GitLabHQ Backup and Restore procedure

First stop the GitLabHQ server, I'm using Upstart to monitor/manage the processes. It'll be different for you if you're using another process managing tool likt inittab, god or bluepill.

sudo stop gitlab

Next, be sure to remove the sqlite database and all the repositories for it to properly restore back from a backup.
