Auto backup iPhone

I am trying to problem solve an issue with photos syncing to my phone and every time I have to test it it backs up the full 50 gig of data making this process extraordinarily long and tedious. But it seems you can disable that feature using terminal. I record it here for posterity …

If you are synchronizing to a Mac:

1. Close iTunes on your Mac.

2. Launch Terminal.

3. Type

defaults write com.apple.iTunes DeviceBackupsDisabled -bool true

and press Enter.

4. If you want to re-enable automatic backups, type

defaults write com.apple.iTunes DeviceBackupsDisabled -bool false

and press Enter.
