    Server targets added, changed, or deleted data only, skipping files that have previously been backed up and are unchanged. In addition, Barracuda Networks has developed an innovative deduplication method of “bit differential analysis” that breaks backed-up data into parts, which are then fingerprinted and compared to all parts on record.

  • Page 9: Microsoft Application Support

    Microsoft Application Support The Barracuda Backup Agent provides the ability to back up these Microsoft server applications: Exchange, SQL, Hyper-V, and System State. In each case, a full restore of these environments allows an organization to recover in the event that their environment has been corrupted or destroyed. Additional restore options allow Exchange to be restored to a recovery group or database, or for Exchange or SQL to be restored to a flat file.

If it is disabled, nothing is sent from the Barracuda Backup Server to the destination until the feature is enabled or until 24 hours have passed. This allows you to move the destination system to a remote location, say, without getting backup errors.
