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) console.
  2. In the navigation pane, choose Clusters > Dedicated Clusters.
  3. Click the name of a cluster and choose Snapshots.
  4. Click Restore.
  5. 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.
