What it does Full system imaging: Create an exact image of your whole drive (including Windows) so you can recover from crashes, malware, failed updates, or drive replacement. File & folder backup: Back up only what you need - documents, photos, projects or combine it with full images for total protection.

Incremental/Differential backups: Save time and storage by backing up only changes after the first full image. Clone & migrate drives: Ideal for moving to a new SSD/HDD - clone the system and keep working without rebuilding.
