Archiving your database
The system prompts you (by way of an alarm) to perform a specific archiving function for Badge
History, Alarm History, or Operator History when the primary table for that history reaches 95 percent
capacity. At that time, the system takes the records stored in that primary history table and moves
them to a temporary history table. When an archive is performed for a particular history, it uses the
information in its temporary table; that way, the primary table is free to start collecting new
information right away.
If an archive is not performed before the primary table 95 percent capacity again, the data in the
temporary table is overwritten, and the original archive data lost. It is therefore important to perform
the indicated archive when the system notifies you through an alarm.
Since the time needed to reach a history threshold varies with activity levels, it is hard to predict
when a particular threshold is reached. A Force-Rollover option exists, therefore, which allows you to
archive data on a regular schedule, such as once a week. This task can then be incorporated into
your normal backup procedure. The Force-Rollover option takes data in the primary table and
transfers it to the temporary table even if the primary table is not full. The Force-Rollover option only
displays on the Backup window if the data currently in the temporary table has already been
archived. This prevents un-archived data from being erased when new data overwrites it. (This data
will, however, be overwritten when the primary table becomes full.)
Note:
In Picture Perfect 4.1, in addition to the Archive Notice pop-up, an alarm is triggered to notify that it is time to
perform an archive.
