Windows PC Backup Failed - Access Denied

L

Hi wondering if anyone can help with an error I am getting on a backup

 

I have a few hyper v VMs backing up and a couple of Windows 10 machines.

1 machine is causing a bit of hassle and was wondering if anyone has seen this before.

I see this warning message in the GUI:

26/03/2024 13:55:22 :: Collecting recovery media files Details: Access is denied  

 

I see this in the logs:

[26.03.2024 13:57:35] <01> Error    Failed to add recovery media files to the backup

Thanks in advance for any help,

Is this log from one of the Windows 10 machines?  If so with the Access Denied error, I would assume at this point permissions related and would need more investigation.

Hi Chris,

Small error on my part I meant windows 11.

But, Yes this is from one of the windows 11 machines

Its strange because im using admin creds for all windows 11 pcs and its just this one with the error.

 

On a further note: The user logged into the PC is the same as the admin creds I am using to run the backup. Could that be the issue? 

I cant run the backup with local admin creds as I am storing to a NAS.

I cannot see the logged in user credentials being the issue but are you able to use another Admin just to test rather than the logged-on user?  It would be a way to narrow it down possibly.

@loughraj - another way to possibly narrow down where the ‘access’ issue is, is to look at the other Win11 machines which are fine and look at the log process for those to see where Veeam is accessing at each step. Maybe something stands out that’s different between the success and failure computers?
