Recover wrongly synced deck

Hi everyone. I was synching some of my profiles to the web server and clicked the wrong button for which data to use. I have lost about 8 weeks worth of information and have been trying to find a way to recover it. Is there anyway to like reverse something within 24 hours? I tried control Z and that didnt work. Thanks for any help
