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
- Log in to the GaussDB(DWS) console.
- In the navigation pane, choose Clusters > Dedicated Clusters.
- Click the name of a cluster and choose Snapshots.
- Click Restore.
- 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.
