Due to fact that the "hidden" SBS 2011 BU disk is a VMware virtual store which is now full I must quickly add space to VMware. Therefore I want to to stop SBS 2011 BU and remove the BU-disk from Disk Management completely.
How to do this? Surely I don't just Delete the Volume on Disk Manger. I suppose I must somehow completely stop/remove SBS 2011 BU task.
