I am using Windows 7 operating system and my browser is Opera 10. I had kept my system unused for a long time. So, now I thought of making a backup of my system onto my external HDD. The backup status was almost completed. But, in the end I got a Windows 7 backup error 0x8100002F with a notepad with something written as myname\downloads. I tried doing the backup again on the external device and also on some DVDs, but no use. It is still giving the same error. Someone with knowledge about this, kindly tell me why this error has occurred and what is a recommendable solution for it.
