Is It Illegal to Make Backup Copies of Games You Owned and Were Stolen?

I've owned a large number of Xbox 360 games all of which were stolen from me. I don't have the money to replace them either. So is it wrong as well as Illegal to make backup copies of xbox 360 games you owned and never gave away or sold that were just simply taken?

Suggestion:

Under law you can make a backup copy of you games but you can't give it to any one. But still a burned xbox game wont play on an xbox 360 with out a mod chip
