Back Up To An External Drive
- On your external hard drive, create a new folder where you want the backup to go. Name it something you’ll remember, like “iPhoneBackup.”
- Open a new Finder window, then tap Command+Shift+G. Enter this in the box that pops up ~/Library/Application Support/MobileSync/ then find the folder named “Backup.”
- Copy the “Backup” folder to the folder you made in Step 1. Then, rename the original Backup folder “Backup-Old.” If you need to conserve space, you can delete the “Backup-Old” folder once you verify your backups are working in iTunes.
- Launch Terminal and type in the following command, replacing the “ExternalHardDriveName” with the info for your external hard drive:
ln -s /Volumes/ExternalHardDriveName/iPhoneBackup/Backup/ ~/Library/Application\ Support/MobileSync
- Go ahead and open up iTunes, connect your iOS device, and back up your iOS device as you normally would. The backup file should now be on your external hard drive.
