Database Backup (DBS) provides the full backup feature for files in Windows and Linux. This feature is secure, stable, and reliable.


A backup gateway is installed on the device where the source instance is deployed. The gateway version is V0.0.88 or later. For more information, see Add a backup gateway.


Geo-redundancyDBS can back up files to a cloud database in a different region. DBS allows you to restore the backup data to the source or a different device.
Multilevel backupDBS can back up files and folders.
Compressed storageDBS supports the LZ4 compression algorithm to reduce the storage costs.

Create a backup schedule

Create a backup schedule. For more information, see Purchase a backup schedule.

Note When you purchase a backup schedule, set the Data Source Type parameter to File and the Backup Method parameter to Physical Backup.

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.
    Configure a physical backup schedule for files
  4. In the Configure Backup Source and Destination step of the Configure Backup Schedule wizard, configure the backup source and destination. Then, click Next in the lower-right corner of the page.
    Configure Backup Source and Destination - file
    N/ASchedule NameThe 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 InformationBackup ModeThe method that is used to back up data. The value is fixed to Physical Backup.
    Instance RegionThe region where the instance that you want to back up is deployed.
    Backup GatewayThe 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 TypeThe type of the database that you want to back up. Default value: File.
    Backup Destination InformationBackup Storage TypeThe type of storage that is used to back up data. Default value: DBS Storage (recommended).
    Storage EncryptionThe 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.
    Edit Backup Objects - file
  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.
    Full-scale Backup FrequencyThe 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 RecurrenceThe days of the week on which DBS runs the backup schedule.
    Start AtThe 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 BackupSpecifies whether to enable incremental backup. Default value: Disable. This parameter cannot be modified.
    Enable compressionSpecifies 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.
    Precheck - file
    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.
