I had a strange problem with one of my VM’s. The VM-ID was changed and this change was not forwarded to my vCenter server. I use Veeam Backup for creating backups and the job skipped this VM with the following error:


This problem can be solved by restarting the services on the ESX server and the vCenter server.

The following command will do this on the ESX Server.

service mgmt-vmware restart

For vCenter (Windows) you can do this from the command line:

net stop "VMware VirtualCenter server"

net start "VMware VirtualCenter server"

After restarting the services, the backup job completed successfully.
