The only way to turn it 'off' is to cancel the backup in iTunes (pressing the 'x'). It will still go on to do a normal sync if you do so. I'm mixed about the feature. It has come in handy however a backup every time is a bit much. I'd much rather have the option to 'backup every 10 syncs' or perhaps 'backup X-times per month'.
Yeah this is an annoying "feature" that iTunes seems to have - it backs up all apps every time, and not just the newly added ones. Hopefully apple can fix this eventually to make it incremental...
Does it do this automatically for just the apps or for apps, music and video? I prefer manual sync and would hate to have automatic sync thrust upon me (I'm an oldschool control freak when it comes to my syncing, lol!)
Incremental backups or a way of choosing how often you want to back up (every time, every 24 hrs, every week, etc.) would be nice. It's a little frustrating to have to wait for full backups every time.
they just need to stick with the backups they were doing with 1.1.4. they were only took about a minute or 2. they don't need to worry about backing up apps because you can always redownload them for free if you've already bought/downloaded them.
I found that the Mobile Applications folder under iTunes folder gets bigger with this backups. Actually I have multiple instances of the same application (numbered 1, 2, 3...) even when that application haven't been updated since their first version.
I guess the sync issue is based in the fact that you can't control which application you want to be synched back to your computer. If you delete one app on the computer and also purchased a new app on the ipod, next time you sync then you'll be forced by iTunes to choose between transferring BOTH apps back to your computer, or not transferring the app bought and keep the deleted app (from iTunes) in your iPod (unless you delete it to from your iPod, which means that every time you want to delete an app you must delete it from iTunes and the iPod or iPhone).
I would prefer a little bit more control at the sync time of which application should be synched back to iTunes, or deleted from the iPod (perhaps a simple automatic sync which looks for the last action you did would do the trick) but this depends on Apple engineers .
