Add backups runbook

This is an old branch and probably out of sync.

Can you pick it up and update it?

@pcarranza I can and I will!

@ahanselka ping ?

Should I close this?

I was going to wait until I was actually able to restore successfully, which has yet to happen. We can close this and rewrite it entirely when we have more information on restoring. Is the doc in its current form accurate at all?

I seriously doubt it.

Let's close and rewrite
