I'm trying to backup my user files and C:\ along with a system image of the C drive on to a 2TB external drive. Everything goes well right and when it completes I get an error message saying that "backup did not complete successfully" because of error 0x80070578 "invalid windows handle." I did a google search and I found an article to start Windows Backup and Volume Shadow Copy in the services, which I did. However it did not work. What else can I do to alleviate this?
