108 Chapter 8 Backing up and restoring Norstar data
N0004999 01
Either of these files could be used to restore the programming to a Norstar system through a
scheduled or manual restore in the event of complete programming loss.
When you perform a backup, the Norstar system being backed up may slow down, but it remains
operational. We suggest that you perform these operations during non-business hours, and warn
the customer that the Norstar system will be slow. The amount of time it takes for a backup
depends on the size and configuration of the Norstar system, and the baud rate the ICSRT
computer uses.
You can schedule a backup to run every day, every 7 days, every 15 days, or every 30 days. The
job then runs at the time you have chosen for whatever time period you chose. For instance, if you
chose every 7 days, the backup for that system would occur at the same day every seventh day.
To determine if any backup or restore operations have been scheduled, have run successfully, have
failed to run, or are running, view the Jobs in Queue screen. This screen allows you to remove
scheduled jobs and to view the current status of a scheduled job. Refer to
“Understanding the job
queue” on page 113.
Restoring data with ICSRT
When you use ICSRT to perform a scheduled restore, you indicate the path to the backup file on
your computer. When the restore occurs, the information from the indicated file is uploaded to the
Norstar system, replacing the existing programming.
If you use the Backup Restore tool to perform a manual restore, ensure that the file in the backup
folder that you indicate is named FNVRAM.new.
You use the Restore feature when the Norstar system has lost all its programming. During the
restore operation, the Norstar system is put in maintenance mode for the duration of the restore
process.
Setting up a restore: You can either use the Add/Submit Job screen, located under the Scheduler
menu heading (
“Scheduling backups or restores” on page 109) or you can use or the Backup
Restore tool, located under the Run Tool menu heading.
Tips: If the computer you are using is in the same building as the Norstar system, we
strongly recommend that you copy backup files to CD and store it offsite.
Caution: If you use both scheduled and manual backups for a system, ensure that you
picked the latest backup file to restore, unless you have a specific reason for wanting to
restore an older version.
Warning: After a restore process is successfully completed, you must wait at least 10
minutes before attempting to make another on-line connection to the Norstar system to
which you just restored data.
