Veeam: Unable to allocate processing resources. Error: One or more errors occurred. / Waiting for the next task failed Job has failed unexpectedly

This has a simple solution;

Jobs could be stuck in a loop. Ensure you have the last veeam update installed and also at last instance restart Veeam services using the following Powershell Script:

 
Get-process | where {($_.Name -like "Veeam*")} | stop-process -Force
Get-Service | where {($_.Name -like "Veeam*")-and ($_.Status -eq "Running")} | Stop-service -Force
Get-Service | where {($_.Name -like "Veeam*")-and ($_.Status -eq "Stopped")} | Start-service
