In reading your Microsoft Answers thread I see you're trying to backup to DVDs. I would respectfully suggest a better course of action is to backup to another hard drive. I believe most on this forum prefer a USB external HDD. DVDs have a less than desirable track record for reasons such as burn speed, DVD preference (-R, +R, -RW, +RW), and the probability of having to burn multiple DVDs, any one of which could be a bad burn and render your backup unusable.
I've used the native Windows 7 backup utility many times without any problems. You may also have damaged or corrupt system files. Run a System File Checker scan from an elevated command prompt (Option Two, this tutorial.) If any problems are found run the scan 3 times rebooting in between each scan.
SFC /SCANNOW Command - System File Checker
If you still have problems you may want to start a new thread so more people have a chance to respond.
