Hidden / read only nodes or other real-time replication mechanism

What’s the current best practice for real-time backups outside of the production cluster? I’ve read through some other topics on this group but I haven’t come across any consensus or any practice that seems particularly feasible.

Off-site, real-time backups are essential. Are there any tools that allow us to do that with Event Store?

You could easily do this yourself by subscribing to the cluster and writing the events yourself to another node.
