Can I Recover Deleted Data of a DCS Instance?
If you have backed up the DCS instance, you can restore its data from the backup. However, the restoration will overwrite the data written in before the restoration.
You can restore backup data to a master/standby, cluster, or read/write splitting instance through Backups & Restorations on the DCS console. For details, see Restoring a DCS Instance.
If a DCS instance is deleted, the instance data and its backup will also be deleted. Before deleting an instance, you can download the backup files of the instance for permanent local storage and can also migrate them to a new instance if you need to restore the data. For details about how to download the backup data, see How Do I Export DCS Redis Instance Data?
