The best free Windows backup program on the planet:
For our commercial products like SyncBackSE and SyncBackPro, one registered copy of the software may be used by a single person who uses the software personally on up to 5 computers to process personal data (home use). When used to process non-personal data (e.g. the workplace, but including processing non-personal data on a personal computer), a separate license must be purchased for each installation of the program (including one per virtual machine). Installing the program on a single workstation used non-simultaneously by multiple people, counts as one installation.
