My windows backup has suddenly stopped working. I keep getting this message:
"Check you backup.
A shadow copy could not be created. Please check VSS and SPP application event logs for more information.
Details: insufficient storage available to create either the shadow copy storage file or other shadow copy data."
My PC hard drive is 300GB, and the extenal drive target is 2TB, with 1.74TB available. The backup has worked fine for months.
