Ask HN: What do you use to backup your data / family photos?

I have a ton of videos of my family, pictures I would regret losing. I also have a lot of books and documents on my desktop.

What do you use to manage backups? I'm looking for something that backs up everything, and also let's me browse the backed up data in a browser or something.

Dropbox seems nice, but $100 is a little steep if I can find something a bit more inexpensive.

What do you use?
