    • A backup system in accordance with an implementation of the present invention includes one or more light-weight (i.e., stateless) storage nodes that are positioned close enough to one or more assigned production servers to enable as rapid and efficient a data recovery as possible. The one or more light-weight storage nodes are driven by, and implement backup policies in accordance with, control settings determined by and received from a centralized backup server. Changes to the control settings are simply produced at the centralized backup server and propagated to each storage node in the system. In addition to efficient backup times, general backup administration can be greatly simplified at least in part since a large number of production serves can be serviced through a small or large number of light-weight storage nodes, which in turn can be managed by a single centralized backup server.

    • Controlling data retention of a collection of data in a data store. An instruction is received to store a shadow collection of data to the data store. The data store has a previous version of the shadow collection of data. An available amount of data storage space on the data store is identified. An amount of data storage space needed is estimated for storing the shadow collection of data to the data store based on the received instruction. It is determined whether the identified available amount of data storage space is sufficient for storing the estimated amount of data storage space. The shadow collection of data is stored to the data store when said determine indicates that the identified available amount of data storage space is sufficient and the previous version is permitted to be deleted or to be overwritten.

    • Implementations of the present invention provide systems, methods, and components configured to preserve valid shadow copies during replication cycles, before those valid shadow copies have expired. In particular, one or more components can identify the size and rate of changes in production server data that will be applied to a new volume shadow copy. The components can then determine the storage area that would be needed to store the new volume shadow copy in the backup volume and apply changes onto the backup volume if there is appropriate space. If there is not an appropriate amount of space, the components can alert the system that new action should be taken to preserve both prior, valid shadow copies as well as new shadow copies. For example, a backup administrator may need to increase the shadow copy storage space, or assign a new storage medium for handling new shadow copies.
    • 本发明的实现提供了在复制周期之前,在这些有效卷影副本已经过期之前被配置为保留有效卷影副本的系统,方法和组件。 特别地,一个或多个组件可以识别将应用于新的卷影副本的生产服务器数据的更改的大小和速率。 然后,组件可以确定将新卷卷副本存储在备份卷中所需的存储区域,如果存在适当的空间,则将更改应用于备份卷。 如果没有足够的空间,组件可以提醒系统应该采取新的操作来保留先前有效的卷影副本以及新的卷影副本。 例如,备份管理员可能需要增加卷影副本存储空间,或分配新的存储介质来处理新的卷影副本。
