iTunes Does Not Back Up iPhone/iPads

When an iPhone/iPad/iPod is attached to a Windows machine, iTunes will launch and sync the device but not perform a backup. This is despite all connections seeming to be OK. Additionally, the “Backup Now” button will be greyed-out.

This may be because backups have been disabled. To reinstate the function:

1. Close iTunes.

2. Disconnect all devices.

3. Open a command prompt and type:

   "C:\Program Files (x86)\iTunes\iTunes.exe" /setPrefInt DeviceBackupsDisabled 0

   Nothing will appear to happen.

4. Reattach the devices.
