Creating Volume Snapshots

Describes how to create snapshots of volumes using the Control System and the CLI.

You can create a snapshot manually using the Control System and the CLI, or use a schedule to automate snapshot creation.

Note: The maximum number of snapshots that you can create for each volume is 4092. Exceeding this limit raises the snapshot failure alarm with an appropriate entry in the CLDB logs.

Creating Snapshots of Multiple Volumes Using the Control System

To create snapshots of multiple (standard and/or mirror) volumes manually:

  1. Log in to the Control System and go to the Summary tab in the Data > Volumes page.
    Note: When running on a Kubernetes cluster, the Summary tab is on the Volumes page.
  2. Select the volume(s) for which you need to create the snapshots.
  3. Click Snapshot Volume from the Actions drop-down menu.
    The Snapshot Volume(s) confirmation dialog displays.
  4. Verify the list of volumes and enter a unique name for the snapshot in the New Snapshot Name field.
  5. Click Snapshot Volumes.
