I worry about what will protect the data from being lost period if something happens (God forbid) to you or your home. In "the biz" we like to say that a backup in the same physical location as the master is no backup at all. I'm still baffled as to why it's so critical to you to keep this data hidden from the community, but if you're intent on doing so, wouldn't it at least make sense to send a copy of everything to someone else here that you trust (Moncha perhaps?) so there's at least some way to recover?
