Abstract
An apparatus for improved version updates in data deduplication includes a baseline module that stores a baseline referrer link in a first cohort of baseline referrer links pointing to a first location in storage where a baseline version data block is stored. The apparatus includes a signpost module that stores to metadata a signpost that points to an updated referrer link in a second cohort of updated referrer links that points to a second location in the deduplicating storage device where an updated version data block is stored in response to the updated version data block being generated. The apparatus includes a cohort update module that replaces the baseline referrer link with the updated referrer link in response to determining that an additional updated version data block matches the updated version data block pointed to by the signpost. A method and a system implement functions of the apparatus.
