Case #07129090
I have a physical machine which I have added manually to the Managed group.
The machine backed up fine via B&R (community Edition 11, newest patch) but stopped working at the end of last month (probably when I deactived the standard administrator account of the domain and replaced the name of the account with something not that obvious but have added the new credentials to Veeam B&R also).
As the agent "failed to connect" (although network connections were working) I have upgraded it from v5 to v6 and afterwards started the backup through the B&R console which resulted in the following error:
Error: Failed to retrieve the value of the Boolean by name 'FIResult'
I have not been able to find anything regarding that specific error message on the net so I'm at a loss.
What shall I do?
Thank you very much for your support.

Hello Thorsten

- Veeam Agent v6 requires Veeam Backup & Replication V12
- Veeam Agent v6.1 requires Veeam Backup & Replication V12.1

Please update your backup server accordingly. Your v11 server is not compatible with Agent v6. It may solve the issue you see.
Best,
Fabian

Thank you for advising about agent compatibility, I have not thought of that.
