11.4.1 Archive Historical Data
The Micro-PWC can be configured to collect data from an instrument database and place it in the Historical
Database. Eventually, the collected data is aged out of the Historical Database and the disk space it occu-
pied is overwritten by new data.
Data collected in the Historical Database can be preserved by placing it (archiving it) onto a tape cartridge.
A set of data is configured to be archived by creating and scheduling an Archival Group, through Archival
Group configuration, as described in the Micro-PWC Configuration Guide.
Historical Database points are then assigned to a configured Archival Group through Historical Database
Point Configuration (as described in the Micro-PWC Configuration Guide). Historical Database points are
the assigned to a configured Archival Group through Historical Database Point configuration (described in
the Micro-PWC Configuration Guide). Then, at the user-configured cyclic interval, a message will be
broadcast, indicating that the data for an Archival Group is ready to be archived.
The message will be displayed on the operator message display area at the bottom of the Mini-Alarm Win-
dow. The operator archives the data to a tape cartridge. The data will remain in the Historical Database
only for the configured retention span. If the data is not archived to a tape before the expiration of the
retention span, the data will be lost.
To archive historical data, select Menu > Utilities> Archive Database > Historical. The Historical Database
Archive window (shown in
Figure 11-16 ) will open.
