I have a windows 7, 64 bit OS, with a SP 1. I'm trying to use my windows action center to complete the back up. I'm trying to backup my documents and libraries, etc. to a disc in the D drive. Every time I try the backup it gets half way done and then gives me the error message: "Windows backup did not complete successfully" Does anyone know what setting or what has to be changed in order for me to be able to successfully complete a backup? I've never had one be successful since I've gotten my laptop over a year ago.
