Contributors netapp-aherbin

Create snapshots of the consistency groups in your ASA r2 storage system to protect the data in the storage units that are part of the consistency group. If you no longer need to protect the data in any of the storage units in the consistency group, you can remove snapshot protection from the consistency group.

If you no longer need to protect the data from specific storage units in the consistency group, you can remove those storage units from the consistency group.

Add snapshot data protection to a consistency group

When you add snapshot data protection to a consistency group, local snapshots of the consistency group are taken at regular intervals based on a pre-defined schedule.

You can use snapshots to restore data that is lost or corrupted.

Steps

  1. In System Manager, select Protection > Consistency groups.

  2. Hover over the consistency group you want to protect.

  3. Select three vertical blue dots; then select Edit.

  4. Under Local protection, select Schedule snapshots.

  5. Select a snapshot policy.

    Accept the default snapshot policy, select an existing policy, or create a new policy.

    Option Steps

    Select an existing snapshot policy

    Select downward pointing blue arrow next to the default policy; then select the existing policy that you want to use.

    Create a new snapshot policy

    1. Select blue plus sign followed by the word add; then enter the new policy name.

    2. Select the policy scope.

    3. Under Schedules select blue plus sign followed by the word add.

    4. Select the name that appears under Schedule name;

      then select blue arrow pointing in downward direction.

    5. Select the policy schedule.

    6. Under Maximum snapshots, enter the maximum number of snapshots that you want to retain of the consistency group.

    7. Optionally, under SnapMirror label enter a SnapMirror label.

    8. Select Save.

  6. Select Save.

What's next

Now that your data is protected with snapshots, you should set up snapshot replication to copy your consistency groups to a geographically remote location for backup and disaster recovery.

Remove snapshot data protection from a consistency group

When you remove snapshot data protection from a consistency group, snapshots are disabled for all the storage units in the consistency group.

Steps

  1. In System Manager, select Protection > Consistency groups.

  2. Hover over the consistency group you want to stop protecting.

  3. Select three vertical blue dots; then select Edit.

  4. Under Local protection, deselect Schedule snapshots.

  5. Select Edit.

Result

Snapshots will not be taken for any of the storage units in the consistency group.
