HIGHLY REUSABLE DEDUPLICATION DATABASE AFTER DISASTER RECOVERY

摘要

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.

主权项

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; andfor 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.
