HIGHLY REUSABLE DEDUPLICATION DATABASE AFTER DISASTER RECOVERY
First Claim
1. A networked information management system configured to verify synchronization of deduplication information, the networked information management system comprising:
- a data storage database comprising a plurality of first archive file identifiers at a first time;
a data storage computer in communication with the data storage database, the data storage computer comprising computer hardware configured to receive an indication that the data storage database is being restored to a version of the database as of a second time before the first time such that the data storage database comprises a subset of the plurality of first archive file identifiers that were present in the data storage database at the second time; and
a media agent executing on one or more computer processors and configured to;
receive a first instruction from the data storage computer in response to the data storage computer receiving the indication, wherein the first instruction instructs the media agent to stop scheduled secondary storage operations associated with a deduplication database, and wherein the deduplication database comprises a plurality of second archive file identifiers;
determine at least one second archive file identifier in the plurality of second archive file identifiers that does not correlate with any first archive file identifier in the subset of the plurality of first archive file identifiers; and
for each of the at least one second archive file identifier, instruct the deduplication database to prune an entry associated with the respective second archive file identifier.

Abstract
According to certain aspects, a method can include receiving, in response to an indication that a data storage database is being restored to a second time before a first time such that the data storage database comprises a plurality of first archive file identifiers associated at the second time, a first instruction from a data storage computer, where the first instruction instructs a media agent to stop scheduled secondary storage operations associated with a deduplication database, and where the deduplication database comprises a plurality of second archive file identifiers; determining at least one second archive file identifier in the plurality of second archive file identifiers that does not correlate with any first archive identifier in the plurality of first archive file identifiers; and, for each of the at least one second archive identifier, instructing the deduplication database to prune an entry associated with the respective second archive file identifier.

1. A networked information management system configured to verify synchronization of deduplication information, the networked information management system comprising:
-
a data storage database comprising a plurality of first archive file identifiers at a first time; a data storage computer in communication with the data storage database, the data storage computer comprising computer hardware configured to receive an indication that the data storage database is being restored to a version of the database as of a second time before the first time such that the data storage database comprises a subset of the plurality of first archive file identifiers that were present in the data storage database at the second time; and a media agent executing on one or more computer processors and configured to; receive a first instruction from the data storage computer in response to the data storage computer receiving the indication, wherein the first instruction instructs the media agent to stop scheduled secondary storage operations associated with a deduplication database, and wherein the deduplication database comprises a plurality of second archive file identifiers; determine at least one second archive file identifier in the plurality of second archive file identifiers that does not correlate with any first archive file identifier in the subset of the plurality of first archive file identifiers; and for each of the at least one second archive file identifier, instruct the deduplication database to prune an entry associated with the respective second archive file identifier. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A computer-implemented method for verifying synchronization of deduplication information, the computer-implemented method comprising:
-
receiving, in response to an indication that a data storage database is being restored to a second time before a first time such that the data storage database comprises a plurality of first archive file identifiers associated at the second time, a first instruction from a data storage computer, wherein the first instruction instructs a media agent to stop scheduled secondary storage operations associated with a deduplication database, and wherein the deduplication database comprises a plurality of second archive file identifiers; determining at least one second archive file identifier in the plurality of second archive file identifiers that does not correlate with any first archive identifier in the plurality of first archive file identifiers; and for each of the at least one second archive identifier, instructing the deduplication database to prune an entry associated with the respective second archive file identifier. - View Dependent Claims (10, 11, 12, 13, 14)

15. A networked information management system configured to verify synchronization of deduplication information, the networked information management system comprising:
-
a storage manager database comprising a plurality of first archive file identifiers at a first time; a storage manager in communication with the storage manager database, the storage manager comprising computer hardware configured to receive an indication that the storage manager database is being restored to a second time before the first time such that the storage manager database comprises a subset of the plurality of first archive file identifiers present in the storage manager database at the second time; and a deduplication database media agent comprising an electronically stored deduplication database and computer hardware configured to; receive a first instruction from the storage manager in response to the storage manager receiving the indication, wherein the first instruction instructs the media agent to stop scheduled secondary storage operations associated with the deduplication database, and wherein the deduplication database comprises a plurality of second archive file identifiers; determine at least one second archive file identifier in the plurality of second archive file identifiers that does not correlate with any first archive file identifier in the plurality of first archive file identifiers; and for each of the at least one second archive file identifier, instruct the deduplication database to prune an entry associated with the respective second archive file identifier. - View Dependent Claims (16, 17, 18, 19, 20)
