How To Fix Veeam Backup & Replication— Unable to allocate processing resources error.
Unable to allocate processing resources. Error: On-host proxy [backup] requires upgrade before it can be used.
I wanted to move a virtual machine on a previously working host to a new host. The virtual machine was successfully moved and worked, but when I created a new backup job for the virtual machine I moved on the new host, the backup failed. Actually, this error is not related to the virtual machine. The problem is with Veeam Backup services running on the host.
When I looked at the details of the error, I got a warning like below.
For your information, both hosts are using the Hyper-V Server 2019 Core platform. Veeam Backup And Replication V. 12.0.

Host discovered succesfully. Now you can go to Home menu and start to manuel Job for the backup. If the backup is successful, you do not need to go to the second step. The second step contains a different solution to the error.
How to Resolve — Solution 2
