Wise folk know that two's company and three's a security risk. But some Net people, including myself, have decided that we can increase our security by sending sensitive records to complete strangers. We call it file fostering. The strangers who receive our data may be ditzes or agents of hostile governments, but that's OK, because the files are sent to more than one person and in an encrypted format. The recipients don't get a decryption key, so they are left holding an inscrutable nest egg of data. Why would someone do this for me? Because I'm prepared to do the same for them.
In the end, each of us ends up with a cross-jurisdictional, multiple-mirrored, private backup of our most crucial data - as long as we don't lose our keys.
