On iPhone, don't backup videos in a video app to iTunes I've got a video app, AVPlayer, on my iPhone. When I put videos in there, and then sync and backup to iTunes, the videos are also backed up. This can take up a lot of time and space to backup those videos. 

How can I instead skip backing up files in AVPlayer specifically? The app, in fact, has a setting to disable backing up to iTunes, but the setting doesn't work for me because I've already got it disabled. Is there a way to control this myself, so that this app and its contents are not backed up to iTunes?
On your iPhone go to Settings -> General -> Storage &amp; iCloud Usage -> Manage Storage -> . Here you have Backup Options and you can select which apps to include in the backup.
