Abstract
A method for re-establishing a backup relationship between first and second volumes associated with one or more storage media in a data storage system is provided. The method comprises storing first information for preserving the backup relationship, in response to or in advance of receiving a request to terminate the backup relationship; recording changes to the first or second volumes that occur subsequent to terminating the backup relationship; and re-establishing the backup relationship between the first and second volumes according to the first information such that the first and second volumes are synchronized by merging the recorded changes with the first or second volumes.
