Log to both Local & Remote

My friend has problem when NIC LAN down, he can't receive log in syslog

I told him, I need to check whether FGT can pump log to local and remote file concurrently

After checking on GUI I can't see menu in logging that allow local and remote logging

Only either local or remote logging

If remote, I can pump up to 4 syslog server

Since pump to local & remote are impossible.

The only option in my mind is pump log to multiple remote log using multiple LAN NIC

QUESTIONS:

1. Is there possibility to store log locally and scp that local log file to syslog server

If yes where local log file stored and what filename

2. can I set local log to 1 month and create another filename for next month
