Zusammenfassung:A writeable clone of a read-only dataset, e.g., an RPPI of a file system, a mirror file system, etc., is created to make the read-only dataset appear from a client's perspective to be modifiable/writeable, yet without actually modifying the read-only dataset itself. Any change attempted to be made on the read-only dataset is stored in the writeable clone. In one embodiment, the clone shares data blocks with the read-only dataset.
