Many companies offer unlimited online backup space for a fixed price (mozy.com, twitter.com/allmydata, onlinestoragesolution.com, etc), but they either use proprietary non-Linux-friendly software and/or have gone out of business and/or don't actually work.
Who offers reliable unlimited online backup space for a fixed price that's compatible with rsync, FTP, or other generic/open source file transfer protocols?
Or, has anyone written software that lets me treat Mozy's/etc space as though it were regular file space (eg, "mozyfs"?)
