DAYU Disk Master Free is an imaging backup tool with a lot of bonus features.
The backup side of the program works as you'd expect. Select a target drive, a destination, choose a few options (compression, splitting, priority, speed) and you can run a backup at a click. Restoration is possible from the program or a rescue disk, and there's a disk clone feature thrown in.
The extras start with a "Pre-OS" feature, a bootable recovery environment created on your system drive. Turn this on (Tools > Enable Pre-OS) and "DAYU Disk Master" appears on your boot menu; if Windows won't start then you can launch this and restore a backup. There's also a "command prompt" option which allows you to access your system drive, and perhaps fix any boot problems.
Disk Master also displays SMART data for every compatible drive, a useful check on your hardware's health.
There's support for creating a RAM disk. This can be a neat way to improve your system performance and privacy (save your browser history there and it disappears when you reboot), and the program will by default set your system temp folders to that drive.
Disk Master can even create Virtual Disks, files which can be mounted as virtual drives on demand.
Version 2.3 changes:
- Fix blue screen when you use a deduplicate disk.
- Fix UEFI boot problem, support dynamic system partition.
- Support VSS.
