accounting to local and remote server

[d tbsky]

hi:
    I need to setup proxy for a realm, and sent accounting to remote
radius server.
but I want to keep a copy of accounting data at local radius server too.

   after searching the email list, I found strategy below:

 1. create two detail file
 2. use buffered-sql  to write data to local sql server
 3. use copy-acct-to-home-server to sent data to remote radius server

is the above strategy correct? or there are better ways?
thanks a lot for help!!

Regards,
