Configure the archive of purged data

  • Last UpdatedMar 07, 2025

You archive the records purged from the alarm database and then restore them using the Alarm DB Restore utility.

When you purge the alarm database, the Alarm DB Purge-Archive utility automatically creates a set of nine archive files that correspond to the purged alarm database tables. Each file contains the purged records of a single table.

The Alarm DB Purge-Archive utility assigns names to the archive files based upon the table name, date, and time when the purge operation occurred. For example, the name of the archive file for the AlarmMaster table that was purged on June 22, 2007 at 5:30 p.m. is formatted like the following:

AlarmMaster_06222007_1730.txt

To configure the archive

  1. Open the Alarm DB Purge-Archive utility. Do the following:

    1. In the Tools view, expand Applications.

    2. Double-click Alarm DB Purge-Archive.

  2. Click the General tab.
