Abstract
Methods that can provide distributed data deduplication reference counting are disclosed herein. One method includes generating, by a processor, a secondary reference in response to a determination that a data chunk is a copy of the primary reference in which the primary reference includes a pointer to an existing data chunk stored on a storage device. The method further includes incrementing a secondary reference counter on the primary reference in response to generating the secondary reference. Apparatus and computer program products that can include, perform, and/or implement the methods are also disclosed herein.
