Abstract: Provided are a method, system, and program for managing a relationship between one target volume and one source volume. For each of the source volume and target volume, the memory includes: (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; (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; and (iv) one relationship pointer for each relationship entry associating the relationship entry with volume metadata, wherein the volume metadata provides information on the relationship represented by the relationship entry.

Abstract: PROBLEM TO BE SOLVED: To provide a method, a system and a program for managing the relationship between one target volume and one source volume.
SOLUTION: By at least one element representing a range of a sequential data unit in a volume, at least one relation item representing one relation, and at least one element pointer associating one element with one relation item, information related to an existing relationship between at least one source volume and one target volume is maintained in a memory. Further, when a new relationship between at least one target volume and at least one source volume is added, a new relation item representing the new relationship is added in the memory. Also, one new element pointer for each element is added so as to associate the new relation item with each element including a data unit included in the new relationship.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for executing copying operation. SOLUTION: A fast reverse restore command showing a new source and a new target is received, the new source is an original target, and the new target is an original source. A synchronous scan is executed on the new target. A new target structure associated with the new target is updated, by using a new source structure associated with the new source. This technique for executing copying operation is provided, wherein an instantaneous virtual copy from the new target to the new source is executed, thereafter, a fast reverse restore command is received, and the fast reverse restore command is executed, before a background copy is executed, by the instantaneous virtual copy.

Abstract: 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.

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.
