Abstract
A method, article of manufacture, and apparatus for performing backup operations using a deduplicated storage system is presented. A data segment can be received at a deduplicated storage system. A fingerprint can be calculated for the data segment. The fingerprint and the offset can be stored in a reference cache on the deduplicated storage system. A metadata segment can be loaded from the deduplicated storage system. The metadata segment can be updated to include the fingerprint. Backup operations may include storage and management using a tree structure.
