Teradata Tools and Utilities
The Appliance Backup Utility provides a simple way for Teradata appliance platforms to back up the Teradata Database to a disk file system, then restore the backup datasets to the same Teradata Database. You can also use the Appliance Backup Utility to copy Teradata Database object data of one instance to another instance of a Teradata Database. You must have the Appliance Backup Utility installed on each Teradata Database node for copying data to another instance. Data is backed up to network-attached disk storage.

Depending on the disk storage you have selected, you might be responsible for configuring and maintaining the disk storage. In that situation, Teradata Corporation support is limited to Appliance Backup Utility functionality on the node. Installation, configuration, and maintenance services for disk storage can be purchased from Teradata Corporation for the Teradata Managed Storage Server (TMSS) Model 855NAS-14D, and are required for the Teradata Data Domain 4200 (DD4200).

For complete data protection, copy data from disk storage to tape through any third-party backup application. Backing up then becomes a two-step process: backing up to disk storage, then copying to tape storage, disk, or Virtual Tape Library (VTL) with a third-party application. To restore, use the original file names to copy the data back to disk storage, then restore to the Teradata Database.

Using the Appliance Backup Utility GUI, you can:
  • Back up DBC and user data with the Backup All option
  • Restore the latest DBC backup with the Restore Latest option
  • Back up selected database objects such as triggers, macros, or tables with the Backup Selected Objects option
  • Restore selected database objects with the Restore Selected Objects option

The Appliance Backup Utility software components are the Appliance Backup Utility server, client, and GUI.

What is an Appliance Backup Utility Server?

The Appliance Backup Utility server is a Teradata Database node that:
  • Has Appliance Backup Utility server, client, and GUI software
  • Is connected to disk storage
  • Is the node on which you run the configuration script

The Teradata Database node that is designated as the Appliance Backup Utility server also functions as the GUI and an Appliance Backup Utility client. There must always be an active Application Backup Utility client on the Teradata Database node that is selected to run the Application Backup Utility server.

Install and configure only one Appliance Backup Utility server.

What is an Appliance Backup Utility Client?

An Appliance Backup Utility client is a Teradata Database node that you have specified as a client and has:
  • Active Appliance Backup Utility client software
  • A connection to disk storage
  • Passive Appliance Backup Utility server software, which is not used unless the server is manually switched in failover recovery.

What is an Appliance Backup Utility GUI?

The Appliance Backup Utility GUI allows you to control the backup and restore operations of the Appliance Backup Utility. You can install the GUI on any node or PC workstation that is connected to the Appliance Backup Utility server.

What Are Streams?

The data that is backed up to disk storage consists of one or more streams. Each stream is a portion of the entire backup job. Increasing the number of streams can yield increased throughput through parallel processing, up to the threshold of the connections to the disk storage device. Teradata Corporation normally recommends one stream per Teradata Database node. However, nine streams per Teradata Database node is recommended when using the DD4200 target device, or one stream per Teradata Database node when using the TMSS 855NAS-14D.
