Is there a way to make a portable iOS backup? I'm travelling and will probably get a new iPad (actually an iPad Pro - woo hoo) while I'm away. Is there a way to backup my current iPad, take the backup with me, and then when I'm near a laptop or family computer restore my current iPad backup to the new iPad?

And for those of you that are going to suggest iCloud backup, my iPad chokes everytime I try to do an iCloud backup and never completes. 

Any ideas?

Thanx in advance for your help!
I'm going to posit this as an answer.
Though I've never tested it 'in anger' it does work after a migration, so might work on a simple 'file copy'…

Your iTunes 'iDevice' backup is stored in ~/Library/Application Support/MobileSync/Backup
so in theory, carrying that to another Mac ought to allow a restore.

The untested part of my theory is whether or not the iCloud sign-in &amp; encryption factors are also contained within that structure. The sign-in, presumably will just ask you to confirm with your ID &amp; password, then check against Apple's servers, but the encryption [assuming you use it to preserve your passwords etc in the backup] is another factor.

All I could suggest would be to test before it becomes critical - if you have another computer to test with, or even on a new, 'blank' Mac account, before you go away.
If it failed at that point, you'd have your 'real' backup at hand.

As the saying goes, a backup strategy is only as good as your ability to restore it.
