Video backup solution in the Cloud I'm about to purchase the new Macbook Pro with Retina display and I want to get the cheapest version.  But it only comes with a 256gbyte hard drive.  I probably use 30gbytes for all my data and 500gbytes for home videos (growing fast too).

Can I easily attach a USB/thunderbolt external hard drive to store my videos through iPhoto when connecting my iPhone to my computer?  Is there a good solution to then back up that external hard drive on a cloud?  Dropbox and Google Drive are amazing backup solutions, but they cost so much money as I get closer to a terabyte and they don't seem to work with iPhoto so well.

Every 10 minute video from my iPhone takes up 2gbytes, this has to be a very common problem among parents...
It's awkward to have iPhoto libraries on both internal and external disks. Aperture might be a better solution or you might want to just manage your videos outside of iPhoto instead.

Crashplan has some inexpensive unlimited backup plans available. It also can do additional backups to another local machine or locally attached hard disk.

My personal practice is to have a local backup and a remote backup using two different technologies so I use Time Machine locally to a Mac Mini that's my home server (although a Time Capsule or local hard disk would work just as well) and Crashplan for remote backups. Having a local backup is much more convenient so the remote is strictly for major disasters.
