The root cause is error with code 2147754767 , it's a Windows error that can be searched by its hex code - 0x8004230f .
It seems that there is no universal solution, here is one of many links found by 0x8004230f . error code

And, just in case - is Volume Shadow copy ” service enabled and started?

Thanks for your response. I have discovered that if I dettach my USB disk I can execute the backup without problems.
Look at this link, resolution number 3.
