摘要： A data processing system includes a first storage system including a first host and a first storage subsystem. The first host has access to a first copy manager that is operable to manage a data replication operation. A second storage system includes a second host and a second storage subsystem. The second host has access to a second copy manager that is operable to manage a data replication operation. A first communication link is coupled to the first storage system and the second storage system to exchange management information between the first and second storage systems in order to manage the data replication operation. A data transfer path is configured to transfer data stored in the first storage subsystem to the second storage subsystem and replicate the data of the first storage subsystem in the second storage subsystem. The data transfer path is different from the first communication link.

摘要： A storage system maintains a journal of journal entries and at least one snapshot of one or more data volumes. By assigning a unique sequence number to journal and snapshot, it is easy to find a journal which can be applied to the snapshot. A technique is described for detecting an overflow condition of running out of journal space and recovering the journal space.

摘要： Disclosed is a method to synchronize the state of an application and an application's objects with data stored on the storage system. The storage system provides API's to create special data, called a marker journal, and stores it on a journal volume. The marker contains application information, e.g. file name, operation on the file, timestamp, etc. Since the journal volume contains markers as well as any changed data in the chronological order, IO activities to the storage system and application activities can be synchronized.
