[rabbitmq-discuss] Backing up persisted messages

I can see that if a per-queue message ttl is set, messages in RAM get
deleted after the timeout.

But what happens if there are a lot of messages in the queue and they have
been overflowed to disk? Is that garbage-collected, or does it just fill up?

How does this interact with message persistence?
