Creating a VBS Backup

Precautions

• An EVS 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 an EVS disk, refresh the page first to ensure that the operation is complete and then determine whether to back up the disk.
• You are advised not to back up an EVS disk larger than 4 TB.

Create a VBS Backup (Method 1)

1. Log in to the management console.
2. Click . Under Storage, click Volume Backup Service.
3. On the VBS page, click Create Backup.
4. From the EVS disk list on the left, click to select the EVS disks you want to back up. Then they appear in the Selected Disks list on the right. You can click in the Operation column to delete EVS disks that do not need to be backed up.

5. Confirm that the EVS disks selected for backup are correct. Then in the Configure Backup area below, set Auto Backup or Immediate Backup or both.
   

   Auto Backup: The selected EVS disks will be associated with the backup policy. If the policy is enabled, the EVS disks will be automatically backed up according to the backup policy. If the selected EVS disks have been associated with another backup policy, they will be disassociated from that backup policy first and then associated with the new backup policy.

   Immediate Backup: backs up the selected EVS disks at once.

   • Select Auto Backup: In the Backup Policy drop-down list, select an existing one. You can also click Create Policy to create a new one. For details, see Data Backup Using a Backup Policy.
   • Select Immediate Backup: Enter the backup name and description. Table 1 describes the parameters.
