My new iPhone X is beautiful, a bit too expensive for what it offers but… what the heck. It’s a nice toy. Fancy one. Yet, something annoys me each time I sync my phone with the iTunes. I do this mostly for syncing music from my library. Each time I press the sync button, a backup is also initiated and, although it is only incremental and it does not take too much time (first backup takes forever, though), I want to have control over this and be able to enable or disable the feature whenever I want.

It seems there is no way to disable this automatic backup from iTunes. There is a simple solution involving mac defaults command.

Open a terminal and write this:

[debugger]
defaults write com.apple.iTunes DeviceBackupsDisabled -bool true
[/debugger]

Check entry ok:

[debugger]
defaults read com.apple.iTunes

{
DeviceBackupsDisabled = 1;
}
[/debugger]

Restart iTunes. You’re done. Of course, if you need to reactivate automatic backups, you just type:

[debugger]
defaults write com.apple.iTunes DeviceBackupsDisabled -bool false
[/debugger]
