摘要： Storing recovery data includes providing chunks of data to a remote destination, where each chunk of data represents data written before a first time and after a second time and where the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks, providing synchronous data to a local destination, and providing an indicator to the local destination in connection with creation of a new chunk of data for storage at the remote destination. The local destination may maintain a plurality of maps, where each of the maps associates synchronous data being provided thereto with a specific chunk of data. In response to receiving an indicator in connection with creation of a new chunk of data, the local destination may point to a new map. There may be two maps or more than two maps.

摘要： Described are techniques used in performing data replication processing. Data is replicated on a recovery site from a production site. When a disaster occurs, the state of the replication processing is determined and a restart copy of the data is made available from the recover site. Processing continues based on whether protection mode is desired such that the system executes using the recovery site as the restart with a replicated copy of the data. Data is propagated from the recovery site to the production site to resume operations and replication processing originating from the production site.

摘要： Storing recovery data includes a host processor writing data to a local storage device, the host processor causing the local storage device to accumulate chunks of data corresponding to writes by the host processor, where each chunk of data represents data written before a first time and after a second time and where the second time for one of the particular chunks of data corresponds to a first time for a subsequent one of the particular chunks of data, transmitting the chunks of data from the local storage device to a remote destination, providing synchronous data from the local storage device to a local destination; and, the host processor causing an indicator to be provided to the local destination in connection with creation of a new chunk of data for storage at the remote destination. The local destination may maintain a plurality of maps, where each of the maps associates synchronous data being provided thereto with a specific chunk of data. In response to receiving an indicator in connection with creation of a new chunk of data, the local destination may point to a new map. There may be two maps or more than two maps.

摘要： Maintaining continuous availability of tape data includes providing a first storage space that contains the tape data, where metadata for the tape data points to the first storage space, creating a data mirroring relationship between the first storage space and a second, separate, storage space, where tape data written to the first storage space is copied to the second storage space, and adjusting the metadata for the tape data to reference the second storage space in response to the first storage space becoming inaccessible. Maintaining continuous availability of tape data may also include suspending access to the tape data prior to adjusting the metadata. Maintaining continuous availability of tape data may also include resuming access to the tape data after adjusting the metadata.

摘要： A system for injecting I/O faults into a closed system, for example, the injection of link level I/O faults, involves the use of a simulated computing environment. In an embodiment, the system provides for fault injection using an emulated IBM System z environment and including the use of FICON and/or other suitable communication channel protocols. The emulated System z environment may include a simulated z/OS and/or emulated System z hardware and software components.
