Select the Initial Configuration Method

Thales supports two methods for the initial configuration of Teradata Database devices:

• Standard Initialization Method

  This method configures devices for initial encryption of existing clear-text data on the database devices. The time required to encrypt may take hours or even days, depending on the volume of data, the number of database devices and nodes, and the bandwidth of the storage back-end of database devices. For details, see Initialize and Guard the Database Devices Using the Standard Initialization Method.

• Backup/Restore Initialization Method

  This method skips the initial encryption step but requires a full backup of the database and the engagement of Teradata Customer Support to assist you with some configuration steps at the Teradata database level in preparation for the full restore of the database after the database devices are protected. The length of time required for this method depends on the length of time it takes to back up, and then fully restore, your Teradata database. For details about using this method, see Initialize and Guard the Teradata Database Devices Using the Backup/Restore Method.
