Seeking Online File Storage

Not sure if any of you who read my blog would know of a service, but I have to try. As several of you know, I am very hard on my computers - usually laptops. I go through multiple harddrives and since I left MIT which had this excellent, (though laborius to retrieve from), TSM offline backup system, I haven't really been vigilant with my backups.

I am looking for a product that is essentially an online service or Web site that will allow me to synchronize specified Windows XP folders with this online service - perhaps via WebDAV or some other protocol. I want to be able to go to a URL and individually pick and choose files "on my system" to download. Essentially a more seamless CVS system.

Should I just setup a SubVersioN server somewhere and use TortoiseSVN to synchronize?
