    Abstract: Replicated instances in a database environment provide for automatic failover and recovery. A monitoring component can periodically communicate with a primary and a secondary replica for an instance, with each capable of residing in a separate data zone or geographic location to provide a level of reliability and availability. A database running on the primary instance can have information synchronously replicated to the secondary replica at a block level, such that the primary and secondary replicas are in sync. In the event that the monitoring component is not able to communicate with one of the replicas, the monitoring component can attempt to determine whether those replicas can communicate with each other, as well as whether the replicas have the same data generation version. Depending on the state information, the monitoring component can automatically perform a recovery operation, such as to failover to the secondary replica or perform secondary replica recovery.

    Abstract translation: 数据库环境中的复制实例提供自动故障转移和恢复。 监视组件可以定期与实例的主副本和副副本进行通信，每个实例可以驻留在单独的数据区域或地理位置以提供一定程度的可靠性和可用性。 在主实例上运行的数据库可以将信息在块级别同步复制到辅助副本，以便主副本和辅助副本同步。 如果监视组件无法与其中一个副本进行通信，则监视组件可以尝试确定这些副本是否可以相互通信，以及副本是否具有相同的数据生成版本。 根据状态信息，监视组件可以自动执行恢复操作，例如故障切换到辅助副本或执行辅助副本恢复。

    Abstract: The values of various operating and/or configuration parameters of a data environment are managed using a set of self-service Web services and interfaces of a separate control environment. A customer can submit a Web services call into an externally-facing application programming interface (API) or other such externally-facing interface of the control environment. The API receiving the call, as well as information extracted from the call, can be used to determine appropriate adjustments to be performed in the data environment. A workflow can be instantiated that includes tasks used to validate and/or apply the adjustments to the target resources, such as databases, data instances, data stores, instance classes, etc. Various real-time functions such as monitoring and auto-scaling also can be performed via the control plane.

    Abstract translation: 使用一组自助Web服务和单独控制环境的接口来管理数据环境的各种操作和/或配置参数的值。 客户可以将Web服务调用提交到面向外部的应用程序编程接口（API）或控制环境的其他面向外部的界面。 接收呼叫的API以及从呼叫中提取的信息可用于确定要在数据环境中执行的适当调整。 可以实例化工作流程，其中包括用于验证和/或应用对目标资源（如数据库，数据实例，数据存储，实例类等）的调整的任务。还可以进行各种实时功能（如监视和自动缩放） 可以通过控制面进行。

    Abstract: A network-based services provider may reserve and provision primary resource instance capacity for a given service (e.g., enough compute instances, storage instances, or other virtual resource instances to implement the service) in one or more availability zones, and may designate contingency resource instance capacity for the service in another availability zone (without provisioning or reserving the contingency instances for the exclusive use of the service). For example, the service provider may provision resource instance(s) for a database engine head node in one availability zone and designate resource instance capacity for another database engine head node in another availability zone without instantiating the other database engine head node. While the service operates as expected using the primary resource instance capacity, the contingency resource capacity may be leased to other entities on a spot market. Leases for contingency instance capacity may be revoked when needed for the given service (e.g., during failover).

    Abstract translation: 基于网络的服务提供商可以在一个或多个可用性区域中为给定服务（例如，足够的计算实例，存储实例或其他虚拟资源实例）预留和提供主资源实例容量，并且可以指定应急资源 另一个可用区域中的服务的实例容量（不提供或预留用于独占使用服务的应急实例）。 例如，服务提供商可以在一个可用性区域中为数据库引擎头节点提供资源实例，并且在另一个可用区域内为另一个数据库引擎头节点指定资源实例容量，而不实例化其他数据库引擎头节点。 虽然服务使用主要资源实例容量预期运行，但应急资源能力可以在现货市场上租赁给其他实体。 对于特定服务（例如，在故障转移期间）需要时，可能会撤销应急实例容量的租约。

    Abstract: A method for backing up a database includes identifying n portions of a database wherein each of the n portions is greater than 0% and less than 100% of the database. The method also includes performing a complete backup of a first 1/n portion of the database and performing an incremental backup on the remaining (n−1)/n portion of the database, and for each subsequent backup, performing a complete backup of a next 1/n portion of the database and performing an incremental backup on the remaining (n−1)/n portion of the database.
