Creating a Cloud Disk Backup
This section describes how to quickly create a cloud disk backup.
If the disk to be backed up is encrypted, the backup will also be automatically encrypted. You cannot manually encrypt or cancel encrypting backups.
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.
- Log in to CBR Console.
- Log in to the management console.
- Click in the upper left corner and select your region and project.
- Choose Storage > Cloud Backup and Recovery. Select a backup tab from the left navigation pane.
- On the Cloud Disk Backups page, click the Vaults tab and find the vault to which the disk is associated.
- Choose More > Perform Backup in the Operation column. In the disk list, select the disk you want to back up. After a disk is selected, it is added to the list of selected disks. See Figure 1.
The system will identify whether the selected disk is encrypted. If it is encrypted, its backup data will be stored in encrypted mode.
- Set the Name and Description for the backup. Table 1 describes the parameters.
Table 1 Parameter description
Name of the backup you are creating.
A name must contain 1 to 64 characters including digits, letters, underscores (_), or hyphens (-).NOTE:
You can use the default name, which is in the format of manualbk_xxxx.
If multiple disks are to be backed up, the system automatically adds suffixes to their backup names, for example, backup-0001 and backup-0002.
Description of the backup.
It cannot exceed 255 characters.
- Choose whether to enable full backup. If full backup is enabled, the system performs a full backup on every associated disk, which requires a larger capacity compared to an incremental backup. See Figure 2.
- (Optional) You can also click the vault name to open the detailed page of the vault. On the Associated Disks tab page, locate the target disk. Click Perform Backup in the Operation column of the disk. See Figure 3.
- Click Yes. The system automatically creates a backup for the disk.
On the Backups tab page, if the status of the backup is Available, the backup task is successful.
If you delete files from the disk during the backup, backup of the deleted files may fail. To ensure data integrity, you are advised to wait until the backup task is complete and then delete data and perform a backup again.
After the backup is complete, you can use the backup to restore disk data. For details, see Restoring Data Using a Cloud Disk Backup.
