    摘要: Handling failure of a primary group at a first data center that is part of plurality of data centers providing triangular asynchronous replication includes creating a data mirroring relationship between at least one storage volume at a second data center having a synchronous backup group that is part of the plurality of data centers and at least one storage volume at a third data center having an asynchronous backup group that is part of the plurality of data centers and resuming work at the third data center. Handling failure of a primary group at a first data center may also include synchronizing the at least one storage volume at the second data center with the at least one storage volume at the third data center prior to resuming work at the third data center.

    摘要: A primary group may be swapped with a synchronous backup group where triangular asynchronous replication is being provided between the primary group, the synchronous backup group and an asynchronous backup group. Swapping may include halting work at the primary group, transferring pending mirrored data from the primary group to an asynchronous backup group, creating a data mirroring relationship between a storage volume at the synchronous backup group and a storage volume at the asynchronous backup group, reversing a data mirroring relationship between the storage volume at the primary group and the storage volume at the synchronous backup group, and resuming work at the asynchronous backup group.

    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.
