+####start/stop
+unifi.sh is a start/stop/status script. the start script calls finally a tail -f server.log to keep the container running
+####Backup
+There is a cronjob in place calling backup_unifi.sh , which will trigger a logrotate for mongodb and afterwards
+stop the Controler to tar the unifi data tree to /backups and restart finally
+####Restore
+for restoring a backup call/exec restore_unifi.sh [filename]. filename will be expected in /backups. Without filename the last backup
+unifi_data.$(date '+%Y%m%d').tar.gz is assumed as default
