Long story short, my parents went to Europe and took lots of pictures. When they came home and connected it to the PC it said 'backing up' for around 15 minutes but after that the photos on the iPad were gone. I located the backup files in XP (although they are not jpg files but generic files) so I copied those just in case. So my question is, can I recover those photos? Will 'restoring from backup' fix the problem or not?
