Thanks for that. I'm really worried about the whole java aspect of crash plan, so I just setup the trial for back blaze (native os x app). So far so good! It just works... I don't even see it show up in activity monitor. We'll see how my test restore goes. If that works well, fifty for the year is very reasonable and I'll just subscribe and forget about it.
Not to push you either way (I use Crashplan), but what is it about Java that concerns you? The web exploits we have seen recently relate to the Java web plugin and not the Java runtime you use for the Crashplan app. Just turn off Java in Safari and you are safe from the web Java exploits. That still allows you to tun Java applications.
A neighbor of mine is using BackBlaze and he seems happy with it.
