Subject: backups: do backups for the laptop

From the laptop I only backup /home/fcuny, as the rest should be
straightforward to rebuild with nix.

I run that backup as my own user, since I need my ssh key to use the
remote repository (which is on the NAS). I also need a new secret for
it (I might have been able to use `pass' for this, but well, that's easy
enough).

For the NAS, I update the list of directories to backup to include home,
this will be on the systems backup.
