It's probably your gitlab services are went down. While restoring a gitlab backup we need to stop these two services (unicorn & sidekiq) 
alone, and rest of your gitlab services should be running, and then you can try restoring your backup once again. You can manager your gitlab 
services (to start, or stop, or to check stats) using gitlab-ctl command as shown below

gitlab-ctl stop [service_name] (to stop a gitlab service)

gitlab-ctl status (to check the status for all gitlab services)

gitlab-ctl start (to start all gitlab services)

gitlab-ctl start [service_name] (to start a particular gitlab service)
