[Q] Data recovery topic

Hi guys....
Is there a way to undo an overwrite on a file? I've overwritten a file on my sdcard in my S5 but realized I shouldn't have.....

It all started when my game data (Google Play game data) wasn't showing up properly....I selected the save location to be the device but when I started playing this afternoon all data was gone. Now in my game I was on level 10 with 2 cars and a nice amount of cash but after this afternoon I was still on level 10 but my cars were gone and my cash....AND I had to start over (but my level was still 10). How is that possible?
Ok fortunately this morning I had made a Titanium Backup of the game and data so I should be able to restore that to this morning's status.....wrong! THAT's the backup I've overwritten with a new Titanium backup. I actually made a backup of the first Titanium backup on my SD card but with the whole confusion I copied over the new backup to my SD card, overwriting this morning's good backup......
Anyone know how to recover my good backup files?? :confused::eek:
