Efficient deduplication database validation

A computer-implemented method for validating a deduplication database, the computer-implemented method comprising:

• retrieving, in response to a restoration of the deduplication database using a secondary copy of the deduplication database, a first data fingerprint from a data storage database, wherein the first data fingerprint corresponds with a secondary copy job, wherein the first data fingerprint comprises an indication of a count of unique data blocks stored in a first secondary copy of a first file and an indication of a count of references stored in the first secondary copy of the first file that reference data blocks stored in other secondary copies, wherein execution of the secondary copy job resulted in generation of the first secondary copy of the first file;
• generating a second data fingerprint using the restored version of the deduplication database, wherein the second data fingerprint corresponds with the secondary copy of 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
• rebuilding the restored version of the deduplication database using the first secondary copy of the first file in response to a determination that the first data fingerprint and the second data fingerprint do not match.

A networked information management system configured to validate a deduplication database, the networked information management system comprising:

• a storage manager comprising a storage manager database, wherein the storage manager database comprises a plurality of data fingerprints;
• a deduplication database media agent comprising an electronically stored deduplication database;
• and
• a media agent comprising computer hardware configured to:
• receive an indication that a restoration of the deduplication database using a secondary copy of the deduplication database is complete;
• retrieve a first data fingerprint in the plurality of data fingerprints from the storage manager database, wherein the first data fingerprint is associated with a secondary copy job used to restore the deduplication database, wherein the first data fingerprint comprises an indication of a count of unique data blocks stored in a first secondary copy of a first file and an indication of a count of references stored in the first secondary copy of the first file that reference data blocks stored in other secondary copies, wherein execution of the secondary copy job resulted in generation of the first secondary copy of the first file;
• retrieve a second data fingerprint from the deduplication database media agent, wherein the second data fingerprint is associated with the secondary copy job used to restore the deduplication database;
• compare the first data fingerprint with the second data fingerprint to determine whether the first data fingerprint and the second data fingerprint match;
• and
• transmit an instruction to the deduplication database media agent to rebuild the restored deduplication database using the first secondary copy of the first file in response to a determination that the first data fingerprint and the second data fingerprint do not match.
