Hi,

Trigger this command and see if you have old snapshots? "vssadmin list shadows"

You many need to delete all the old snapshots (if found) - "vssadmin delete shadows /all"

Try attempting the backup and see if it goes fine? if the issue still persists, follow the steps;

cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 /s ole32.dll
regsvr32 /s oleaut32.dll
regsvr32 /s vss_ps.dll
vssvc /register
regsvr32 /s /i swprv.dll
regsvr32 /s /i eventcls.dll
regsvr32 /s es.dll
regsvr32 /s stdprov.dll
regsvr32 /s vssui.dll
regsvr32 /s msxml.dll
regsvr32 /s msxml3.dll
regsvr32 /s msxml4.dll
vssvc /register
net start swprv
net start vss

Copy all the commands in notepad, save it as vss.bat, run the bat as administrator (elevated command prompt).
