Leaflet Maps Marker Pro allows you to backup and restore your settings:
This makes it possible to quickly switch between different plugin profiles which makes it easier especially for users who want to deploy the plugin with custom configuration on multiple sites.
Backup of marker and layer maps is also on the roadmap for a later pro release (as I also plan to add an import feature which takes more time in developing).
