摘要：
A system and method for implementing data deduplication-aware copying of data are provided. In response to a request to copy a source file between a source filesystem and a destination filesystem, file mapping information corresponding to the source file is retrieved. The file mapping information is stored in a source filesystem map. The source filesystem accesses a source logical volume. The source logical volume maps to a deduplication storage area. The destination filesystem accesses a destination logical volume. The destination logical volume maps to the deduplication storage area. The source file comprises data stored in the deduplication storage area. A destination file is allocated, based on the file mapping information, in the destination filesystem. The destination file is mapped to the data stored in the data deduplication storage area.
