Veeam Backup and Replication Failed to mount files: Mounter is in 'failed' state Mount Process aborted Agent failed to process method (Mount.GenericMount

Hello.

Used VEEAM 12.2.0.334

Veeam Cloud Virtual Machine

Using agents for Windows operating systems, I copy and backup data.

Virtual machines on Linux can recover granular files.

When trying to restore Windows files, an error occurs when mounting FLR browser.

Veeam is installed on a Windows 2019 server, reduplication is enabled on it.

Using the agent, I make AD backups and can restore files.

But if I do exactly the same task on a friend’s virtual machine, changing only the virtual machine that I want to copy, I can’t restore the files.

It turns out to do instance recovery and extract data from the running VM.

But when copying, exchange does not allow you to restore letters. If I backup only drive C, then I can restore the files of the Windows guest operating system.

Although the tasks are completed without errors.

It turns out that the backup browser works very selectively.

Maybe because some virtual machines have a server core?

Hi @scalexey -

Hmm..not sure why FLR works sometimes and sometimes not. Server Core is supported, as long as you have the Desktop Experience feature installed, as per the User Guide:

https://helpcenter.veeam.com/docs/backup/vsphere/system_requirements.html?ver=120#microsoft-windows-server-core

You could look at the logs in: C:\ProgramData\Veeam\Backup\<restore-name>.log and see if there’s anything in those to help pinpoint the issue.

As far as for Sys Req’s for use with Veeam Agent, Core is supported as long as you manage the Agents through Veeam Backup:
https://helpcenter.veeam.com/docs/agentforwindows/userguide/system_requirements.html?ver=60

Take note: “Veeam Agent operating in the standalone mode does not support Server Core installations”

Let me try to clarify again, I have veeam on a 2019 server with a GUI.

The servers that I want to copy to have OS server windows core installed/ and with the core versions there is a problem loading FLR backup browser

If you don’t have Desktop Experience on them @scalexey , then yes...according to the Guide, you probably won’t be able to use that OS. You can contact Veeam Support to verify.

Привет.

three hours ago I could restore my letter. Now the equipment will not start.

I asked to add the veeam folders to exceptions on the antivirus software solution.

@scalexey -

When you post, please do so in English so we can try to help. That said, Veeam Support is really the place to share logs with.

For A/V exclusions, see Veeam’s KB1999:

https://www.veeam.com/kb1999

Hopefully adding those will help your issue.
