Drive Snapshot creates an exact copy of the complete system in a single file. This disk image contains the operating system and all installed programs. The user data and security settings are also exactly taken over by Drive Snapshot in the image. All this takes place during operation of Windows. You can continue to work as normal so during backup. Drive Snapshot takes up only used data on the hard disk in an image. These are pretty fast backed by the Shareware and compressed.
