Abstract
Enhancing data replication performance by preserving fastcopy-overwrite optimization for backups cloned across namespace subdivisions in a deduplication filesystem. A process keeps a key value pair for each of the files that are being cloned from the original namespace to a subcopy namespace. The key is the file handle of the file being cloned in the original namespace and the value is the handle of the cloned file in the subcopy namespace. When a subsequent generation backup of the same asset is cloned the basefile target file relationship is transferred as is to the new file in the subcopy namespace. This maintains the basefile to target file relationship after cloning to realize fastcopy-overwrite optimization benefits for the backup to the subcopy namespace.
