About station save

A single file defines a station database: file:~stations/{name}/config.bog. This bog (Baja object graph) file contains the collection of station components in an HSQL relational database management system. This database offers a fast response time in an embedded environment.

The config.bog is required to boot a station and manage its components. A station save differs from a local or system backup in that a station save backs up the config.bog to a local destination. A local or system backup saves the data collected by the system to the Supervisor PC.

Data storage in a controller is limited compared to the storage available on a PC. Each time you save a controller station, the system makes a copy of the config.bog in the controller’s memory. The save station job can also compress the HSQL database to remove empty space (requiring less memory and improving performance). This de-fragmenting of the database requires time, and may or may not be needed depending on how you use the system. You can enable and disable de-fragmentation as part of a station save. You can also manually initiate a station save with de-fragmentation.
