Abstract
A method, article of manufacture, and apparatus for backup operations. A read request is received for a data segment at a deduplicated storage system. The data segment is determined not to be in a data cache on the deduplicated storage system. A data segment reference for the data segment is determined to be in a data segment reference cache on the deduplicated storage system. The data segment is read from a persistent storage using the data segment reference.
