Just a quick post on an interesting issue with the Guest Credentials test in Veeam Backup & Replication we’ve seen last week. Instantly after clicking “Test Now” in the Guest Processing section of a certain backup job, an error was displayed.
"Building list of machines to process Error: (Child group-vXYZ (Folder) for object XYZ was not found)"
Normally you see such errors with vSphere when a certain object has been deleted or recreated. While Veeam displays names of objects, internally it works with MoRef IDs. So we’ve checked the job selection, custom credentials and the application aware processing settings. But all listed objects were still valid, especially no folders where used anywhere.
We’ve contacted Veeam Support and had a remote session. The support engineer discovered some orphaned VM folders in the exclusions. After removing those, the error disappeared and the credential check worked again. From a logical point I thought those weren’t relevant for the check, so I didn’t check them.
So, if you experience this error and can’t find the cause, better also take a look at the exclusions 😉
