Database Backup (DBS) allows you to back up and restore ApsaraDB and ECS-hosted databases. You can also download backup sets from the cloud to your local computer to enhance data protection. Backup sets can be downloaded manually or automatically. You can use downloaded backup sets to restore local databases, analyze and audit Excel files, and back up data to local storage.

Features

DBS packages, compresses, and converts backup files to downloadable files. You can download these files manually or automatically by using DBS backup gateways. For more information about specific operations, see Manually download a backup set and Configure automatic download of backup sets.
