Here are some key features of "Drive Snapshot":
Create Disk Image Backups, while running Windows
There is no restart (to DOS) necessary. Never.
Continue your work, while the Backup is in progress
The new Snapshot technology ensures, that all data are consistent, and reflect the PC's data at the start of backup. There are no difficulties with opened files. Never.
This enables a very fast and easy way to backup servers and other computers, that must run 24 hours a day.

This works with any program of your choice, including (of course) the Windows Explorer
