One project I recently led is the migration of data from an old EMC Clariion to the new EMC VNX. Data Migration Using PowerPath Migration Enabler This entry was posted in Backup and Disaster Recovery, Technical How-to on Maby admin. Both one-way and two-way authentication require the client to be knowledgeable about certificates.Р”Р‡or example: # ddboost clients add encryption-strength high authentication-mode anonymousР”В¬lient Encryption Strength Authentication Mode A client trying to connect by using a weaker authentication setting will be blocked. The authentication-mode option is used to configure the minimum authentication requirement. The specific cipher suite used is either ADH-AES256-SHA, if the HIGH encryption option is selected, or ADH-AES128-SHA, if the MEDIUM encryption option is selected. This command can enable encryption for a single client or for a set of clients. To enable in-flight encryption for backup and restore operations over a LAN, run the following command on the Data Domain: # ddboost clients add client-list

When configured, the client is able to use TLS to encrypt the session between the client and the Data Domain system. In-flight encryption enables applications to encrypt in-flight backup or restore data over the network from the Data Domain system. In contrast, if Oracle RMAN encryption is used, data will not be deduplicated because they will be encrypted first, thus deduplication ratio will suffer. Since the encryption happens after deduplication and before the segment leaves the Oracle server (in-flight encryption), deduplication ratios will not suffer on the Data Domain system. To secure Oracle database backup from a DB server to a Data Domain system, DD Boost for RMAN encryption can be enabled so that RMAN backup data can be encrypted after deduplication at the Oracle server and before transmitting across the network.
