Current Behavior or Linked Issues

Adding backup setting and parametrization of backup redundancy. As default settings are just set explicitly now - there is no impact on existing envs. MR just add a possibility to change this if needed. For example this is required for specific case when the Infra deployed in Brazil (as a main region) and default Geo replication setting is automatically make a replica outside of Brazil (in US) because Brazil is a single available region in this location so Geo replication is exceptionally including US region (according to MS documentation of paired regions and backup replication). This becomes a data residency issues for clients in Brazil that don't want to store any their data outside of Brazil.

So in this case we have possibility to change replication mode and avoid data residency issues.

Does this introduce a breaking change?

  • [NO]
