I keep copies of all of my files online using a distributed storage grid that we've created.

(bias alert: I'm deeply involved in the project I'm about to mention)

A few years ago I realized that I'd either lost data due to hard-drive crashes or mistakes and wanted some sort of safe place to put my data. We then started a project (http://allmydata.org) which provides for a decentralized, secure storage fabric. You can create your own grid if you'd like, create one with friends, or use our managed grid (for a service fee).

I think that Amazon S3, Nirvanix, and others are starting to provide nice basic services in this area as well, but I do think there is a lot of room for retaining and saving information that is gently locked into web services (Flickr, blogs, LinkedIn, etc.).
