Per https://github.com/gitlabhq/gitlabhq/commit/7c54c63ac14eb8f5ce0e364d709988fcfe4dda64

In my case I had to create satellites before everything worked correctly and it is just good practice to check gitlab after doing a restore.

Also warn users about the yaml formatting, see
https://gitlab.com/gitlab-org/gitlab-ce/issues/874

Users need to backup SSH keys if they want to do a complete restore to the same domain and not have users get the `WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!` and man-in-the-middle attack warning messages. Related to https://github.com/gitlabhq/gitlabhq/pull/8359.
