A snapshot is created so the backup remains in a pristine state and all user write operations are redirected to that snapshot, users then work off the backup virtual machine (VM) and the recovery process begins in the background. Users have no idea the recovery is taking place, and once the recovery is complete; the user workload is redirected back to the original VM.
