It's always possible to forget it.  I could write it down on paper, but
paper is very volatile.

I'd still have to encrypt them.  Other than that, yes, maybe if I had a
database of all files telling some system that encrypts and uploads them
which files have changed, and if I had something that monitors all files
in some useful way, it may be possible.  I don't have such a system,
though, and no remote place to store files at.

Knowledge is volatile and fluid.  Software is power.
