DMZ server backup

[NikDave]

Hi Guys,

#07105012

I have a strange problem going on with a web server in the DMZ, all the servers are virtual.

I done an in place upgrade last week from server 2012 to 2022 and now the backup fails with:

Failed to inventory guest system: Veeam Guest Agent is not started
Failed to prepare guest for hot backup. Error: Failed to connect to guest agent. Errors: 'Cannot connect to the admin share. Host: [SERVER]. Account: [ADMIN]. Win32 error:The network path was not found. Code: 53 Cannot connect to the admin share. Host: [IP ADDRESS]. Account: [ADMIN]. Win32 error:The network path was not found. Code: 53 '

The server lives in a vSphere folder with many servers, where it grabs all defaults but I change the username and password for this server because its in the DMZ.

Whats odd though is if I create a new job just to backup that server, it works fine!

Do I need to add permissions into vSphere? The virtual machine was newly created.

Thanks for your help
Dave

Hello Dave

You can use the credentials button in your backup job to specificy dedicated credentials for the DMZ VM:


If the provided user is not the built in "administrator" account, you probably need to disable Remote UAC on the target machine. That's a limitation from Microsoft.

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
DWORD: LocalAccountTokenFilterPolicy
Value: 1

Best,

Hi Fabian,

Thanks for the into

Yeah I changed the individual machine credentials already but did try UAC and a restart and that didn't seem to make much difference.

I think I've found whats happening, but not sure how to fix it lol

I seem to have 2 DMZ servers when I test the credentials, one fails almost instantly and can't find it in VC, I think thats the one i'm putting the credentials in for.

The other one I think is failing because its using the default credentials, which wont work.

Thanks
Dave

I think I might have it, have just worked out how to remove the old one!

Just testing now

[NikDave]

Yeah, its all ok now.

It was still seeing the old VM, removed that one and added the new VM from the folder and its happy

Thanks
