I have Acronis Backup Advanced 11.7 for PC licenses.
I see in Acronis, option to connect to a management server, so management server required additional licenses or I can use my licenses.
Welcome to Acronis user forums!
The Acronis Backup Advanced suite is designed for backing up multiple machines. In addition to components that need to be installed on a backed-up machine, these products include a management server that enables centralized management and storage nodes for storing backed up data. Usage of these additional components is not licensed. For example, you can install as many storage nodes as you wish - up to 50.
The only licensed component is the agent, that needs to be installed on the backed up machines.
