Azure On-premise Backup on Windows 2008 R2

We have one server that runs Windows 2008 R2 still, too long to explain, and we've recentely decided to move our backups to Azure.

I had no issues on Windows 2016 or 2012 but the backups would not run on Windows 2008 R2 unless Backup Now was click, which is not exactly what one wants from a backup solution.

A scheduled task is created/amended every time you set backup schedule, which is reasonable enough, but the problem that I had was that the task was not working.

This is the task in question



Add Arguments (optional):

-command Import-Module MSOnlineBackup; Start-OBBackup -Name "2cdeaf83-dead-c0de-beef-c345bead15b1
When I tried to run this on powershell, I got this error:

Import-Module : The specified module 'MSOnlineBackup' was not loaded because no valid module file was found in any module directory.
I looked for the path where MSOnlineBackup was and found it here:

'C:\Program Files\Microsoft Azure Recovery Services Agent\bin\Modules\MSOnlineBackup\MSOnlineBackup.psd1'

So, I added this path to the system path and ..... nothing happened, same error.

Desperate times, call for desperate measures, so I changed the arguments on the task to:
-command Import-Module 'C:\Program Files\Microsoft Azure Recovery Services Agent\bin\Modules\MSOnlineBackup\MSOnlineBackup.psd1'; Start-OBBackup -Name "2cdeaf83-dead-c0de-beef-c345bead15b1"

This works.

A word of caution though, any changes to the schedule, will result in the task going back to what it was and thus will not work, so I would suggest creating a new task and ignore the standard task.

I have not tried rebooting the server, which seems to be required for path changes, so use this if you can't reboot for a while???
