Manual backups are backups triggered by you. You can manually back up data at any time based on your business requirements to ensure data reliability. This topic describes how to configure the manual backup settings.


  • You can manually create up to three backups for a cluster.
  • Manual backup files can be deleted.
  • If you modify data after snapshots of your cluster are created, the amount of snapshot backups increases. As a result, the backup cost increases. If data is modified during defragmentation, the amount of snapshot backups increases.
    For example, if your database has 100 GB of data and you modify 10 GB of the data after a snapshot is created,
    • you are charged for 100 GB of data storage and 10 GB of snapshot storage.
    • If you choose to retain the snapshots when you delete your database, you are charged for 100 GB of snapshot storage.
