game saves are getting corrupted,Everyone back up your game saves

After what just happened to a friend I am advicing everyone to make back ups of you game saves.I was just in coop with a friend on smugglers compound,his Xbox locked up and when he restarted everything the game told him his file was corrupt.he dashboarded and checked his blacklist folder and sure enough,hos game save was corrupt.this poor kid,had most of the campaign done.all coops and multiplayer level was 20.

AGAIN BACK UP YOUR SAVES IMMEDIATELY AND FREQUENTLY
