If a system failure or faulty operation occurs on a disk attached to an Elastic Compute Service (ECS) instance, you can restore the original disk or clone a disk by using a backup point in the source region or a backup point replicated to the destination region.
Prerequisites
An ECS instance is backed up. For more information, see Back up ECS instances.
Background information
Disk restoration protects all disks that are attached to ECS instances, including the disks that are subsequently attached. This feature can also protect specified disks. To efficiently restore a disk, you can use a backup.
Precautions
On the Disk Protection tab, you cannot delete backup points from Cloud Backup to ensure data security and prevent accidental operations.
Restore the original disk
If a system failure or faulty operation occurs on an ECS disk attached to an ECS instance, you can restore the disk by using a backup point.
Log on to the Cloud Backup console.
In the left-side navigation pane, choose .
In the top navigation bar, select a region.
Click the Backed-up ECS Instances tab.
Click the
icon before the required ECS instance. On the Disk Protection tab, click an available backup point and click Restore.
ImportantYou can roll back a disk only when the ECS instance is stopped and no backup is being created for the disk. After an ECS disk is rolled back to a specified point in time, the data that is written to the disk after the point in time is cleared. Proceed with caution.
In the message that appears, click OK.
After you create the restore job, you can view the progress on the Jobs tab.
Clone a disk
If a system failure or faulty operation occurs on a disk attached to an ECS instance, you can clone a disk by using a backup point.
Log on to the Cloud Backup console.
In the left-side navigation pane, choose .
In the top navigation bar, select a region.
Click the Backed-up ECS Instances tab.
Click the
icon before the required ECS instance. On the Disk Protection tab, click an available backup point and click Clone.
In the Create Disk from Backup panel, select the ECS instance to which the new disk is attached. Click Next.
On the Set Mount Parameters tab, select a disk type and click Create.
After you create the restore job, you can view the progress on the Jobs tab.
