Creating an Application-Consistent Backup

CBR supports application-consistent backup in addition to crash-consistent backup. Application-consistent backup ensures the consistency of application data by backing up files and disks at the exact same time. It is suitable for backing up ECSs as well as the MySQL or SAP HANA databases running on them.

Constraints

  • Application-consistent backup is currently not supported for cluster applications, such as, MySQL Cluster. It is supported only for applications on standalone servers.
  • You are advised to perform application-consistent backup in off-peak hours.

Procedure

  1. Create a vault for application-consistent backups by referring to Creating a Server Backup Vault. Select Enable for Application-Consistent Backup.
  2. Associate the cloud servers with the created vault. Ensure that the Agent has been installed on the servers.
  3. Create a cloud server backup by referring to Creating a Cloud Server Backup.

    • If an application-consistent backup is created successfully, a blue letter "A" is displayed next to the backup name in the backup list.
    • If an application-consistent backup fails to be created, the system automatically creates a cloud server backup instead and stores the backup in the vault, and a gray letter "A" is displayed next to the backup name in the backup list. You can view the failure cause in the Management Information area on the backup details page.

  4. Return to the cloud server backup page as prompted. If the backup execution fails, rectify the fault based on the failure details shown on the page.

Follow-up Procedure

If data is lost due to virus attacks or database faults, you can restore the data by following instructions in Restoring Data Using a Cloud Server Backup and Using a Backup to Create an Image.
