Abstract
Provided are a computer program product, system, and method for identifying modified chunks in a data set for storage. Information is maintained on a data set of variable length chunks, including a digest of each chunk and information to locate the chunk in the data set. Modifications are received to at least one of the chunks in the data set. A determination is made of chunks including data affected by the modifications. The determined chunks including data affected by the modifications are processed to determine new chunks and for each determined new chunk and for each determined new chunk, new digest information of the new chunk. The new digest information on the at least one new chunk and information to locate the new chunk in the data set are added to the set information.
