Data Backup

Data in DWS can be backed up and restored using snapshots. A snapshot is a full and incremental backup of a DWS cluster at a specific point in time. It records the current database data and cluster information, including the number of nodes, node specifications, and database administrator name. DWS allows you to manually create snapshots on the management console. It can also automatically create snapshots as scheduled to prevent data loss.

Currently, DWS supports backup and restoration based on OBS. For details, see Snapshot Overview.
