Re-create Snapshot

This command starts a new copy-on-write operation by using an existing
snapshot virtual disk. You can re-create a single snapshot virtual disk or re-
create multiple virtual disks.
CAUTION:
stop any data access (I/O) activity or suspend data transfer to the source virtual
disk to ensure that you capture an accurate point-in-time image of the source
virtual disk. Close all applications, including Windows Internet Explorer, to make
sure all I/O activity has stopped.
NOTE:
Removing the drive letter of the associated virtual disk in Windows or
unmounting the virtual drive in Linux helps guarantee a stable copy of the drive for
the Snapshot.
