Application Scenarios
In the event of EVS faults or EVS data loss due to human error, you can use the backup that has been successfully created to restore the data to the source EVS.
Note: After restoring the EVS data, the data at the time of backup will overwrite the EVS data. Once executed, it cannot be undone.
Prerequisites
l The status of the EVS to be restored is Attached or Unattached.
l The EVS to be restored has at least one Available backup.
l If the EVS to be restored is attached with a cloud server, the attached cloud server must be shut down.
Constraints and Restrictions
l VBS only supports the backup and restoration of the EVS as a whole, but cannot back up or restore specified directories or files in the EVS.
l After reinstalling your operating system, the system disk backup cannot be used to restore data to the original EVS. However, you can create a disk and use it as a data disk.
