The production / warm standby back-end servers were automagically synced every hour. Yes, including the database.

This meant that:

1. we had a close-to-production testing server always available;

2. we had a way of quickly switching to almost completely up-to-date backup back-end server in case anything went down with the production.

The set-up on these back-ends included *two* nginx instances running parallel on different ports but with same config, serving same content.

Yes, on each.
