The ApsaraDB for Redis instance is deleted due to misoperation, and you have no backup files on your on-premises machine. In this case, you can attempt to restore data in the ApsaraDB for Redis console by using the automatically saved backup files. You cannot restore data without backup files.
By default, ApsaraDB for Redis automatically backs up data of an ApsaraDB for Redis instance once a day and retains backup files for seven days. You can restore data from the backup files to an ApsaraDB for Redis instance in the console. For more information, see Data restore.
