This section describes how to quickly create a cloud disk backup.
During the cloud disk backup, the performance of the disk is not affected. To ensure data integrity, back up the disk during off-peak hours when no write operation is performed on the disk.
A disk can be backed up only when its status is Available or In-use. If you have performed operations such as expanding, attaching, detaching, or deleting a disk, refresh the page first to ensure that the operation is complete and then determine whether to back up the disk.

On the Backups tab page of the Cloud Disk Backup page, if the status of the backup is Available, the backup task is successful.
If you delete files on the disk during the backup, the deleted files may fail to be backed up. Therefore, to ensure data integrity, you are advised to delete the target data after the current backup is complete and then perform a backup again.
After the backup is complete, you can use the backup to restore disk data on the Cloud Disk Backup page. For details, see Restoring Data Using a Cloud Disk Backup.
