Backing Up a BMS

Scenarios

To ensure data security, you can back up all EVS system and data disks of a BMS. This backup mode prevents data inconsistency caused by the difference in the backup creation time. The Cloud Server Backup Service (CSBS) offers the backup service for BMSs. It works based on the consistent snapshot technology for Elastic Volume Service (EVS) disks. With CSBS, you can use backup data to restore BMS data, ensuring data security and correctness.

Constraints

BMS backups cannot be used to create images.
BMSs with shared EVS disks cannot be backed up.
When the BMS is restored using backup, the BMS will automatically stop, which will interrupt tenant services. After the BMS is stopped, it is locked for a specified time period during which tenants cannot perform operations on the BMS.

Procedure

Log in to the management console.
Under Computing, click Bare Metal Server.
The BMS console is displayed.
Locate the row that contains the target BMS, click More in the Operation column, and select Create Backup.
The Create CSBS Backup page is displayed.
Perform the following operations as prompted:
- Select a BMS: By default, the BMS to be backed up is selected in the BMS list. Retain the default.
- Configure the backup: Select Auto Backup and select a backup policy.
  
  After the selected BMS is associated with the backup policy, the BMS will be automatically backed up based on the backup policy.
  
  If the selected BMS has been associated with other policy, it will be disassociated from the original policy automatically and then associated with the new policy.
  
  You can also select back up now. The selected BMS will be backed up immediately.
