I would have assumed 'sever' was actually a remote machine (for unison)
ensfc only works between local file systems. Though thay can be ANY
filesystem that could have been mounted/copied from a remote server
(dropbox, sshfs, nfs, unison, etc).
So that last should probably look exactly like the first!
Unless it being a laptop you want to keep the Documents saved in encrypted
form.
In that case ~/enc_tmp becomes the real files and you remove the reverse
The unison part however remains the same.
On a machine storing files unencrypted (order is important)
encfs --reverse ~/Documents ~/enc_tmp
unison ~/enc_tmp /server/remote_store
On machines storing file encrypted (order not important)
encfs ~/enc_tmp ~/Documents
unison ~/enc_tmp /server/remote_store
The later can do the two commands in any order.
That is you can 'sync' at any time, and unencrypt the docs only when you
make changes. In that case a remote server could be the laptop
itself
For example I have encrytped files syncing between my workstation
and my laptop.
Workstation
encfs ~/encrypted ~/documents
Laptop
encfs ~/encrypted ~/documents
unison ~/encrypted /workstation/encrypted
NOTE this this case the unison command MUST only run on one machine
(laptop in my case). I have not found how I can launch it from
either machine to sync the same to directories and have it use
teh right unison cache information.
This is probably simplest!
