+1.

btw, are you having some laggy (high load avg) using yosemite?

there's a list of sites that has remote job offers here: https://github.com/lukasz-madon/awesome-remote-job

it's one server as master (write) and one as slave (read-only). you also must do backups, but using this approach it will be more safe than only backups.

later, you can setup to when one server crashes [master or slave], automatically setup a new server and copy the data.

database: maste-slave

uploads: rsync

there's a ruby gem called backup (https://meskyanichi.github.io/backup/v4/) ;)
