Acronis Backup & Recovery 11 licensing is based on the number of machines backed up by the product.
Stand-alone editions
These are the following editions:
The stand-alone editions are designed for backing up the data of a single machine. With any of the above licenses, you can install all the product components on the same machine only. You will be asked for the license key of any of the above editions during the product installation.
Advanced editions (editions with centralized management)
These are the following editions:
These editions are designed for backing up multiple machines. In addition to components that need to be installed on a backed up machine, these editions include a management server that enables centralized management, and storage nodes for storing backed up data on them. Unlike stand-alone editions, advanced editions allow remote connection to a backed up machine.
As with stand-alone editions, a separate license is required for every machine you want to back up. During installation of a licensed component (agent), you can either specify a license server or enter a license key manually. Installation of other components is not licensed. For example, you can install as many storage nodes as you wish - up to 50.
Components of stand-alone editions do not interact with the components of advanced editions.
