The basic flaw, to me, seems to be your erroneous assumption that the
enemy has symmetric compute capability to yourself.  Once you give
the enemy a copy of your data, even if it is encrypted, you are
opening the door to them using some hyper-core, quantum-cooled super-
fandango against your crypto, and you give them all the time in the
world to do it.

You cannot decrypt what is not encrypted.
No one said you have to play fair on the grounds of security.

So, I think this is a dumb idea... :)

Also, you will only have available, in the cloud-solution you offer,
archival copies of the data.  The latest versions will only be on
your machine.

While SSH datastreams might be captured and eventually decrypted, the
attacker must have access to your wire.  If you post your datastream
all over the net, they don't need that.  SSH also provides access to
live data and is already available on many platforms....
