A scalable approach is disclosed for processing auxiliary-copy jobs in a storage management system by using distributed media agent resources instead of a centralized storage manager. Enhanced media agents coordinate and control auxiliary-copy jobs and tap the storage manager to reserve data streams and provide job-specific metadata on demand. An enhanced storage manager may initially select a media agent as 'coordinator' to coordinate auxiliary-copy jobs with any number of other media agents, which act as 'controllers.' A coordinator media agent is generally responsible for obtaining data stream reservation information from the storage manager and assigning auxiliary-copy jobs to respective controller media agents, based on the components involved in the respective reserved data streams.

According to certain aspects, a method can include receiving an indication that a restoration of a deduplication database using a secondary copy of a file associated with a secondary copy job is complete; retrieving a first data fingerprint from a data storage database, wherein the first data fingerprint is associated with the secondary copy job used to restore the deduplication database; retrieving a second data fingerprint from a deduplication database media agent, wherein the second data fingerprint is associated with the secondary copy job used to restore the deduplication database; comparing the first data fingerprint with the second data fingerprint to determine whether the first data fingerprint and the second data fingerprint match; and transmitting an instruction to the deduplication database media agent to rebuild the restored deduplication database in response to a determination that the first data fingerprint and the second data fingerprint do not match.
