You can use VBS backups to restore EVS disks to a given point in time or create EVS disks. Data on the EVS disks is equivalent to the backup data.
You can use a VBS backup to restore an EVS disk to the time when the backup was created.
Before restoring the disk data, stop the server to which the EVS disk is attached and detach the EVS disk from the server. After the EVS disk data is restored, attach the EVS disk to the server and start the server.
Instant Restore is a feature that provides the instant restoration function for fast restoring disk data, greatly reducing the restoration time compared with the normal restoration function. For details, see Introduction to Instant Restore.
Only VBS backups in the My backups list can be used for a restoration. Those VBS backups in the Backups shared with me list are unavailable for a restoration.
You can refresh the page after 10 seconds to view the data restoration status. When the Status of the backup changes back to Available, the restoration has been successfully completed.
You can use a VBS backup to create an EVS disk. After the EVS disk is created, the data on the new disk is the same as that in the VBS backup.
Instant Restore also supports fast disk creation using backups, saving your time. For details, see Introduction to Instant Restore.
VBS backups in both the My backups and Backups shared with me lists can be used to create EVS disks.
For details about these parameters, see the parameter description table in "Creating an EVS Disk" in the Elastic Volume Service User Guide.
Note the following items when setting disk parameters:
If it is larger than the backup capacity, initialize the incremental disk space. For details, see "Initializing an EVS Disk (Linux)" in the Elastic Volume Service User Guide.
Instant restoration only takes several minutes to create a new disk by using a backup.
This disk status changes from Creating to Available, Restoring, then Available. Instant restoration is so fast that you may not notice the Restoring state. After the state has changed from Creating to Available, the new disk has been successfully created. After the state has changed from Restoring to Available, backup data has been successfully restored to the created EVS disk.
