How to Backup an iPhone to External Hard Drive with Mac OS X

http://osxdaily.com/2016/03/04/backup-iphone-to-external-hard-drive-mac/


--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.  // :)
((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.))

--Open a new Finder window, then hit Command+Shift+G  [or select Go fr menu top of screen .. Go to Folder]  and enter the following path:               //yes good this path works//
~/Library/Application Support/MobileSync/
Locate the folder in this directory called “Backup”   //yes got it// and copy that [the Backup folder] [in]to the folder you just made on the external drive (in this example, the folder called ‘iTunesExternalBackupSymLink’ ).

--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.  

--Now launch the “Terminal” application, found in /Applications/Utilities/ and type the following command,
changing the names of your external drive [ie FileStorage change to Seagate or whtvr] and folder [iTunesExternalBackupSymLink to maybe, iPhoneBackupbyiTunes or whtvr]as appropriate,then hit the return key:
ln -s /Volumes/FileStorage/iTunesExternalBackupSymLink/Backup/ ~/Library/Application\ Support/MobileSync

/// so that creates the symbolic link   fr orig Backup folder on internal harddr ~/Library/Application Support/MobileSync   to the Backup folder now within the dedicated folder [for me, maybe named:  [iPhone6sBackupbyiTunes']

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

-->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   << bcs 'this computer' = backup fldr wh will link to the folder on the ext harddrive!

When the backup has completed in iTunes,
--confirm 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


That’s all there is to it. As long as the external hard drive is connected to the Mac, iTunes will now backup to that external storage volume rather than the internal hard disk.
//and as long as connected, can restore fr there using itunes.

// For this the ext hard drive shld be formatted Mac OS journaled right?  seems clear, since that is wh the mac (internal hard dr)  is, wh is where usually backing up to.

context fr beginning article:
you’ll need some working knowledge of [well, just need follow your instrxns re] the command line and directory structures, since we’ll be using symbolic links to get this done.   "symlink"
