After an update to Acronis Cyber Protect 15 Update 3 (Build 28035 or 28122) a Virtual Host license does not allow backup of both host and virtual machines.
If the license is assigned to the host, backup of virtual machines fails and VM details show "No license". If the license is assigned to VM(s), backup of host fails.
Protection plan creation may fail with an error similar to:
The protection plan cannot be used or updated for ‘<hostname>’ because the device does not have a license.
Issue in the product.
The issue has been fixed in the build 28503. Please update to the latest build.
