Abstract
Enhancing data replication performance optimization by maintaining parent-child file relationships when cloning an entire or portion of a first namespace to a second namespace for backups cloned across namespaces in a deduplication filesystem. The file copies may be made by either virtual synthetic (VS) copies that keep a one-way relationship between parent-child files or fast copy overwrite (FCOW) copies that keep a two-way parent-child relationship. Extended attributes are used as metadata for the files to indicate a path or recipe to generate the child file. The extended attributes for the cloned parent and child files are fixed to reference the second namespace so that a relative relationship between the parent and child files is maintained after cloning to the second namespace.
