Abstract
Official abstract text for this publication.
The subject disclosure is directed towards transforming a file having at least one undeduplicated portion into a fully deduplicated file. For each of the at least one undeduplicated portion, a deduplication mechanism defines at least one chunk between file offsets associated with the at least one undeduplicated portion. Chunk boundaries associated with the at least one chunk are stored within deduplication metadata. The deduplication mechanism aligns the at least one chunk with chunk boundaries of at least one deduplicated portion of the file. Then, the at least one chunk is committed to a chunk store.
First claim
Opening claim text (preview).
What is claimed is: 1. In a computing environment, a method performed at least in part on at least one processor, comprising, re-optimizing a partially deduplicated file having at least one undeduplicated portion-into a fully deduplicated file, in which the partially deduplicated file further has at least one deduplicated portion that is maintained in a chunk store and is referenced by metadata associated with the partially deduplicated file, the re-optimizing including processing…
