I found the fix for this, which it appears no one has in reading all the comments on other similar posts. This occurs if you have a USB drive connected and mounted as a drive. part of this code emulates a raw drive and will simply fail if you have USB connected and mounted. Dismount the usb drive and run these commands to reset your vss. (from elevated command prompt)
Net stop vss
Net stop swprv
​cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 ole32.dll
regsvr32 oleaut32.dll
regsvr32 vss_ps.dll
vssvc /register
regsvr32 /i swprv.dll
regsvr32 /i eventcls.dll
regsvr32 es.dll
regsvr32 stdprov.dll
regsvr32 vssui.dll
regsvr32 msxml.dll
regsvr32 msxml3.dll
regsvr32 msxml4.dll
net start swprv
net start vss

ignore errors if you get a few, so long as the vss and swprv start. Now try the backup again without the mounted USB. If you must use a USB drive, be sure and check "mount volumes as removable media" this way it wont interfere in the future.
