A system failure occurs or an unexpected operation is performed on a disk that is attached to an Elastic Compute Service (ECS) instance. In this case, you can use a backup file for the disk in the source region or a backup file that is replicated to the destination region to restore data or create a new disk to restore data.
Prerequisites
A backup file is created for the ECS instance. For more information, see Back up ECS instances.
Background information
The disk backup feature can protect all disks that are attached to an ECS instance. The protection applies to disks that you want to attach in the future. You can also use this feature to protect specific disks. You can use a backup file to efficiently restore a disk based on your business requirements.

ImportantA disk can be restored only if the ECS instance is stopped and no backup file is being created for the disk. After a disk is restored to a specified point in time, the data that is written to the disk after the point in time is cleared. Proceed with caution.
