Use SQL replication to transfer the records to another system and backup from that. Do not perform intensive queries on a live system. It also sounds like you might be using MyISAM for radacct, if you are convert it to InnoDB ASAP.

Yes you can use buffered SQL to protection against temporary DB outages. But only for Accounting. Don't try this on 2.1x branch, use 3.0 if you want something that actually works reliably...

Yes you can use redundant to fail open or closed, but its simpler to just:

sql {
	fail = 1
}
if (fail) {
	update control {
		Auth-Type := 'Accept'
	}
}

or

if (fail) {
	reject
}
