Note
When you purge data, you permanently delete it. If you want to keep data that will
be purged, back up the database.
Cisco CRS Administration provides the following features for purging historical
reports from the database:
• Daily comparison of the size of the database to a user-specified maximum
size
•
User-specified time at which the system purges data
•
Automatic purging of the database when it exceeds the user-specified
maximum sizes
• Automatic purging of the database based on user-specified parameters
• Manual purging of the database
•
Automatic e-mail notification of purging activities
•
Automatic Simple Network Management Protocol (SNMP) traps and Syslog
messages describing purging activities

Configuring Automatic Purging
The CRS Engine performs automatic purging each day at a preset time.
Note SQL Agent Job Scheduler manages purge scheduling.
To help keep your system running most efficiently, schedule automatic purging to
run when your system is least busy. By default, daily purges are scheduled to run
at 4:00 a.m. (0400), but you can change this time.
The system bases its purging activities on a variety of parameters. You can change
the default value for any parameter as needed.
