#. In the ECS list, locate the target ECS and choose **More** > **Manage Image/Backup** > **Create Disk Backup**.

- If the ECS has been associated with a vault, configure the backup information as prompted.
- If the ECS has been associated with a vault, configure the backup information as instructed.

- **Server List**: The ECS to be backed up is selected by default. Click |image3| to view the disks attached to the ECSs. Select the disks to be backed up.
- **Name**: Customize your backup name.
- **Description**: Supplementary information about the backup.
- **Full Backup**: If this option is selected, the system will perform full backup for the disks to be associated. The storage capacity used by the backup increases accordingly.

- If the ECS is not associated with a vault, buy a vault first and then configure the backup information as prompted.
- If the ECS is not associated with a vault, buy a vault first and then configure the backup information as instructed.

An incremental backup backs up only the data changed since the last backup, which is storage- and time-efficient.

When a backup is deleted, only the data blocks that are not depended on by other backups are deleted, so that other backups can still be used for restoration. Both a full backup and an incremental backup can restore data to the state at a given backup point in time.

When creating a backup of a disk, CBR also creates a snapshot for it. Every time a new disk backup is created, CBR deletes the old snapshot and keeps only the latest snapshot.
