    • Systems and methods are disclosed for a system for managing data in accordance with service level agreements (SLAs) that specify schedules on a calendar basis for performing prescribed data management functions and for reducing inter-function redundancy. This system may include a data management engine for performing data management functions, including at least a snapshot function, and at least one back-up function. The data management engine may include a service level policy engine that receives SLAs in electronic form and which controls the scheduling of the data management functions. Each electronic SLA may be associated with a corresponding application and may specify at least one service level policy, each policy specifying a source pool, a destination pool, a copy frequency, a retention period and schedule information. A collection of policies is capable of expressing a non-uniform schedule for when a given function should be performed.
    • 公开了用于根据服务级别协议(SLA)来管理数据的系统和方法,所述服务级别协议(SLA)指定日历上的日程表以执行规定的数据管理功能并且用于减少功能间冗余。 该系统可以包括用于执行数据管理功能的数据管理引擎,至少包括快照功能和至少一个备份功能。 数据管理引擎可以包括以电子形式接收SLA并且控制数据管理功能的调度的服务级策略引擎。 每个电子SLA可以与相应的应用相关联,并且可以指定至少一个服务级别策略,每个策略指定源池,目的地池,复制频率,保留期和调度信息。 一组策略能够表达一个不均匀的时间表,以便何时执行给定的功能。

    • Systems and methods are disclosed for performing a plurality of prescribed data management functions in a manner that reduces redundant access operations to primary storage, where the system includes a data management engine for performing data management functions, including at least a snapshot function and a back-up function. An electronic service level agreement (SLA) specifies a schedule for performing data management functions, where point-in-time images of data include a reference to a baseline image and difference data indicating changes at a later, specific point in time. The data management system also creates a point-in-time image of the primary storage data in response to a schedule requiring some data management functions to be performed concurrently, and communicates the difference information to secondary storage to update the back-up copy of the primary data, such that the primary storage is accessed only once for all updates to the secondary storage.
    • 公开了用于以减少对主存储器的冗余访问操作的方式执行多个规定的数据管理功能的系统和方法,其中系统包括用于执行数据管理功能的数据管理引擎,该数据管理引擎至少包括快照功能和后台管理功能, up功能。 电子服务水平协议(SLA)规定了执行数据管理功能的时间表,其中数据的时间点图像包括对基线图像的引用,以及指示稍后特定时间点的变化的差异数据。 数据管理系统还响应于需要同时执行一些数据管理功能的调度,创建主存储数据的时间点图像,并将差异信息传送到辅助存储器以更新备份副本 主数据,使得主存储仅对辅助存储的所有更新访问一次。
