Efficient data synchronization in a distributed data recovery system |
摘要 |
A method for synchronizing data stored on primary and secondary storage volumes in a distributed data recovery system is provided. The method comprises associating N data recovery relationships between a primary volume and N secondary volumes by way of implementing N data structures respectively. Each data structure comprises a first indicator that indicates whether data stored on a first track of the primary volume has been updated, due to a first operation performed by a host application. One or more of the N data structures are stored in at least a first data storage medium with high speed data access rates. |
