    Abstract: A system can maintain multiple queues for deduplication requests of different priorities. The system can also designate priority of storage units. The scheduling priority of a deduplication request is based on the priority of the storage unit indicated in the deduplication request and a trigger for the deduplication request.

    Abstract translation: 系统可以为不同优先级的重复数据删除请求维护多个队列。 系统还可以指定存储单元的优先级。 重复数据消除请求的调度优先级是基于重复数据消除请求中指示的存储单元的优先级和重复数据删除请求的触发。

    Abstract: Techniques for a method of estimating deduplication potential are disclosed herein. The method includes steps of selecting randomly a plurality of data blocks from a data set as a sample of the data set, collecting fingerprints of the plurality of data blocks of the sample, identifying duplicates of fingerprints of the sample from the fingerprints of the plurality of data blocks, estimating a total number of unique fingerprints of the data set depending on a total number of the duplicates of fingerprints of the sample based on a probability of fingerprints from the data set colliding in the sample, and determining a total number of duplicates of fingerprints of the data set depending on the total number of the unique fingerprints of the data set.

    Abstract: Systems for deduplicating one or more storage units of a storage system provide a scheduler, which is operable to select at least one storage unit (e.g. a storage volume) for deduplication and perform a deduplication process, which removes duplicate data blocks from the selected storage volume. The systems are operable to determine the state of one or more storage units and manage deduplication requests in part based state information. The system is further operable to manage user generated requests and manage deduplication requests in part based on user input information. The system may include a rules engine which prioritizes system operations including determining an order in which to perform state-gathering information and determining an order in which to perform deduplication. The system is further operable to determine the order in which storage units are processed.
