What is Purging?
"Purging" ref ers to dele ting old
records from the message logs, to
free up additional hard-drive space,
and allow reports to run faster.
Read Me: Archiving or purging on a regular
basis is highly recommended since the
system can become slow and/or unstable if
database files become very large.
Purging can be done man ually, and
can also be set to occur
automatically.
Note: Purging pertains to activity messages and/or
panel communications and database-update logs (from
all defined accounts).
Tip: To have the data available for running reports in
the future, use the archive feature instead (previous /
above).
