    • Formulating an integrated disaster recovery (DR) plan based upon a plurality of DR requirements for an application by receiving a first set of inputs identifying one or more entity types for which the plan is to be formulated, such as an enterprise, one or more sites of the enterprise, the application, or a particular data type for the application. At least one data container representing a subset of data for an application is identified. A second set of inputs is received identifying at least one disaster type for which the plan is to be formulated. A third set of inputs is received identifying a DR requirement for the application as a category of DR Quality of Service (QoS) class to be applied to the disaster type. A composition model is generated specifying one or more respective DR QoS parameters as a function of a corresponding set of one or more QoS parameters representative of a replication technology solution. The replication technology solution encompasses a plurality of storage stack levels. A solution template library is generated for mapping the application to each of a plurality of candidate replication technology solutions. The template library is used to select a DR plan in the form of a replication technology solution for the application.

    • The embodiments of the invention provide a method of identifying a recovery point in a continuous data protection (CDP) log. More specifically, the method begins by detecting corrupted data in the CDP log and identifying the nature of corruption. Next, the nature of corruption is mapped to applications to identify components that may have caused the corrupted data. The method then finds a time instance of uncorrupted data in the components. Specifically, this can include searching CDP log entries in an order independent of log event age. Alternatively, the process of finding the time instance can include creating a data image of a first copy of uncorrupted data and sequentially apply entries of the CDP log until the corrupted data is reached.
    • 本发明的实施例提供了一种识别连续数据保护(CDP)日志中的恢复点的方法。 更具体地说,该方法开始于检测CDP日志中的损坏的数据并识别腐败的性质。 接下来,将腐败的性质映射到应用程序,以识别可能导致损坏的数据的组件。 该方法然后在组件中找到未被破坏的数据的时间实例。 具体来说,这可以包括以独立于日志事件年龄的顺序搜索CDP日志条目。 或者,查找时间实例的过程可以包括创建未损坏数据的第一副本的数据映像,并且顺序地应用CDP日志的条目,直到到达损坏的数据。
