    I had to successively backup half my files at a time, each time one half would fail with this error. I then took half of the failed directories and ran backup – half would fail. I continued to successively select half of the failed directory tree. Eventually I isolated a hidden folder containing cookies. When I tried to find this folder using explorer, it wasn’t there, but when I did a search for ‘cookies’ the folder showed up. I deleted the folder and all the cookies in it. Then I was able to backup my entire system without the error. FYI – the folder was: R:UsersPaulAppdataRoamingMicrosoftWindowsCookiesLow I removed the Cookies folder and all its files and subdirectories.

    Thanks for your comment Shiff.

    All sites where solutions are discussed are saying “remove all the reparse points”, but there are no explanations _how_ to do that!

  4. Nik says:

    Reparse points are basically data paths that you have configured for backup.

    @Nik: You still didn’t answer Rasp’s question: *how* do you remove reparse points? How do you even determine what they are? Basically, can you elaborate on the *exact* steps to take.

    Make Sure the Virtual Disk Service is not disabled and is running.

    I disabled Microsoft Security Essentials and the backup completed.
