Drive SnapShot creates an exact image of a running Windows system, including open files and RAID setups, without rebooting into a special environment. Images can be restored to the same disk or mounted and explored as a virtual drive.
The entire tool is a few megabytes and includes bootable recovery media, AES encryption, differential images and a scheduler. It also supports restoring a system image back onto the running machine.
Windows 7/8/10/11, 32/64-bit
