摘要： An advanced clock synchronization technique is adapted for use with a replication service in a data backup and recovery storage environment. The storage environment includes a plurality of source storage systems and target storage systems, wherein the source storage systems are illustratively embodied as source replication nodes. The advanced clock synchronization technique establishes a software-only, loosely-accurate global clock based on a timestamp and an associated error boundary. Notably, the timestamp and its error boundary are used as global clock information to enable synchronization (i.e., ordering of storage requests) among the source replication nodes and/or the target storage systems, thereby ensuring consistent replication of the storage requests on the target storage systems.

摘要： System for the storage and maintenance of data sets updates in a storage subsystem, that comprises direct access storage device(s) that serves as the main storage of the storage subsystem and on which the data sets are originally stored; a Cache memory storage device that enables fast interaction with the storage subsystem, on which a copy of the data sets is stored; a non-volatile storage device partitioned into a plurality of fixed size non-volatile memory pages. The system employs an update process, in which the changes to the data sets are applied to the data set copy stored on the Cache memory device; a journal of the changes that are being made to the data sets stored on the Cache memory device, utilizing the non-volatile memory pages to store update records reflecting the changes in the data sets; a reconstruction process in which the data sets are reconstructed utilizing the update records stored on the non-volatile memory pages, and the data sets stored on the direct access storage device; and a process for freeing arbitrary non-volatile pages from their prior association with data sets that are stored in the Cache memory.

摘要： Disclosed is a method, system, program, and data structures for maintaining electronic data at a point-in-time. A first data structure indicates point-in-time data at one of a first storage location and a corresponding second storage location. A second data structure indicates point-in-time data at one of a first storage location and corresponding second storage location. A first relationship data structure indicates a relationship between the first storage location and corresponding second storage location and a second relationship data structure indicates a relationship between the first storage location and second storage location. A request to process the first storage location is processed by processing the first relationship data structure to determine the corresponding second storage location for the first storage location and processing the first data structure to determine whether data at the first storage location was transferred to the second storage location. A request to process the second storage location is processed by processing the second relationship data structure to determine the corresponding first storage location for the second storage location and processing the second data structure to determine whether the point-in-time data at the first storage location was transferred to the second storage location.

摘要： A method and system are disclosed for transferring backup copies of designated multi-track datasets which are stored in a plurality of storage subsystems to a host system via data channel during concurrent execution of an application. Upon receiving a request for a backup copy, execution of an application is temporarily suspended. A dataset logical-to-physical storage system address concordance is formed and execution of the application is resumed thereafter. Any application initiated updates to affected tracks within the designated datasets which occur prior to generation of a backup copy are processed by buffering the updates, copying the affected tracks to storage subsystem memory, updating the address concordance and writing the updates to the affected tracks within the dataset. Requests from the host system to transfer a selected sequence of tracks within the designated multi-track dataset are then examined to determine if the sequence includes affected tracks which have previously been copied to storage subsystem memory. An artificial track is then automatically substituted into the requested sequence of selected tracks for each affected track which has previously been copied to storage subsystem memory during transfer of the selected sequence of tracks such that the host system is made aware of the previous copying of these affected tracks.

摘要： A delta query technique transmits only latest changes to data of objects from a server to one or more clients in response to a client query (request) to access the object data. A global counter is maintained for all of the objects served by the server. Every time the data of an object changes, a value of the global counter increments (updates) and the updated global counter value is then assumed (“inherited”) by that object. In addition, the global counter is updated when a client issues a request to access one or more objects. If the data of the objects has changed since the last time the client accessed the objects, the server responds with the latest object data and the updated global counter value. Notably, each client maintains a local counter having a value that, upon receipt of the latest object data, is modified to reflect the updated global counter value.

摘要： A write ordering style asynchronous replication service utilizes a loosely-accurate global clock in a data backup and recovery storage environment. The storage environment includes a set of source storage systems illustratively embodied as source replication nodes that cooperate to maintain a consistency group that may span multiple geographical sites. The storage environment also includes one or more target storage systems illustratively embodied as target replication nodes configured to service the consistency group. The write ordering style service utilizes the loosely-accurate global clock to provide consistent replication of a storage space of the consistency group.

摘要： A target data storage system comprises a peer-to-peer communication link interface for linking the target to a source data storage system, and data storage for storing point in time copy data received from the source via the peer-to-peer communication link interface. Information is established at the target relating logical identification of the point in time copy data to point in time copy data stored at the target and to point in time copy data stored at the source, such that the information references the data storage system having requested point in time copy data. A controller of the target accesses requested point in time copy data at the target if the table indicates that the requested point in time copy data is available at the target; else obtains the requested point in time copy data from the source via the peer-to-peer communication link interface.
