    name        = "test"
    description = "test"
    ordered_availability_zone_list{
        availability_zone_url = "ab788130-0820-4d07-a1b5-b0ba4d3a42asd"
    }

    availability_zone_connectivity_list{
        snapshot_schedule_list{
            recovery_point_objective_secs = 3600
            snapshot_type= "CRASH_CONSISTENT"
            local_snapshot_retention_policy {
                num_snapshots = 1
            }
        }
    }
    category_filter {
        params {
            name = "Environment"
            values = ["Dev"]
        }
    }
}

Example usage of a resource recovery plan

resource "nutanix_recovery_plan" "recovery_plan_test" {
    name        = "%s"
    description = "%s"
    stage_list {
        stage_work{
            recover_entities{
                entity_info_list{
                    categories {
                        name = "Environment"
                        value = "Dev"
                    }
                }
            }
        }
        stage_uuid = "ab788130-0820-4d07-a1b5-b0ba4d3a42asd"
        delay_time_secs = 0
    }
    parameters{}
