Cannot access the Volume Shadow Copy Service

I have backups scheduled using Windows Task Scheduler, but I receive this error every time a backup tries to run:

Cannot read file "E:\Backup\FreeFileSyncSettings 2014-02-03-093700.log".

The file is locked by another process:
Folder Comparison and Synchronation, "C:\Program Files\FreeFileSync\Bin\FreefileSync_x64.exe

Cannot access the Volume Shadow Cory Service.

Error calling "fut->QueryStatus".
HRESULT: 0x8004230f, Facility: COM/OLE Interface Management Volume "\\?\E:\"

0x8004230f is VSS_E_UNEXPECTED_PROVIDER_ERROR. The best solution is to exclude "FreeFileSyncSettings 2014-02-03-093700.log" from sync via the filter.

Don't you (usually) want to exclude *\*.log ?

excluding *\*.log worked! Thanks!
