Teradata Tools and Utilities

The Teradata Database node that is designated as the Appliance Backup Utility server controls backup and restore operations, working as a master to Appliance Backup Utility clients that manage the data streams during backup and restore operations.

A Backup All job is configured to run multiple data streams, which are equal to the number of Appliance Backup Utility clients configured to the Appliance Backup Utility. For every job data stream, a backup file is created on the storage device. There might be multiple disk partitions or directories designated as destination paths for the backup stream. The sum of all backup files created by the data streams equals the entire backup of your Teradata Database. If one or more of these files are deleted or corrupted, you will not be able to restore your Teradata Database backup.

You can configure a Backup Selected Objects job to run one or more data streams. Configure one stream only if you know the length of time the backup will take and if the objects or group of objects are small. Optimal backup throughput is only achieved with full parallelism where all Appliance Backup Utility clients are used.
