A full year free, and its a really good service, I'm using it right now because of the promotion and am loving their encryption they provide to their users. It's really, really strong 448-bit plus you can use you're own key too for another 448-bit layer on your data.
CrashPlan+ gives you unlimited file storage for one machine for free a year or 2-10 computers for a reduced $50 during this promotion.
And they let you backup to your friends computers for free if you ever want to do that too. Like, have a system that's always up as another way to backup in addition to the cloud.
Uh, and you can pick individual files to backup. Make sure you adjust the software settings, because it is an automatic backup software. If it's a one time thing you're doing, set the schedule to something that isn't "Daily" unless you want it to daily upload changes to your videos.
Hope this helps
