Maybe a second table for radacct_historical_data would be suitalbe?
Move the data to the historical table and then delete it from your
working radacct table.

You need a sub-select

SELECT * FROM (SELECT username, sum(acctinputoctets+acctoutputoctets) AS
total FROM radacct GROUP BY username) AS foo
radius-> WHERE total > 3221225472;

Well I'd suggest triggers which get fired on updates on the radacct
table, which update a separate table with username, month, and data
(plus whatever else you need to keep on a monthly basis). Your trigger
would have the benefit of being fired automatically rather than relying
on human intervention. Or you could use cron, and have an external
script which checks the db regularly, and massages the data according to
your needs.
