I have a FortiAnalyzer VM that I am backing up with Veeam B&R v11a (build 188.8.131.521 P20211211). The backup reports success and I have restored the entire VM (after a bad firmware udpate) so confident it is working. Occasionally I see a warning message from Veeam that it was not able to access the guest OS, although it does still report the normal volume of data backed up.
In the backup job properties I can set specific credentials for the VM. It offers Standard or Linux. I am using my normal admin user account but am not able to guess the correct settings to pass the Credentials Test.
Tried searching in the Veeam community forums as well but no joy.
Does anyone do similar, and if so, how have you configured the backup job?
