Alarm Maintenance Overview

Use the alarm backup feature to maintain a backup copy of alarms when you plan a maintenance activity. Use the alarm restore feature to retrieve the alarms that have been backed up or deleted or to move alarms from one system to the other. Use the alarm purging feature to delete alarms that you do not want to store and to manage disk space better.

To backup, restore, or purge alarms, the latest Historian Administrator and Data Archiver is required. If you point the Historian Administrator to an earlier version of the Archiver, the Alarms tab appears unavailable and the option to backup only alarms is not accessible. However, the 6.0 (or later) Administrator can be connected to a pre-6.0 archiver to archive alarm data automatically with the archive.
