Taking a Snapshot (VAST Web UI)

Snapshots can be scheduled using protection policies. This procedure creates a single snapshot.

  1. From the left navigation menu, select Data Protection and then Snapshots. 

  2. Click Create Snapshot.

  3. Complete the fields:

    Field

    Description

    Name (required)

    Enter a name for the snapshot.

    Path (required)

    Enter the path to a directory. The snapshot will include all files and folders under the specified directory at the time of taking the snapshot.

    Expiration time

    If you want to make sure the snapshot expires some time in the future, specify that time here.

  4. Click Create.

    The snapshot is created and is listed on the Snapshots page.

Viewing Snapshots

In the left navigation menu, select Data Protection and then Snapshots.

The following information is displayed for each snapshot:

Field

Description

Created

The time the snapshot was created.

Name

The name of the snapshot.

Locked

Reflects if the snapshot is locked (Yes) or not (No).

Type

Possible values:

  • remote. The snapshot was replicated to the cluster from a native replication peer. A restore point for each remote snapshot can be viewed on the Restore Point tab of the source replication peer's VMS Web UI.

  • local. The snapshot was created on the cluster, due to a local protection policy or a local manual snapshot.

Path

The path that is captured by the snapshot.

Policy

The protection policy that created the snapshot.

Expire

The time the snapshot is scheduled to expire.

Deleting Snapshots (VAST Web UI)

  1. On the Snapshots tab in the Data Protection page, click the Actions_Button.png button to open the Actions menu for the snapshot and select Remove.

  2. Click Yes to confirm the deletion.

Locking and Unlocking Snapshots

Locking a snapshot protects the snapshot from deletion.

A locked snapshot is not deleted by any of the following:

  • Exceeding its expiration time

  • Due to its snapshot policy's retention limit

  • User attempted deletion without first unlocking it

Snapshots are created in an unlocked state.

Locked snapshots count towards the retention limit of their snapshot policy. If the number of locked snapshots that were created by a given snapshot policy is equal to the retention limit, the snapshot policy stops taking new snapshots.

  1. On the Snapshots tab of the Data Protection page, find the snapshot you want to lock.

    The Locked column shows whether each snapshot is locked or not.

  2. Click the Actions_Button.png button to open the Actions menu for the snapshot and select Lock or Unlock as needed.
