How do I move my photos library to an external drive?

What are the step by step instructions for moving the new Photos Library to an external hard drive in able to free up space on my MacBook's drive?


I searched the forums and did not find anything related to moving the new photos library, not the old iPhoto library. A concern I have after reading through older threads is if videos will transfer over properly. I read that videos will turn into stills. I don't want to lose my videos. I plan on making a back up of my entire MacBook via Time Machine to a separate external hard drive before I even start this process at all but I want to make sure I do all of this correctly.


I have a MacBook Pro running OS X Yosemite version 10.10.3.

I will have 2 separate external hard drives. One for the MacBook back up and one for the photos library to be stored on.


Thanks!

MacBook Pro, OS X Yosemite (10.10.3)

If I understand correctly, you want to backup your iOS devices to a drive other than your Mac's (because they have small SSDs). It is possible to backup multiple Macs to a single Time Capsule.

Sadly though, it seems that Time Capsule doesn't support backing up iOS devices (yet. I really do hope this becomes an option soon, and I'm not the only one). Here are ways you can make sure those 50GB in your iPhones don't end up in your Mac's SSDs though.

Photos

In terms of pictures, iOS8 should have you backed up with iCloud Photo Library. If enabled, all your pictures and video will automatically be stored in iCloud, which gives you 5GB of free storage (or 20GB for $1/mo, 200GB for $4/mo).

If that is not your jazz though, you can always sync to iPhoto, but move the iPhoto library to an external hard drive. iPhoto stores all your photos a single archive, the iPhoto Library on your

Pictures
folder, which you can move as you please. When iPhoto opens, it will automatically look for the iPhoto Library where it last saw it, but if it can't find it it will ask you were it is, and keep working as if nothing had happened.

Backups

iTunes backups might be a little more tricky, but it seems to be possible to move the folder where iTunes stores its backups to an external hard drive, and then trick iTunes into backing up there.

I haven't tried doing this myself, but here's a post that claims you can do it and outlines the steps to follow, both for Windows and OSX. The instructions for OSX aren't too bad, as long as you aren't too scared of using the

Terminal
application (
Applications/Utilities/Terminal
). In a nutshell:

  1. Copy
    ~/Library/Application Support/MobileSync/
    to a new location, say
    /Volumes/~Your External HDD~/MobileSync
    . This directory has a folder called
    Backups
    , which is where iTunes stores backups for mobile devices.
    • Note 1:
      ~/
      is an alias computers use for your home folder.
    • Note 2: Your
      ~/Library
      folder is hidden by default. You can open it in Finder by opening
      Terminal
      typing in
      open ~/Library
      .
  2. Remove/rename
    ~/Library/Application Support/MobileSync/Backup
    . We won't need it anymore.
  3. Create a symbolic link to the new location for
    Backups
    in your external hard drive. This is basically like an alias in the old location of
    Backups
    to its new location. To do so open
    Terminal
    and type in

    ln -s /Volumes/**~Your External HDD~**/MobileSync/Backup ~/Library/Application\ Support/MobileSync/Backup

If you launch iTunes now it should follow the symbolic link and go on with business as usual, not knowing that in fact it's now working with a folder that's on an external hard drive.

You'll need to have the hard drive connected to backup,

Hope it helps!

Good morning to all of you! I want to ask what happened in my case, I have an external hdd 1tera with MS-DOS format on which I moved the files PHOTOS LIBRARY.photoslibrary containing 12GB of important files for me.

I had to do an action very fast and sudden cause my iMac died unexpectedly... now I bought a new iMac and I wanted to return the file PHOTOS LIBRARY.photoslibrary on new Mac but going to open pictures with the command options (Alt) and going to select that file as a library to open the result is: NOTHING! no photos from here... how can I recover those 12GB inside photos and videos? 😟


p.s. Sorry for my poor english

First question:


When I open pictures folder, it shows both a "photos library" as well as my old "iPhotos library". I'm pretty sure photos incorporated all the data from the iphotos library into the photos library, but I'm not sure how it all works. Do I have to copy them both? Or, once I copy the photos library, can I just trash the iphotos one. (or is there a reason it was retained in the first place?)



Paul_Adrian

Did you ever find a solution the your first question? I am looking to do the same thing as you.

If you are 110% sure you will not want or need iPhoto again then you can archive the iPhoto library and trash it and move only the Photos library - If you have space on your EHD I suggest moving both just in case you want or need the iPhoto library - but moving the the EHD does break the hard links so each will take up the full space reported
