I have a non-Azure Server (on Premise - Win2012) running MARS Agent for Backup of Files and Folders. The Backup appears to be running normally (Server Perspective) -- using the agent software on server the backup jobs completes daily.
BUT - the Recovery Services Vault reports it differently. I was getting a job "failed" every day since about 12/7. My last reported failure was on 2/27. After that backup stopped reporting. (from the Azure Portal view of the Backup Jobs in the Vault). I have two 3 week old jobs for the Server showing as "in progress" and I cannot cancel this via Portal. The Backup Items view (in Vault) is correctly updating with the latest recovery point, even though the overall status is showing as "Failed" for that backup item.
NOTE: On another thread I seen someone have this exact same problem. Their fix was updating the agent on the server side. When I try to update my agent on the server side I run into an error and the agent service gets disabled causing the agent to never update. I also did try to re-register the agent to the recovery service.

Please verify your MARS agent is up to date. An outdated agent can cause connectivity issues with the Azure Recovery Services Vault, so it’s important to verify that you're running the latest version.
Ensure there is proper network connectivity between the MARS agent and Azure. Please check if there are any firewall rules or proxy settings that might be blocking the connection. If so, those need to be adjusted accordingly.
The MARS agent service may have been disabled, especially during updates. Please check the Windows Event Viewer for any errors related to the MARS agent. This may provide more insight into why the service is failing.
Get-ExecutionPolicy -List Set-ExecutionPolicy UnrestrictedIf the agent is still not working as expected, try uninstalling and then re-registering it with the Azure Recovery Services Vault. Be sure to use the same passphrase that was originally used during registration.
If the upgrade process is failing, it might be due to missing installation files in the Windows Installer cache. In this case, you may need to manually reinstall the MARS agent.

2025-03-26T17:07:26.7633333+00:00 When trying to update the MARS agent on my on-prem server this is the error I am getting, and this is the service that gets automatically disabled. I tried enabling the service and set it to auto when I try to run the update but still errors out. Connectivity seems fine and the recovery vault shows recovery points but will not show any backups after 2/27/25. I even tried re-registering the agent and set a new passphrase. I see where backups are being made locally but nothing shows in the recovery vault.

Older versions of the MARS agent may sometimes cause issues with updates or connectivity. Please verify that you’re using the most recent version.
If the update fails, please review the OBPatch.log file in the installation folder for specific error messages. This file can provide more detailed information on what went wrong and help in diagnosing the issue.
https://learn.microsoft.com/en-us/azure/backup/upgrade-mars-agent#update-the-mars-agent-installation-on-the-serverCheck that the clock on your server is set to the correct time zone. Time discrepancies can sometimes lead to issues with backup synchronization and cause failures in the backup process.
Take a look at the Backup Logs in the MARS agent console for any warnings or errors. These logs might offer additional insights into what could be causing the issue.

Error 1603 is a common installation issue with the Azure MARS agent, and it can occur due to various reasons, such as conflicting software, insufficient permissions, or missing prerequisites. Uninstalling and reinstalling the agent might help, but there are additional troubleshooting steps you can try:
Check System Requirements:
Ensure your system meets the minimum requirements for the MARS agent, including having .NET Framework 4.5.2 or later installed.
Ensure your service is running on TLS 1.2 version
https://learn.microsoft.com/en-us/azure/backup/backup-azure-mars-troubleshoot#before-you-start
Review Installation Logs: The MARS agent generates log files during installation, which can provide clues about the issue. These logs are located in the %TEMP% directory.
Disable Conflicting Software: Temporarily disable antivirus or firewall software that might interfere with the installation.
Update the Agent: Make sure you're using the latest version of the MARS agent.
Uninstall and Reinstall: If the above steps don't resolve the issue, uninstall the agent completely and reinstall it using the latest installer.

Apologies for the inconvenience this may have caused to you.
I even tried re-registering the agent and set a new passphrase. I see where backups are being made locally but nothing shows in the recovery vault.
You mentioned that you have tried re-register the agent with the new passphrase. but it should be done with the same passphrase that was originally used during registration.
Please follow the same and let us know the results.
Note:
- make sure if you have antivirus software installed on the server, Ensure the MARS agent is excluded from the antivirus installed on the machine.
- Don't ignore to check for Proxy on the server. if you find any proxy please remove it.
here are the steps to verify the proxy from control panel.
Click Start > Control Panel > Network and Internet > Internet Options > Connections tab > LAN Settings> look for the proxy server check box> If you find any proxy removes it and click ok.
And if the above steps don't resolve the issue, uninstall the agent completely and reinstall it using the latest installer. However, before going to reinstall the agent, follow these steps.
- Ensure .NET Framework 4.5.2 or later is installed on the server
- Verify MARS Agent version
- Remove all the dependencies of old version of MARS agent (registry keys, services and folders C:\Program Files\Microsoft Azure Recovery Services Agent).
- Update .Net Framework and MV C++ 2008
- Remove regkeys, as mentioned in this article
- Disable UAC by following the below steps and restart the server again
- Click the Start menu.
- In the search field type UAC.
- Click "Change User Account Control settings"
- In the window that comes up, move the slider down to "Never Notify"
- Click OK.
- If you see error regarding any provider missing, then install the missing provider before agent installation process and reinstall the MARS agent.
- Check if the PowerShell version is not latest then it is necessary to update Windows Management Framework and Microsoft .NET Framework to the latest version. To download the latest versions use below links:
- After upgrading the versions restart the server.
Then download the latest version of the MARS agent from the Azure portal. Install the agent by following the installation wizard instructions. and reconfigure your backup settings using the information you noted down earlier. Then Re-register the Server.
Please try the above all steps and let me know the results.
Thanks
