摘要： Methods, computer systems, and computer program products for processing data a computing environment are provided. The computer environment for data deduplication storage receives a plurality of write operations for deduplication storage of the data. The data is buffered in a plurality of buffers with overflow temporarily stored to a memory hierarchy when the data received for deduplication storage is sequential or non sequential. The data is accumulated and updated in the plurality of buffers per a data structure, the data structure serving as a fragment map between the plurality of buffers and a plurality of user file locations. The data is restructured in the plurality of buffers to form a complete sequence of a required sequence size. The data is provided as at least one stream to a stream-based deduplication algorithm for processing and storage.

摘要： Various embodiments for replicating deduplicated data using a processor device are provided. A block of the deduplicated data, created in a source repository, is assigned a global block identification (id) unique in a grid set inclusive of the source repository. The global block id is generated using at least one unique identification value of the block, a containing grid of the grid set, and the source repository. The global block id is transmitted from the source repository to a target repository. If the target repository determines the global block id is associated with an existing block of the deduplicated data located within the target repository, the block is not received by the target repository during a subsequent replication process.
摘要翻译：提供了使用处理器设备复制重复数据删除的数据的各种实施例。在源存储库中创建的重复数据删除数据块被分配在包含源存储库的网格集中唯一的全局块标识（id）。使用块的至少一个唯一标识值，包含网格集合的网格和源存储库来生成全局块ID。全局块id从源存储库传输到目标存储库。如果目标存储库确定全局块id与位于目标存储库内的已重复数据消除的数据的现有块相关联，则在后续复制过程中该目标存储库不会接收该块。

摘要： Exemplary system, and computer program product embodiments for optimizing disaster recovery systems during takeover operations are provided. In one embodiment, by way of example only, a flag is set in a replication grid manager to identify replication grid members to consult in a reconciliation process for resolving intersecting and non-intersecting data amongst the disaster recovery systems for a takeover operation. The replication grid members are consulted for the takeover operation to accommodate a coordination of an ownership synchronization process for cartridges not distributed on-time to the replication grid members. Additional system and computer program product embodiments are disclosed and provide related advantages.

摘要： Communication is arrested between a source data entity and a replicated data entity at a location declared in a DR mode. The DR mode is negotiated to a central replication management component as a DR mode entry event. The DR mode entry event is distributed, by the central replication management component, to each member in a shared group. The DR mode is enforced using at least one replication policy.

摘要： A calculated factoring ratio is determined as a weighted ratio of current nominal data to physical data based on at least one storage capacity threshold and a used storage space currently physically consumed by one of backup and replication data. A maximal nominal estimated space in the computing storage environment is calculated. A remaining space, defined as the maximal nominal estimated space minus a current nominal space in the computing storage environment, is calculated. If the remaining space is one of equal and less than a user-configured reservation space for backup operations, data replication operations are accepted and stored in the computing storage environment.

摘要： Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance. The synchronization message is stored locally in a persistent storage location associated with the source component along with an indicator representative of a time the storage operation was performed. Pursuant to receipt of the synchronization message by the replicated component, the replicated component is updated to a dirty state to indicate a lack of full synchronization between the source and replicated instances. Receipt of the synchronization message is acknowledged by the replicated component by sending a dirty state acknowledgement. If, during a subsequent recovery process, the dirty state is not yet cleared, the replicated component is deemed ineligible for participation in a full restoration operation.
摘要翻译：在由源组件对源实例执行的存储操作之后，向复制实例的复制组件发送同步消息。同步消息被本地存储在与源组件相关联的持久存储位置中，以及表示执行存储操作的时间的指示符。根据复制组件接收到同步消息，将复制的组件更新为脏状态，以指示源和复制实例之间缺少完全同步。复制组件通过发送脏状态确认来确认同步消息的接收。如果在后续的恢复过程中，脏状态尚未被清除，则认为复制的组件不符合参与完全恢复操作的资格。

摘要： For coordinated disaster recovery, a reconciliation process is performed for resolving intersecting and non-intersecting data amongst disaster recovery systems for takeover operations. An ownership synchronization process is coordinated for replica cartridges via the reconciliation process at the disaster recovery systems. The disaster recovery systems continue as a replication target for source systems and as a backup target for local backup applications.

摘要： Various embodiments for deduplicated data processing congestion control in a computing environment are provided. In one such embodiment, a single congestion metric is determined from a sampling of a plurality of combined deduplicated data processing congestion statistics in a number of active deduplicated data processes. The congestion limit is calculated from a comparison of the single congestion metric to a congestion target setpoint, the congestion target setpoint being a virtual dimension setpoint and the congestion limit being a manipulated variable. The number of active deduplicated data processes is compared to the congestion limit. If the number of active deduplicated data processes is less than the congestion limit, a new deduplicated data process is spawned.
