摘要： A method, device, and system for resetting snapshots are provided. The reset of a snapshot incorporates the traditional snapshot delete and snapshot create operations into a single operation. Additionally, a snapshot created under the reset operation may receive an array partition from a snapshot being deleted under the same snapshot reset operation thereby retaining its identifying characteristics.

摘要： A data storage system, device, and method are provided for replicating data between different data storage systems or appliances. More specifically, the present invention allows an initiating data storage device to pull data from a target data storage device. Thus, the storage device that is supplying the data can act as a target and does not require the additional software inherent in being an initiator.

摘要： A method and device for managing snapshot data is provided. Snapshots may be created having a preserved data area and a write data area. The preserved data area is used to maintain snapshot data corresponding to the point-in-time when the snapshot was created while the write data area is used to facilitate host read/write access to the snapshot. By maintaining two separate areas, the snapshot can be written to without altering the point-in-time representation of the snapshot.

摘要： Methods and apparatuses for providing a data storage system having snapshot restore capabilities are provided. In particular, snapshots may be taken to represent a state of a storage volume at different times. The state of the storage volume may be returned to the state represented by any snapshot even while the storage volume continues to accept read and write operations. Furthermore, these features are provided in the context of a sparse snapshot structure, according to which multiple copies of individual data chunks are not maintained by the data storage system.
摘要翻译： 提供了用于提供具有快照恢复能力的数据存储系统的方法和装置。 特别地，可以采用快照来表示不同时间的存储卷的状态。 即使存储卷继续接受读写操作，存储卷的状态也可能返回到由任何快照表示的状态。 此外，这些特征是在稀疏快照结构的上下文中提供的，据此数据存储系统不维护各个数据块的多个副本。

摘要： A method and device for performing a volume copy is provided. The volume copy method allows access to both the Volume Copy Source and Volume Copy Target while the volume copy process is occurring. This allows a system administrator to initiate a volume copy without worrying that host access to the Volume Copy Source and Volume Copy Target will be interrupted.
摘要翻译： 提供了用于执行卷拷贝的方法和设备。 卷复制方法允许在卷复制过程发生时访问卷复制源和卷复制目标。 这允许系统管理员启动卷拷贝，而不必担心主机对Volume Copy Source和Volume Copy Target的访问将被中断。

摘要： A data storage system, device, and method are provided for replicating data between different data storage systems or appliances. More specifically, the present invention affords communications between heterogeneous data storage systems that potential employ different communication protocols. A bridging communication protocol is utilized by one or both storage systems in order to accommodate different communication protocols. Alternatively, a storage appliance connecting the data storage systems may employ the bridging communication protocol.

摘要： A method, device, and system are provided for re-initializing a backing store in a data storage system. More specifically, when all snapshots associated with a specified backing store are either being deleted or are marked for deletion the backing store is re-initialized rather than deleting each snapshot independently. The re-initialization of the backing store provides for a quicker way to delete all snapshots than could previously be achieved when each snapshot was deleted independently.
摘要翻译： 提供了一种方法，设备和系统，用于在数据存储系统中重新初始化后备存储。 更具体地说，当与指定后备存储相关联的所有快照都被删除或被标记为删除时，后备存储被重新初始化，而不是独立地删除每个快照。 后备存储的重新初始化提供了一种更快的方式来删除所有快照，而不是单独删除每个快照时先前可以实现的快照。
