I was reading this about the iphone backup process today, and here is how you can turn off the backup function to save time every time you sync. You should probably go to zerologic first to read the full details, but below is the nitty-gritty.
This command will change a hidden setting in the iTunes preferences that will force it to skip the backup process.
This is not a Steve Jobs approved technique…
1. - Quit iTunes.
2. - Open Terminal.app
3. - Copy and paste this in, then hit return:
defaults write com.apple.iTunes DeviceBackupsDisabled -bool true4. - Open iTunes
5. - Plug in your iPhone (2.0 or 3G) and sync.
It will take a few seconds, assuming you don’t have a ton of music or podcasts.
Changing the ‘true’ in step 3 to ‘false’ will re-enable the backup feature.
