@jameinel did a long post on the manual steps to restore in a disaster recovery scenario:

Manual steps to Restore a Backup

They mostly revolve around the fact that the restored controller needs to change its identity to that of the old controller, which may be a different machine agent. This should be an appropriate set of steps to test out taking a backup that was created from an HA controller, and restoring it on a newly bootstrapped controller. The steps are …

We also have work on our roadmap this cycle to improve the restore mechanism.

What type of restore scenarios are you interested in?
