US Patent 10564850 Managing known data patterns for deduplication

Dynamic block optimization for space and performance is disclosed, including: determining that a data pattern associated with a data block included in a write request matches a promoted data pattern; and performing the write request by associating the data block with a previously stored copy of the data block without updating an associated reference count. Dynamic block optimization for space and performance further includes determining that a data pattern associated with a data block included in a write request matches a predetermined data pattern; and performing the write request by storing a static representation associated with the data block and not storing the data block, wherein the static representation is usable to generate the data block.
