The veeamconfig command is for Agent for Linux. You have installed the Agent, correct? I assume you're typing that cmd on your Linux computer? Try typing just veeam instead. 

Yes, sorry, it should be "Veeam.EndPoint.Manager.exe" but that application is also absent.
It is part of the Agent, not of Backup & Replication it seems.

I run backup jobs on a Backup & Replication server which I connect to external servers to backup, so I’d like to run everything on my local server.
Should I install the agent on the Backup & Replication server for this?

Are you using Agent for Windows or Linux?  That will help with determining file locations, but the command files mentioned should be installed even with CE edition.

I run Backup & Replication on a Windows 2022 Standard server.

So you are running the Community Edition of VBR and not the Agent?  Or the Agent?  Just need clarity to hopefully help further.

Yes, I installed VBR and not the agent on the Windows 2022 server.
I guess I need to install an agent on this system as well?

The link you referenced in your OP is the Agent not VBR so yes.  You can deploy the Agent from the VBR console or install it.

Ok, so everything is just a bit confusing here. If you installed VBR Community Edition, there is no command line, well except for Powershell cmdlets. You use the Veeam Console to start backing up devices. With Community Edition, you have 10 free “instances” you can backup, beit VMs or physical devices. If you don’t want to use VBR to backup physical devices...that is fine..and it sounds like you don’t. You just need to install the Veeam Agent. If you want to backup Linux, Install Veeam Agent for Linux. For Windows, Veeam Agent for Windows. Does that help?

You don’t really need Veeam Community Edition installed...just the Agent for Windows if you’re just wanting to backup just that Win 2022 server. 

Thanks, the agent provided the commandline functionality but this is for the agent. It look like this needs to run on the target system, not on the VBR server.

My idea was to create a single batchfile on the backup server to

1. enable the NIC
2. connect the VPN to the external server
3. run the VBR backup job to backup the external server
4. disconnect VPN
5. disable the NIC

This to minimize the connection time with the external system.
Therefore I need to run the command for the backup (3.) from the backup server, not the external server.

Yes has to be on the system you want to back up.  If you are looking at backing up remote systems then VBR is the way from this server and you could deploy the Agent to the remote server.

I would prefer to keep everyting on our local backup server so we can close down the connection when finished. If I run the agent on the remote server I don't know when to close the VPN connection (and disable the NIC).

Then you would be better off running VBR on the server and deploying the Agent to the remote server.  I get the scripting part but it will take longer to fiddle with this part versus going the easy route.  You can create a backup job on the VBR server for the Agent including running scripts before/after to accomplish some of the tasks.

It is no problem to control LAN and VPN connections to remote servers and back them up, this way we are independent of the remote server and have total, local control. Only thing is that we give the backup job a time window longer than necessary, I'd like to bring that down to the minimum. 
Perhaps I can use the build-in powershell interface in VBR to kill the connection as soon as the job is done.

Yes the PowerShell interface is more powerful and would be something to explore for sure.

Hmm..well, what you could do is use VBR to ‘push’ an Agent to the remote system, run a few or more backups, see how long it takes, then take the longest time and add additional time then run your script. You can do a pre/post script...although don’t recall if those are available for Agent-based jobs off hand.

Pre/post scripts sounds great, however, a simple batch file syntax containing “cmd.exe” doesn't do anything, Googling this is very discouraging.
Can you point me to some examples?

HI @mvandek2 -

You can run pre/post scripting for Agent jobs only if you use VBR to do the backup of the computer (i.e. Management of the Agent through VBR). See:

https://helpcenter.veeam.com/docs/backup/agents/agent_job_advanced_scripts.html?ver=120

and here:

https://helpcenter.veeam.com/docs/backup/agents/agent_job_vss_scripts.html?ver=120

Doing an Agent for Windows Standalone doesn’t allow pre/post scripting.

You can use any script type… .bat, .ps1, .vbs, etc. Guest processing side scripts only are for guest OS quiescing, so scripting there would be no use for that area of scripting. I think you should be able to do what you want with the Agent Job Scripting though. You'll just need to test it out. The script needs to run on the Backup Server itself, in any location you decide. Then in the Job settings > Storage section > Advanced button, Scripts tab enter the location of the script, as the example shows in the 1st link above. 

Hope that helps.

Thanks but the link you sent does not contain any examples, am I missing something?

Are you wanting examples of scripts? Veeam doesn't provide examples, just where to place them. 

Yes, I am looking for examples because I cannot get the simplest .bat file to do anything.

As Shane mentioned there are no examples of scripts unless someone else has posted something.

Any .bat file I configure as pre script gives errors or hangs without any feedback.
Why is this so complicated...

Check here for details on scripts - https://helpcenter.veeam.com/docs/backup/hyperv/pre_post_scripts.html?ver=120

Try looking in the Backup Job log to see if it shows anything on why the Script isn’t (seemingly) doing anything. It should be on the VBR Server at:

C:\ProgramData\Veeam\Backup\<job-name>.log
