Abstract
A method and software is described for recreating on a target datastore a set of hierarchical files that are present on a source datastore. A content identifier (ID) is maintained for each component of the set of hierarchical files. The content ID of a component is updated when its contents are modified. The child component is copied from the source datastore to the target datastore. The content ID corresponding to the parent component on the source datastore is compared with content IDs corresponding to files present on the target datastore. When a matching content ID is discovered, it infers a copy of the parent component. The matching file on the target datastore is associated with the copied child component so that the matching file becomes a new parent component to the copied child component, thereby recreating the set of hierarchical files on the target.
