I am using Windows 7 and want to do a full system backup. I have recently tried to uninstall the program, Dropbox. The error is related to remaining Dropbox files. I have used Windows Disk Cleanup, but still cannot get the backup to copy the system backup files to My Passport external hard drive. I have used Windows system search to find the indicated file or files, but get no useful results.
Happy to report the following: I found an empty file folder in the Libraries section of the Windows contents. It had the title that was indicated with the error message 0x80070003. I removed the folder; restarted the Compaq desktop computer; attached the WD My Passport to the USB port and started the backup. The backup was completed successfully!
