A is a point-in-time image of a standard virtual disk. A snapshot virtual disk is typically created for backup purposes. The stays online and accessible to hosts while the backup application accesses and reads the data on the snapshot virtual disk.
You can select a snapshot virtual disk as the source virtual disk for a virtual disk copy. This is one of the best ways you can apply the snapshot virtual disk feature, because you can do a complete backup without any impact to the storage array I/O.
Note:
If you choose the source virtual disk of a snapshot virtual disk as your target virtual disk, you must disable all snapshot virtual disks associated with the source virtual disk before you can select it as a target virtual disk.When you create a snapshot virtual disk, you automatically create a . The snapshot repository virtual disk stores information about the data that has changed since the snapshot virtual disk was created. You cannot select a snapshot repository virtual disk as a source virtual disk or as a target virtual disk in a virtual disk copy.
You can use the Snapshot Virtual Disk feature with the Virtual Disk Copy feature to back up data on the same storage array and to restore the data on the snapshot virtual disk to its original source virtual disk.
Use the feature to back up data, to copy data from disk groups that use smaller capacity physical disks to disk groups that use greater capacity physical disks, or to restore snapshot virtual disk data to the source virtual disk.
The Virtual Disk Copy feature copies data from the source virtual disk to the target virtual disk in a one storage array.
Note:
The target virtual disk capacity must be equal to or greater than the source virtual disk capacity.
