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： 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。

摘要： Provided are a method, system, and program for managing a relationship between one target volume and one source volume. Information is maintained in memory on an existing relationship between at least one source volume and at least one target volume, comprising: (i) at least one element, wherein each element represents a range of sequential data units in the volume; (ii) at least one relationship entry, wherein each relationship entry represents one relationship; and (iii) at least one element pointer associating one element with one relationship entry, wherein the data units represented by the element are part of the relationship represented by the relationship entry that the pointer associates with the element. A new relationship between at least one target volume and at least one source volume is added. Further, added is a new relationship entry in the memory representing the new relationship and one new element pointer is added in the memory for each element including data units included in the new relationship to associate the element with the new relationship entry, wherein the data units represented by the element are part of the new relationship.

摘要： A novel and useful mechanism and method for writing data updates to a data cache subsystem of a storage controller. Updates received by the storage controller requiring storage allocation on a repository volume are delayed prior to being written to the data cache subsystem. The delay is based on the storage utilization of the repository volume. As the utilization of the repository volume increases, the cache write delay increases, thereby limiting the possibility that there will still be any updates in the data cache subsystem waiting to be destaged to the repository volume when the repository volume is fully utilized. When the repository volume is fully utilized all writes to the data cache of updates that will cause destage of tracks in the repository volume are stopped, thereby causing an infinite delay.
