Viewing Snapshots of a GaussDB(DWS) Cluster
This section describes how to view snapshot information on the Snapshots page.
Viewing Snapshot Information
- Log in to the DWS console.
- In the navigation pane on the left, choose Dedicated Clusters > Management > Snapshots. In the snapshot list, all snapshots are displayed by default.
- You can view the Snapshot Name, Snapshot Status, Cluster Name, Backup Mode, Snapshot Type, Storage Media, Snapshot Level, and creation time of snapshots.
You can also enter a snapshot name or cluster name in the upper right corner of the snapshot list and click
to search for the specified snapshot. GaussDB(DWS) supports fuzzy search.
