-On a common personal system using a nearly-full 2 TB M.2 SSD, this type of scan will take approximately 10-15 minutes.  The type of disk drive and connection mechanism will greatly influence the speed of the snapshot due to the potential for increased read-times.  I would recommend only snapshotting required directories and extensions when possible.
