摘要： Provided are a method, system, and program for establishing a point-in-time copy. A source relationship data structure and target relationship data structure are generated when establishing a point-in-time copy relationship between source and target storage areas, wherein the source and target relationship data structures each include an indicator for each source storage area and corresponding target storage area in the point-in-time copy relationship. The source and target relationship data structures are initialized to set the indicator for each source storage area and corresponding target storage area in the point-in-time copy relationship to a first value. A determination is made that data was written to one target storage area after establishing the point-in-time copy relationship. The indicators in the source and target relationship data structures corresponding to the source storage area and corresponding target storage area to which data was written are set to a second value.

摘要： Provided are a method, system, and program for forming a consistency group of data. A command is received to form a consistency group with respect to data received at a first storage site that is mirrored to a second storage site. A first data structure is provided indicating updates to the first storage site not included in the consistency group that are received after the command and a second data structure is provided indicating updates to the first storage site in the consistency group to be formed. A command is transmitted to cause data copied to the second storage site that is part of the consistency group to be copied to a third storage site. Indication is received when the data in the second storage site that is part of the consistency group is copied to the third storage site.

摘要： Provided are a method, system, and program for forming a consistency group of data. Information is provided on a consistency group relationship indicating a plurality of slave controllers and, for each indicated slave controller, a slave storage unit managed by the slave controller. A command is transmitted to each slave controller in the consistency group relationship to cause each slave controller to transmit data in the slave storage unit to a remote storage in a manner that forms the consistency group. A determination is made as to whether all the slave controllers successfully transmitted the data in the slave storage units that is part of the consistency group to the remote storage.

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.

摘要： Disclosed is a technique for applying changes back to an original copy of data to reduce an amount of data transferred. A first indicator is maintained for each block of data in a first storage to indicate whether the block of data has been updated in the first storage since the block of data was last transferred to a second storage. A second indicator is maintained for each block of data in the second storage to indicate whether the block of data has been updated in the second storage since the block of data in the second storage was overwritten by a corresponding block of data in the first storage. Upon receiving a reverse restore operation, each block of data in the second storage for which a second indicator has been set to indicate that the block of data has been updated is transferred to the first storage and each block of data in the second storage that corresponds to a block of data in the first storage for which a first indicator has been set to indicate that the block of data in the first storage has been updated is transferred to the first storage.
摘要翻译：公开了一种用于将更改应用于数据的原始副本以减少传送的数据量的技术。对于第一存储器中的每个数据块来维持第一指示符，以指示数据块是否已经在第一存储器中被更新，因为数据块最后传送到第二存储器。维持第二存储器中的每个数据块的第二指示符，以指示在第二存储器中数据块是否已被更新，因为第二存储器中的数据块被第一存储器中相应的数据块覆盖。在接收到反向恢复操作时，第二存储器中的已经被设置为指示数据块已被更新的第二存储器中的每个数据块被传送到对应于第二存储器的第一存储器和第二存储器中的每个数据块涉及第一存储器中已经设置了第一指示符以指示第一存储器中的数据块已经被更新的数据块被传送到第一存储器。

摘要： Disclosed is a technique for reducing an amount of data transferred. A first indicator is maintained for each source block of data to indicate whether the source block of data has been updated in source storage since the source block of data was last transferred to target storage. A second indicator is maintained for each target block of data in target storage to indicate whether the target block of data has been updated in target storage since the target block of data was overwritten by a corresponding source block of data. When transferring data from the source storage to the target storage, each source block of data for which a first indicator has been set to indicate that the source block of data has been updated is transferred and each source block of data that corresponds to a target block of data for which a second indicator has been set to indicate that the target block of data has been updated is transferred.
摘要翻译：公开了一种减少传送数据量的技术。为每个数据源块维护第一个指示符，以指示源数据源是否已经在源存储器中更新，因为源数据块最后传输到目标存储。为目标存储器中的每个目标数据块保持第二指示符，以指示目标数据块是否已经在目标存储器中被更新，因为目标数据块被相应的源数据块覆盖。当将数据从源存储器传送到目标存储器时，传送已经设置了第一指示符的数据的源数据块，以指示源数据块已经被更新，并且每个与目标块对应的源数据块的第二指示符被设置为指示目标数据块已被更新的数据被传送。
