It works when trying to create a copy on the local disk ( from D:\ to D:\ lets say) but not when I try to set it to another disk (from D:\ to S:\ for example)
I was expecting to create a shadowcopy on a different disk but was getting the error you see in the screenshot.
Error: Failed to create storage area association. (Error 0x8004231d: 0x8004231d)
My solution was simple.
Make sure that the size you put in the "limit to" is at least 15% of the source disk. So for example set the limit to at least 150GB on a source disk of 1TB.
Normally this should be between 15% and 20%.
