Looking for a secure digital archive
When it comes to data, I’m a pack rat. I’m one of those people who has an archive of all mails since pretty much the first day I had an e-mail address. Now that we’re putting more and more stuff into the cloud, it’s getting increasingly hard to keep this up.
I’ve been looking for a way to collect and archive my data from social networks, online services (such as Flickr) but also things like e-mail, Google Docs and regular files.
Backupify comes close, but when we’re combining this much data, I’d love to have a bit of privacy. The idea of turning over all my private data to yet another service  doesn’t appeal to me all that much.
Spideroak nails the privacy aspect but only seems to be doing files. In their model, it is completely impossible for them to read your data, as you are the only person holding the key (unlike Dropbox).
Anyone has some suggestions of a digital archive that is capable of combining files/folders and online services? On-site or off-site doesn’t matter, as long as it gets the privacy right. Bonus points if it has full-text indexing and search.

 Considering how even a giant like Sony screwed this up, I do not consider privacy a nice-to-have luxury anymore.
