Title:
COORDINATED STORAGE MANAGEMENT OPERATIONS IN REPLICATION ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO2005066783
Kind Code:
A3
Abstract:
A method, system, computer systern, and computer-readable medium for maintaining up-to-date, consistent copies of primary data without the need to replicate modified data when the data were modified as a result of an operation that is not an application-driven write operation captured during replication. Selected storage management operations are performed on the primary and secondary data stores at points in time when the data are the same to ensure that the data stored within the data stores remain consistent. These selected storage management operations include operations that produce modified data stored in the primary data store, where a portion of the modified data are not replicated to a secondary node. Other types of storage management operations are selected to be performed on both the primary and secondary data stores, where the operations do not directly change data in the primary data store, but may affect data stored in the primary data store.
