Abstract
Machine implemented method and system for generating a disaster recovery copy of an expandable storage volume having a namespace for storing information for accessing data objects stored at a data constituent volume is provided. A transfer operation for transferring a point in time copy of the expandable storage volume from a first location to a second location is generated. Information regarding the expandable storage volume from the first location is retrieved and a destination expandable storage volume is resized to match components of the expandable storage volume at the first location. Thereafter, the point in time copy of the expandable storage volume from the first location to the second location is transferred and configuration information regarding the point in time copy is copied from the first location to the second location; a data structure for storing information regarding the transferred point in time copy of the expandable storage volume is updated.
