Restoring a Snapshot to the Original Cluster

Scenario

You can use a snapshot to restore data to the original cluster. This function is used when a cluster is faulty or data needs to be rolled back to a specified snapshot version.

  • This function is supported only by clusters of version 8.1.3.200 or later.
  • Snapshots whose backup device is OBS can be backed up.
  • Only a snapshot in the Available state can be used for restoration.
  • Logical clusters and resource pools cannot be restored to the current cluster.

Procedure

  1. Log in to the GaussDB(DWS) management console.
  2. In the navigation pane, choose Snapshots. All snapshots are displayed by default.
  3. In the snapshot list, locate the row that contains the target snapshot and click Restore in the Operation column. The Restore Snapshot to New Cluster page is displayed.
  4. Restore the snapshot to the current cluster.

    If you use a snapshot to restore data to the original cluster, the cluster will be unavailable during the restoration.
