliSnap backup are also available for various other operations like unmount or delete.

Unmount Snapshots

Use the following steps to unmount snapshots.

  1. From the CommCell Browser, navigate to Client Computers| <Client> | File System | defaultBackupSet
  2. Right-click the subclient and then click List Snaps.
  3. Right-click the snapshot you wish to unmount and click Unmount.
  4. To select multiple snapshots, hold <Shift> key and select the snapshots to be mounted.
  5. Click Yes when prompted if you want to continue.

    If the snapshot does not get unmounted, select the Force Unmount option to mark the snapshot as unmounted.

Delete Snapshots

Snapshots can either be deleted using job-based pruning or from the list of displayed snapshots when browsing snapshots. Data Aging can also be used to define the retention rules and pruning of snapshots.

  • Manual deletion of snapshots is not recommended. When a snapshot is deleted, it is no longer possible to perform data recovery operations from the snapshot copy. However, if a backup copy was created from the snapshot, data recovery operations can be performed from the backup copy.
  • Ensure that the snapshot to be deleted is not mounted.

Use the following steps to delete snapshots:

  1. From the CommCell Browser, navigate to Client Computers| <Client> | File System | defaultBackupSet
  2. Right-click the subclient and then click List Snaps.
  3. Right-click the snapshot you wish to delete.

    Ensure all snapshots with the same Job ID are selected for a successful deletion operation.

  4. Click Delete.
  5. Enter the confirmation text string, erase snapshots.
  6. Click OK.

Verification of Configuration Using SnapTest

Validation of the IRM configuration prior to running production jobs can be done through the SnapTest utility. This tool is located in the Base folder of the Software Installation directory, which allows to check array connectivity and exercise the hardware snap engine to create and remove snapshots. Running this prior to productions routines will validate the configuration is properly defined on the Production Host side. See SnapTest tool for step-by-step instruction on how to run the tool.
