Configure the backup schedule

1. Log on to the DBS console.
2. In the left-side navigation pane, click Backup Schedules. On the Backup Schedules page, select a region in the upper-left corner.
3. On the Backup Schedules page, find the backup schedule that you want to configure and click Configure Backup Schedule in the Actions column.

   Section	Parameter	Description
   N/A	Schedule Name	The name of the backup schedule. DBS generates a backup schedule name. We recommend that you set a descriptive name that is easy to identify. Backup schedule names do not have to be unique.
   Backup Source Information	Backup Mode	The method that is used to back up data. The value is fixed to Physical Backup.
   	Instance Region	The region where the instance that you want to back up is deployed.
   	Backup Gateway	The backup gateway that is installed to back up data. For more information about how to install a backup gateway, see Add a backup gateway.
   	Database Type	The type of the database that you want to back up. Default value: File.
   Backup Destination Information	Backup Storage Type	The type of storage that is used to back up data. Default value: DBS Storage (recommended).
   	Storage Encryption	The method that is used to encrypt the stored data. Valid values: Encrypted: recommended. DBS uses AES-256 to encrypt the stored data. AES-256 is one of the advanced encryption standard ciphers. The server-side encryption feature is used in OSS. When you upload an object to OSS, OSS encrypts and stores the object. When you download the encrypted object from OSS, OSS decrypts the object and returns the decrypted object to you. For more information, see Server-side encryption. Non-encrypted: The backup data is not encrypted.

5. In the Edit Backup Objects step, enter the path of the files to be backed up in the Source file directory object field and click Next.
   
6. In the Configure Backup Time step, set the parameters that are described in the following table and click Next in the lower-right corner of the page.

   Parameter	Description
   Full-scale Backup Frequency	The frequency of the backup schedule. Valid values: Periodic Backup and Single Backup. Note If you select Periodic Backup, you must set the Full Data Backup Recurrence and Start At parameters.
   Full Data Backup Recurrence	The days of the week on which DBS runs the backup schedule.
   Start At	The start time of the backup. Note If a previous full backup is not finished at the start time of the next full backup, DBS skips the next full backup.
   Incremental Backup	Specifies whether to enable incremental backup. Default value: Disable. This parameter cannot be modified.
   Enable compression	Specifies whether to enable file compression. The default compression algorithm is LZ4. Note After you enable file compression, DBS compresses the backup files to reduce storage costs.

7. In the Edit Lifecycle step, configure the lifecycle for a full backup set in the Configure Full Data Backup Lifecycle section.
8. After the preceding configurations are complete, click Precheck in the lower-right corner of the page.
9. If the Precheck Passed message appears, click Start Task.
   
   After data is backed up, you can view the backup schedule or restore the backup data. For more information, see View backup schedules and Restore files.
