I’m a Var.
May I buy “Change block tracking for UrBackup Client on Windows - 2.x” and install it at my customers?
Is there a procedure for license registration or is sufficient my invoice to the customert?
It looks like purchasing one copy of CBT for every set where you install and use CBT is sufficient. Licenses do not appear to be assigned to specific machines.
From the Change Block Tracking FAQ:
How is the licensing enforced? Is there a license server? Does it need a internet connection?
At this time licensing is not enforced, there is no license server and it does not need a internet connection. This is done with the hope that you will not illegally use change block tracking without having purchased a license. It may become clear that the license needs enforcement via software, in which case a license server will be supplied.
