List of online storage services

A list of 90+ resources on online file storage, and many of them those "Web 2.0" style companies. I guess with recent storage associated disasters, having a good online off-site backup is high on my consideration. However, I don't need to know 90+ of them providing this service. I need to know, how many of them will still be around to restore my files, when I need them in 3-4 year time when I hard drive dies. I don't need to know features (a rsync+ssh is all I need), but is there a list sorted by reliability and longevity?
