I just bought a new MacBook Pro overseas. I currently own a MacBook Air and I need to bring a backup of this current computer to US, so I can restore it on my new computer when I arrive.

I currently do incremental backups to a Time Capsule, but bringing it is not an option. What would be the best strategy to back my data up to an external HD and restoring it later on this new MBP?

I am OK if I need paid solutions too, but of course freebies are better.
