摘要： Provided are a system and article of manufacture for copying storage. Copy operations are performed on source storage units to copy to target storage units, wherein the copy operations create a consistent copy of the source storage units in the target storage units. While performing a copy operation to copy from one source storage unit to one target storage unit, a write operation is restricted from being performed on the one source storage unit, until the copy operations have been performed on the source storage units.

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.

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 system for managing variable sized pages of possibly non contiguous blocks in a Non-Volatile-Storage (NVS) for attaining a consistent NVS that survives malfunction events. Each page includes a self describing block or linked list of self describing blocks. the system includes: Volatile Storage storing auxiliary modules, means for performing an atomic “create a new page” procedure. Means for performing an atomic write “add block” procedure for adding a possibly non contiguous block to a page. The newly added block has a back pointer to a previous block in the page. Means for performing a “delete page” procedure for deleting all blocks in a page. Means for performing a recovery procedure for rolling backward the add block procedure and rolling forward the delete page procedure, in case of malfunction event, thereby attaining consistent NVS.

摘要： Systems and methods for optimizing deduplication in a data storage system are provided. The method comprises associating a first name with first data blocks including first content stored in a data storage system, wherein the first name is associated with the first data blocks by way of a reference to a first meta file that points to a data file which points to the first data blocks; storing a first signature derived from the first content in an indexing data structure, wherein the first signature is used to associate the first name with the first data blocks and as means to verify whether a second content is a duplicate of the first content, based on value of a second signature derived from the second content.
