Types of Data
The EcoStruxure Building Operation backup function enables you to back up different types of data.
The EcoStruxure Building Operation backup function provides two backup options:
Configuration only : This option makes a back up the configuration database and and is useful for new installations. Configuration data includes points, values, alarm objects, trend objects, programs, graphics, and custom object type data.
The Configuration only option also includes the configuration properties of variables, such as Unit. Depending on the retain level of the variable, some configuration properties like Value are also included in a backup. Pour plus d'informations, voir Retain Level .
All data : This option makes a back up of the configuration database and the historical data. Historical data is trend logs and event logs. The option All data is useful for existing systems,
Depending on the type of data, the system locks changes to the database while a backup is in progress in different ways. For configuration changes, the EcoStruxure Building Operation software queues up the changes until the backup completes. For historical data changes, the EcoBuilding Operation buffers the data based on the limits of the buffer size.
When you back up an EcoStruxure BMS server specifying either Configuration only or All data, the EcoStruxure Building Operation back up includes all the configuration values that are specified for the EcoStruxure BMS server’s objects. If you restore the EcoStruxure BMS server back up, the configuration values are restored, which can overwrite any changes made since the last backup. Pour plus d'informations, voir Retain Level .
When deciding on the frequency of EcoStruxure BMS server backups, you should take into account the potential cost of recreating any historical or configuration data that can change since the last backup. For example, you can perform an All data backup back up a field server weekly if multiple operators use their WorkStations frequently. As a precaution, you can perform a Configuration only backup before installing a new application or modifying the current configuration.
