1. A networked information management system configured to verify deduplication information, the networked information management system comprising: a storage manager comprising computer hardware configured to: retrieve, from an electronically stored deduplication database, a chunk integrity table, wherein the chunk integrity table identifies a first data chunk, wherein the first data chunk is associated with a plurality of single instance file (SFile) containers, and wherein the chunk integrity table stores, for each SFile container in the plurality of SFile containers, an indication of whether the respective SFile container is verified; retrieve, from a secondary storage subsystem, the first data chunk, wherein the first data chunk comprises one or more data blocks; for each data block in the first data chunk, determine whether the respective data block comprises a link to one SFile container in the plurality of SFile containers; perform a verification of the respective data block in response to a determination that the respective data block does not comprise the link; and determine a verification status of the respective data block based on the indications of whether the SFile containers are verified stored in the chunk integrity table in response to a determination that the respective data block comprises the link.
