How to Move your iPad Backup to an External Hard Drive


Post taken from:  oxdaily.com


Note: Moving the iTunes iPhone/iPad/iPod backup folder to another drive requires that external drive to be connected in order to backup or sync future iOS devices properly.

  • From the Mac OS X Finder, hit Command+Shift+G to bring up the “Go To” window, type the following directory in:

~/Library/Application Support/MobileSync/

  • From this folder, copy the “Backup” folder to a new location on the external harddrive, for the sake of this guide we’ll choose a folder called iOSBackup on a drive named “External”
  • Before trashing the origin folder, rename the existing Backup folder to something else for backup reasons, like Backup2
  • Now we need to create a symbolic link between where the original Backup folder was, and the new location on the external drive. Launch Terminal and type the following command, referencing your new backup location:

ln -s /Volumes/External/iOSBackup/ ~/Library/Application\ Support/MobileSync/Backup

(That command needs to be on a single line, formatting may look otherwise.)

Verify Symbolic Links
To double-check that the symbolic link has been created, open ~/Library/Application Support/MobileSync/ in the Finder and look for the Backup folder, it should now have an arrow on the corner representing the symbolic link (think Aliases in terms of Mac OS X Finder), like the picture below:


Prevent Automatic Syncing of iOS Hardware
Next you’ll want to disable automatic syncing of your iOS devices, because there are probably times when you’ll be plugging iOS hardware into your Mac without the external drive connected. Doing this is easy, just open iTunes > iTunes Preferences > click on “Devices” and then select the checkbox next to “Prevent iPods, iPhones, iPads from syncing automatically”


Test a Backup & Remove Backup2
Finally, before removing the “Backup2? folder and saving the disk space, you’ll want to complete a backup and sync of your iOS device to verify that everything is working as intended. There shouldn’t be any problems, but if there are, retrace the steps to make sure everything was done correctly. If the backup is fine, go ahead and remove the Backup2 folder and you can rely on the link to the external drive when it is connected.

That’s it!

Can I undo this? How do I move the iTunes Backup back to its default location?
Yes of course! If you ever want to undo this, simply remove the “Backup” symbolic link (the one with the little arrow icon) from ~/Library/Application Support/MobileSync/ by deleting it, and then moving your iOSBackup directory from the External Drive back to its original location. It’s that simple.

Will this work for all iOS devices?
Yes it should work fine with any iOS device including the iPhoneiPad, and iPod touch. If you use multiple iOS devices, they’re all stored in the Backup folder, which could make this tip even more useful since more backups = more space taken up locally.




Hardware: iPad 2 WiFi/3G
Interaction: finger, Griffin Stylus, Adonit Jot Pro
Export/Share: Email, iTunes, iDisk, WebDAV, DropBox, Evernote, FTP, Google Docs

PDFpen from SmileOnMyMac, LLC joins a small collection of PDF annotation apps like iAnnotate PDF and PDF Expert that allows a user to import PDF files, annotate them on their iPad and share them through a variety of popular web services.

The user selects from six basic markup tools: highlight, free hand, shapes, underline, strikethrough and squiggly underline.  Once the appropriate tool has been selected the user can brush their finger or stylus along the word they want to annotate.  I found most of the tools to be pretty intuitive, once you select it all you need to do is drag your finger/stylus across a word and it will be properly marked-up.  Sadly, the finger seemed to be the best tool for this, with the Griffin Stylus coming in a close second.  The more expensive Adonit Jot had some issues, but I think that was because the app was designed for a ‘larger’ capacitive footprint and the appeal of the Adonit Jot Pro was that it has a fine point of contact.

PDFpen falls apart when a user wants to use the free hand tool to scribble notes on the pdf.  While suitable for signatures I found it very difficult to write a small note.  As a teacher, this would not be a suitable for writing feedback directly on a student’s paper.  While you could create a textbox with typed-text in it and drag in an arrow pointing to a highlighted section of the pdf the lag time to do this was pretty noticeable.

Smile Software has the potential of offering a fantastic app.  PDFpen shares documents through a wide-range of popular solutions, namely DropBox, Evernote and Google Docs that would integrate nicely into our school’s iPad 1:1 program but for the hefty $9.99 price tag I couldn’t justify making this a required app for my faculty.


Converting .acsm files into .epub


Our summer reading was the Blessing of a B Minus by Wendy Mogul.  I bought the book from Google books  for $10.99 in what I thought was the .epub format for use on my iPad, however when I got it it was in the .acsm format.  This is used by Adobe Digital Editions to send the activation ID to the delivery server which will use that ID to generate an encrypted PDF or ePUB eBook, which is then downloaded to your PC.  In short…I was able to open the book, but only via the Google Book reader.  So this is what I had to do…

I downloaded the free Adobe Digital Editions software and opened my digital purchase there.  I was then able to download the actual .epub format (it was stored in the folder ‘My Digital Editions” within “My Documents”) and import it into Calibre, my book server.  From Calibre it was an easy task to download my new book right to my iPad wirelessly.
