摘要： A backup server controls the backing up of data stored on a mass storage subsystem in response to a backup request from a host identifying data to be backed up during a backup operation, the mass storage subsystem storing data in a plurality of mirrored copies. The backup server comprises a discovery module, a preparation module, an execution module and a clean-up module. The discovery module receives the backup request and identifies, during a discovery phase, at least one storage location on the mass storage subsystem on which data to be backed up during the backup operation is stored. The preparation module, during a preparation phase following the discovery phase, enables the mass storage subsystem to sever one of said mirrored copies and make it available to backup server for the backup operation. In addition, prior to enabling the mass storage subsystem to sever one of the mirrored copies, the preparation module will notify the host, which will stop operating in connection with the data from the mass storage subsystem, and after the mirrored copy has been severed, the preparation module will so notify the host so that it can resume operating in connection with data from at least one of the other copies. The execution module, during the execution phase, enables the mass storage subsystem to retrieve data from the at least one storage location and transfer the retrieved data to the backup server to facilitate backup storage. The clean-up module, during a clean-up phase following the execution phase, verifies that the data to be backed up has been stored in backup storage and enable the mass storage subsystem to re-synchronize the mirrored copies. The backup server also performs a restore operation in response to a restore request from the host.
摘要翻译：响应来自主机的备份请求，备份服务器控制存储在大容量存储子系统中的数据的备份，该备份请求在备份操作期间识别待备份的数据，大容量存储子系统将数据存储在多个镜像副本中。备份服务器包括发现模块，准备模块，执行模块和清理模块。发现模块接收备份请求，并在发现阶段期间识别大容量存储子系统上的至少一个存储位置，在该存储子系统上存储备份操作期间要备份的数据。准备模块在发现阶段之后的准备阶段，使大容量存储子系统能够切断所述镜像副本之一，并使备用服务器可用于备份操作。此外，在使大容量存储子系统能够切断镜像副本之前，准备模块将通知主机，其将停止与大容量存储子系统的数据相关的操作，并且在镜像拷贝被切断之后，准备模块将这样通知主机，使得它可以恢复与至少一个其他副本的数据相关的操作。执行模块在执行阶段期间使大容量存储子系统能够从至少一个存储位置检索数据，并将所检索的数据传送到备份服务器以便于备份存储。清理模块在执行阶段之后的清理阶段，会验证要备份的数据是否已经存储在备份存储器中，并使大容量存储子系统能够重新同步镜像副本。备份服务器还会执行恢复操作以响应来自主机的恢复请求。

摘要： Described are techniques for controlling a flow of I/O requests. R is received denoting a current maximum number of outstanding I/O requests allowed to be issued by a first data storage system to a second data storage system over a path. Assessment processing is performed to obtain a first performance value, a second performance value, and a third performance value, respectively, when the maximum number of outstanding I/O requests allowed to be issued by the first data storage system to the second data storage system over the path is R+delta1, R, and R−delta2 (delta1 and delta 2 are positive integer values). It is determined whether to update R in accordance with criteria including the first performance value, the second performance value and the third performance value.
