This article covers the scenario when an workstation or server license was applied to a windows agent prior to a backup plan being created that included features requiring a higher level license.
The backup plan will fail to run and the end user will be prompted with an error similar to below:
A license may exist in the console but is not assigned to the agent assigned a backup plan that requires a higher level license.
The user should navigate to the Acronis backup console, select Settings > Licenses and locate the appropriate available license that meets the requirements of the plan. Once selected, a menu will show on the right hand side with an option to assign it, once assigned to the agent with the backup plan, the plan can now be run with the advanced features.
