1.	What do you know about the Deduplication Database in the context of Commvault?
Answer» In Commvault, WHENEVER a storage policy with deduplication is implemented, signatures are generated for data blocks during BACKUPS, COMPARED, and then stored in the deduplication DATABASE (DDB). The DDB backup subclient automatically protects DDBs. All active DDBs controlled by the MediaAgent that hosts the DDB are backed up by this subclient. You can set up a reconstruction task for an automatic or on-demand RESTORE of the DDB from the DDB backup in the event of DDB failure. The storage metadata can then be used to rebuild missing records.
