How to take backup of iPhone or iPad on External Hard disk

iPhone_Harddrive

Got an iPhone or iPad with low Internal Memory, No worries, We have a solution for you. Transfer all your Data to External Hard Disk. It’s not very hard, but what you may need is to understand or have knowledge of some Basic Commands.

Basic Requirement

  • USB Cable preferably USB 3.0 for fast Transfer
  • External Hard Disk / Laptop
  • working knowledge of the command line and directory structures

Step by Step Procedure for Data Transfer

  1. Quit iTunes if you haven’t done so already
  2. Connect the external hard drive to the Mac if you haven’t done so already, then create a new folder on the drive (or partition) to dedicate to the iTunes backups. In this example, we’re creating a folder to store the backups called “iTunesExternalBackupSymLink” so that it’s purpose remains obvious
  3. Open a new Finder window, then hit Command+Shift+G and enter the following path:
    ~/Library/Application Support/MobileSync/
  4. Locate the folder in this directory called “Backup” and copy that to the folder you just made on the external drive (in this example, the folder called ‘iTunesExternalBackupSymLink’ )
  5. Back in the original location of the Backup folder (at ~/Library/Application Support/MobileSync/), rename “Backup” to “Backup-Old”, or simply delete it – only do this after you have copied this folder to the external drive
  6. Now launch the “Terminal” application, found in /Applications/Utilities/ and type the following command, changing the names of your external drive and folder as appropriate ,then hit the return key:
    ln -s /Volumes/FileStorage/iTunesExternalBackupSymLink/Backup/ ~/Library/Application\ Support/MobileSync
    In this example, the external hard drive is named “FileStorage”, and the iTunes backup folder on that volume is ‘iTunesExternalBackupSymLink’, so adjust those as needed for your situation
  7. Quit Terminal, then confirm the symbolic link was created by returning to “~/Library/Application Support/MobileSync/” in the Finder, the “Backup” folder should now be a generic file with an arrow on it, signifying there is now a direct link between that “Backup” and the location specified on the external hard disk.
  8. Open iTunes and connect the iPhone, iPad, or iPod touch to the computer as usual, select the device within iTunes, select ‘This Computer’ as the backup location (optionally encrypting the backup), and then choose “Back Up Now” to start the device backup to the external drive.
  9. When the backup has completed in iTunes, double-check everything is in order by going to the folder on the external drive and confirming there is a “Backup” folder containing a hexadecimal named subdirectory – this is the backup made from iTunes of the device

For Advanced Users 

Use the following commnds

mkdir /Volumes/ExternalFileStorage/iTunesDeviceBackups/

cp ~/Library/Application\ Support/MobileSync/Backup/ Volumes/ExternalFileStorage/iTunesDeviceBackups/

cd ~/Library/Application\ Support/MobileSync/

rm -r Backup/

ln -s /Volumes/ExternalFileStorage/iTunesDeviceBackups/Backup/ ~/Library/Application\ Support/MobileSync/

Once the symbolic link has been created, open iTunes and start the backup as usual.
