PolarDB：Backup method 1: Automatic backup

Note

• The backup files that are automatically created cannot be deleted. You can configure the retention period of automatic backup files in the Data Backup Retention Period section in the Backup Settings dialog box.
• 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.
