Described herein is a system and method for retaining deduplication of data blocks of a resulting storage object (e.g., a flexible volume) from a split operation of a clone of a base storage object. The clone may comprise data blocks that are shared with at least one data block of the base storage object and at least one data block that is not shared with at least one data block of the base storage object. The data blocks of the clone that are shared with the base storage object may be indicated to receive a write allocation that may comprise assigning a new pointer to an indicated data block. Each data block may comprise a plurality of pointers comprising a virtual address pointer and a physical address pointer. As such, data blocks of the clone comprising the same virtual address pointer may be assigned a single physical address pointer. Thus, a new physical address pointer is assigned or allocated once to a given virtual address pointer of data blocks of a clone.
A system, comprising at least one processor and memory, for managing data on a storage system, the storage system providing data storage for a storage object and a clone of the storage object, the system configured for:
A method for managing data on a storage system, the storage system providing data storage for a storage object and a clone of the storage object, the method comprising:
A non-transitory computer readable medium carrying one or more instructions for managing data on a storage system, the storage system providing data storage for a storage object and a clone of the storage object, wherein the one or more instructions, when executed by one or more processors, cause the one or more processors to perform:
