Where are iPad backup files stored on my Windows computer?

The folder where your backup data is stored changes depending on the computer's operating system. Since iTunes only keeps one backup per device, you should ensure the backup folder is included in your periodic data-backup routine.
iTunes places the backup files in the following places:
•Mac: ~/Library/Application Support/MobileSync/Backup/
•Windows XP: Documents and Settings(username)Application DataApple ComputerMobileSyncBackup
•Windows Vista: Users(username)AppDataRoamingApple ComputerMobileSyncBackup
