Backup and Restoration Overview¶
You can back up index data in clusters. If data loss occurs or you want to retrieve data of a specified duration, you can restore the index data. Index backup is implemented by creating cluster snapshots. When creating a backup for the first time, you are advised to back up data of all indexes.
Managing Automatic Snapshot Creation: Snapshots are automatically created at a specified time each day according to the rules you create. You can enable or disable the automatic snapshot creation function and set the automatic snapshot creation policy.
Manually Creating a Snapshot: You can manually create a snapshot at any time to back up all data or data of specified indexes.
Restoring Data: You can use existing snapshots to restore the backup index data to a specified cluster.
Deleting a Snapshot: Delete snapshots you do not require and release resources.
