Creating a BMS Backup
Automatic Backup
After a backup policy is bound to a BMS, the BMS will be periodically backed up based on the backup policy. You can focus on service running rather than whether backups are created.
Manual Backup
If you want to back up BMS data at any time, you can manually create BMS backups.
- On the CSBS console, click Create CSBS Backup in the upper right corner.
- Select a BMS from the server list and select the disks to be backed up.
To ensure post-restoration data consistency, you are advised to back up the entire BMS.
If you want to back up specific disks to reduce costs, ensure that data on these disks is independent of the rest. Otherwise, data inconsistency may occur.
For example, data of the Oracle application is scattered in different disks. If only some of the disks are backed up, restoration restores only the data of the disks that have been backed up, with the rest data unchanged. As a result, data inconsistency occurs and even the application cannot be started.
- Select Backup Now, enter the name and description, and select Enable for Full Backup.
An auto backup policy has been bound to the BMS. To replace the policy, select Auto Backup and select a new policy from the drop-down list. The original policy will be unbound from the BMS and the new policy will be bound to the BMS.
- Click Apply Now. On the Details page, confirm the specifications and click Submit.
On the Backups tab page, if the generated backups are in the Available state, the one-off manual backup task is successful.
