You can locate the backups folder by opening the game, clicking on "Singleplayer", select a world, and then click "Open Backups Folder". There'll be a folder containing all the backups the game has created for you.
Choose the backup file you want to restore to, copy it, go to the folder above, and then open the folder named "saves". Paste the file here. Right-click on it to extract it. The backup will now appear in the world selection screen.
This bug tracker is not for help though. If you need further assistance, try the Minecraft forums.
