A backup policy contains configuration items of a backup schedule, such as the backup method, storage method, backup frequency, backup cycle, and backup start time. To facilitate configuration, you can use one backup policy for backup schedules that use the same backup method. This topic describes how to create, modify, clone, and delete a backup policy.

Log on to the Database Backup console

  1. Log on to the DBS console.
  2. In the left-side navigation pane, click Backup strategies.

Create a backup policy

  1. Log on to the Database Backup console.
  2. In the upper-right corner of the Backup strategy list page, click Add backup strategy.
  3. In the Add backup strategy dialog box, configure the following parameters.
    Create a backup policy
    Table 1. Backup policy parameters
    Parameter Description
    Policy Name The name of the policy. We recommend that you set a descriptive name that makes it easy to identify.
    Backup Mode The backup method. You can select Logical Backup or Physical Backup.
    Note
    • After you create a backup policy, you cannot change its backup method. For more information, see Backup methods.
    • If you select Physical Backup, you must set Transaction Log backup interval.
    Full-scale Backup Frequency The frequency of the backup schedule. You can select Periodic Backup or Single Backup.
    Note If you select Periodic Backup, you must set the Full Data Backup Recurrence and Full Data Backup Start At parameters.
    Full Data Backup Recurrence The frequency of the full backup. You can select one or more days of the week.
    Full Data Backup Start At The start time of the backup. You can select a time from the drop-down list.
    Note If the previous full data backup is not finished at the start time of the next backup, DBS skips the next backup.
    Transaction Log backup interval The interval for incremental physical backups. You can specify an interval. Unit: minutes.
    Storage Encryption The method used to encrypt the stored data. Valid values:
    • Non-encrypted.
    • Encrypted: When the system performs a backup task, the system encrypts and stores the backup files. When you download or restore the backup files, the system decrypts and returns the backup files. For more information, see Server-side encryption.
    Note After you create a backup policy, you cannot change its storage method even if in the corresponding backup schedule.
    Delete After The retention period of the full backup data. You can specify a retention period. Unit: days.
  4. Click OK.

Modify and apply a backup policy

  3. On the Backup strategy details page, click the Edit icon icon to the right of Modify backup strategy.
  4. Modify the values of configuration items and select one or more backup schedules to which you want to apply the modified backup policy. Then, click Save.
    Modify backup policy
    Note
    • The modified configuration items are applied only to the backup schedules that you selected.
    • If you click Save but do not select any backup schedules, the configuration items are modified but not applied to any backup schedules.
    • If you modify a backup policy in a specific backup schedule, the modification does not affect the backup policy template.

  2. On the Backup strategy list page, find the backup policy that you want to clone and choose More > Clone in the Actions column.
