Ok, I'll explain what I'm trying to do first. Previously we have used Server Backup to backup to multiple disks (not all at one time). We would have Monday1, Monday2, Tuesday1, Tuesday2 etc. I used to use wbadmin to add drives to the backup after I created the backup initially. I would do wbadmin get disks and find the ID of the drive that was currently plugged in. Then I would use the command: wbadmin enable backup -addtarget:{diskID} and the drive would be added to my scheduled backup.
When I try to do this in Server 2012 Essentials I get the error: ERROR - The specified backup location could not be found or is not a supported backup storage location. I cannot add the drives in the GUI because it requires all previously added drives to be plugged into the system. Sorry but I don't have 12 SATA ports. : /
I was running the wbadmin commands from an elevated Powershell prompt. That is another thing, even though I've disabled UAC why do I have to run everything as administrator? It is kind of concerning, as I'm afraid a lot of 3rd party software packages aren't going to work. I'm logged in as the administrative account I set up during the install.
