摘要： Disclosed are a system, a method, and a computer program product to provide for the optimization of the output transfer load balance between the peer computers transferring data to one or more storage devices. The peer computers receive, organize and transfer the data to storage devices. The data set is composed of a plurality of data transfers. After an initial division of the data transfers between the two peers, each peer will have assigned responsibility for a number of data transfers. If the one of the peer computers completes offloading transactions earlier than the other peer, then the peer that is still transferring data will employ the other peer to execute a portion of the remaining data transfers. The operation of the system is symmetrical in that either peer may assist the other peer depending upon which peer has idle time. In addition the operation is autonomous and self-adjusting resulting in the peer nodes optimizing the size of the portion of data transfers that are reassigned during the operation of the invention resulting in the minimization of idle time for either peer. The self-adjusting feature allows the system to react to changing conditions that affect data transfer rates to the storage devices.

摘要： A network component useful in tracking write activity by writing logs containing write address information is described. The tracking component may be used in networked systems employing data mirrors to record data block addresses written to a primary storage volume during the time a data mirror is unavailable. The tracking component can be available to any network originating node, and may therefore track write activity on multiple volumes. At the time a data mirror is reconstructed, the log written may be used to construct a list of block addresses pointing to locations on a primary storage volume wherein data differs from a secondary storage volume member of the mirror. The locations may be copied from the primary to secondary storage volume to reconstruct the data mirror. The performance impact of the tracking component is minimal and a shared network resource is offered that increases fault tolerance in the event of backup device failures.
摘要翻译：描述了通过写入包含写入地址信息的日志来跟踪写入活动的网络组件。跟踪组件可以用于使用数据镜来记录数据镜不可用时写入主存储卷的数据块地址的网络系统。跟踪组件可用于任何网络始发节点，并且因此可以跟踪多个卷上的写入活动。在重建数据镜像时，所写入的日志可以用于构造指向主存储卷上的位置的块地址的列表，其中数据与镜像的辅助存储卷成员不同。这些位置可以从主存储卷复制到次存储卷，以重构数据镜像。跟踪组件的性能影响最小，并提供共享网络资源，从而在备份设备故障的情况下增加容错能力。

摘要： Disclosed is a system, method, and article of manufacture for maintaining consistent copies of data between a primary site and a secondary site.One or more backup components receive backup messages from the primary site describing transactions. Transactions received from the primary site at the backup components are referred to as “inbound transactions.” The backup components associate these inbound transactions with an identifier such that all transactions associated with a certain identifier comprise all of the activity on the consistency group for a certain period of time. The backup captain periodically notifies the backup components to pause (i.e., stop receiving inbound transactions temporarily), and once all backup components indicate that they have paused, the backup components are notified to resume receiving transactions and associate the newly received transactions with a new identifier.At the same time, the backup components are sending transactions to the secondary storage devices. Transactions sent from caches at the backup components to the secondary site are referred to as “outbound transactions.” The backup components send all transactions from the current outbound consistent transactions set, temporarily stop sending outbound transactions, and notify the backup captain that they have completed sending the current outbound consistent transactions set. When all backup components have completed sending the current outbound consistent transactions set, the backup captain causes consistent copies to be made at secondary storage and notifies the backup components to send the next outbound consistent transactions set.

摘要： Disclosed are a system, a method, and a computer program product to efficiently create consistent transaction sets to maintain one or more copies of data at different data storage sites. All transactions sent to a primary backup appliance during a consistent transaction set creation interval are formed into a consistent transaction set by efficiently adding new transactions as they are received and removing unnecessary transfers as newer versions arrive. When the creation interval has expired, the complete consistent transaction set is transferred to a secondary backup appliance to be used to update a consistent backup copy of the primary site data. For each consistent transaction set, there will be a tree data structure (a search tree) created that contains the addressing information for all of the blocks of data in the consistent transaction set. The tree data structure used is a modified splay tree, which is a specialization of a binary search tree such that accessed nodes are “percolated” to the top of the tree for faster subsequent access. Secondary data consistency is maintained because the consistent transaction sets are applied whole at the secondary site, and after application, the secondary volumes are exact copies of the primary volumes at the time the consistent transaction set was completed.
摘要翻译：公开了一种系统，方法和计算机程序产品，用于有效地创建一致的事务集以在不同的数据存储站点维护一个或多个数据副本。在一致的事务集创建间隔期间发送到主备份设备的所有事务通过在接收到高效添加新事务时被形成为一致的事务集，并在新的版本到达时删除不必要的传输。创建间隔已过期时，完整的一致事务集将传输到辅助备份设备，以用于更新主站点数据的一致备份副本。对于每个一致的事务集，将创建一个包含一致事务集中所有数据块的寻址信息的树数据结构（搜索树）。所使用的树数据结构是一个修改后的播放树，它是一个二叉搜索树的专门化，使得被访问的节点被“穿越”到树的顶部，以便更快的后续访问。维持辅助数据一致性，因为一致的事务集整体应用于辅助站点，并且在应用程序之后，辅助卷是一致事务集完成时主卷的精确副本。

摘要： Disclosed is a technique for transferring data using multiple backup components. Responsibility for a portion of data is assigned to a first backup component. When a data update for the portion of data is received at the first backup component from a primary source, the data update is mirrored to a second backup component that is not assigned responsibility for the portion of data.Also disclosed is a technique for processing data updates with a group of backup components. It is determined that a new backup component is active. Near an end of a consistent transactions set formation period, responsibility for one or more portions of data are assigned to each backup component in the group and to the new backup component. During a next consistent transactions set formation period, data updates are processed with each backup component in the group and the new backup component.Moreover, disclosed is a technique for processing data updates with a group of backup components. It is determined that a first backup component in the group is no longer available. Portions of data for which the first backup component had been assigned responsibility are reassigned to each of the other backup components in the group.
