Create a VBRComputerBackupJob with "OS Volume" as one of the selected volumes

[neil1]

In the Veeam Backup and Replication Console GUI, I can specify "OS Volume" as one of the selected volumes for a Windows Agent job. How can the same thing be achieved in Veeam Powershell?

I have tried passing

Code: Select all

-SelectedVolumes @( "OS Volume" )

as an option to the

Code: Select all

Add-VBRComputerBackupJob

function, but this produces the error "Add-VBRComputerBackupJob: The specified computer backup job is invalid. Source: The Specified volume path is invalid: OS Volume\.".

As a test, I used the GUI to create a Windows Agent job named "xxtest" having "OS Volume" as its one and only selected volume. Then, I passed

Code: Select all

-SelectedVolumes @( (Get-VBRComputerBackupJob -Name "xxtest" ).SelectedVolumes[0] )

as an option to the

Code: Select all

Add-VBRComputerBackupJob

function. The function completed without errors and successfully created a new Windows Agent job with "OS Volume" as a selected volume. This test shows that it is possible to create a new VBRComputerBackupJob that has "OS Volume" as one of the Selected Volumes, but I am hoping for some technique that does not require a special manually-created existing VBRComputerBackupJob .

Hi @@neil1,

Try passing "OS" to it; checking the backend code, it looks like it parses for this. Worked in my lab:



I will write the Technical Writers and ask them to please update the documentation.

I can confirm that

Code: Select all

-SelectedVolumes @( "OS" )

does the trick. Thank you david.domask .

I agree that the "OS" value deserves to be mentioned in the documentation -- probably on the pages for the Add-VBRComputerBackupJob and Set-VBRComputerBackupJob functions. It would also be nice for the docs to say how to specify a volume based on GUID, if possible. "-SelectedVolumes '\\?\Volume{44aca03b-7976-4af1-adc6-965de358b69e}' ", for example, does not work.

Hi @@neil1, very glad to hear it worked. The TechWriters have already updated the documentation and added an example (#5):

As best I can tell, the cmdlet is expecting a normal letter volume name. I think probably feature request on this one for VolumeID adding -- what is the use case if I can ask? Not saying it's a bad idea just curious on the use case.
