The error you are getting is:
E Feature Usage Issues:
- License not selected for host server '192.168.0.6'
To resolve this you simply need to select a license for the host server.
You can select/change the license edition that is assigned to a host server in vBackup via the Usage tab on the Configure Licensing screen (Tools > Configure Licensing > Usage tab > select host server > choose license type from drop down). This can also be done via the Product Licensing section of the Edit Host Server wizard (right-click host server > click Edit Properties).
Hope this helps.
