• 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.

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.
