Query: Setting up Automatic Power-Off After Veeam Backup Completion

I assume this is a Backup Job within Veeam Backup & Replication? And, you want to power off a server/computer after the job is finished? What you could do is, within the Job > Storage section > Advanced button > Scripts tab, create a powershell script to power off the computer after the job runs.
 

See here from the User Guide. Make sure the script (PoSH, or whatever language you choose) is placed in a local folder on the Veeam Server, then browse to the folder and select the script. 

As with any Job change, I would test this first before using in production. Create a test job with a couple test VMs. Create the Script to power off 1 of the VMs (or all of them if that’s what you wanna do), then create the Job & adding the script. Run the Job and see if it behaves as you want it to.

Did you test your script alone to verify it works? If so, and again..if your script is on the Veeam server, yet still doesn’t work, I’d reach out to Veeam Support to get some assistance.

You can try disabling UAC on the system...if your org policy allows you to. Or to test, at least disable it for 1 job run to see your script successfully executes.

Another thing to be aware of, the script executes as the account used for the Veeam Backup Service on the VBR server. You can try a domain account to use for the Veeam Backup Service account. Place the domain account in the local Administrators group on the VBR server, as well as grant it Log On As a Service and db_owner rights to the configuration DB. Then, on the server in the job you want to execute the script against, add the domain account to the local Admin group there then re-attempt your Job and script.

As an aside from the conversation, why do you want the Veeam server powered down? That will just make your RTO longer for performing restorations?

 @MicoolPaul I do have my reasons for powering off this server. We have four Veeam servers, each one efficiently performing its job. There's no need to have two servers running continuously and consuming electricity. I'm referring to physical servers.

Hi @VEEAM_Legend , I interpreted incorrectly what you’re goal was here. You aren’t wanting to power down a VM server within a Backup Job after a Backup Job run, but rather power down the VBR server? There is no way to do this within Veeam. There is only 1 way I know of to accomplish this. You can do so in Windows, but it would be a bit of a guessing game → to configure this, you simply need to create a Windows Task in Task Scheduler to run your powerdown PoSH or BAT script after all your jobs run. This is where the ‘guessing game’ comes. You need to set a time for the script Task to run when your jobs are finished. The only way to know when they’re finished running is look at the Job history of the last running job and see how long it takes to run...or at least the longest time it takes to run. Then configure the Task to run a set time (an additional hr?) after the longest Job run time just to be safe. 

Obviously, this isn’t ideal because a job could take longer for any of a number of reasons → problem with the backup method causing it to revert to Network mode and thus taking longer; healthcheck and other maintenance tasks which generally run after a job and take an unknown variable amount of time to complete, etc.

Sure..no problem. I’m not sure it’s something Veeam would consider adding, but it wouldn’t hurt to go over to the forums and add a feature request post for what you’re wanting.
