Michael Neidig is on an extended trip and needs to replace his iPad. It normally syncs with an iTunes on a home computer. He asks:
Is there some way I can back up all my apps etc on my current iPad and then transfer them to the new iPad I purchase?
This is a superb question, as it highlights a bit of understandable confusion about what a backup is in iOS compared to, say, OS X. I’ll answer the question before providing the details: Yes, you can, but you might lose some data, depending on what you have stored on your iPad and what you want to retain.
On a Mac or another computer, when you want to back the entire system up, you make a clone or choose subset of data, like all documents and applications. Restoring a computer from scratch requires a clone, which is an exact duplicate of all the data you were using; restoring from archives, you might use an existing OS X fresh system, and then use archive software to bring in all the apps and documents you backed up.
