$SCRIPT_NAME is a small shell script that backups up a Mikrotik router

Put your settings in the config section in the script itself!

 -i                 IP address of the router
 -n                 name of file out put (example: -n thisName would produce thisName.daily.rsc or thisName.daily.backup - depending on -t option)
                    this could also include a path i.e. /tmp/thisName
