Backup jobs archive objects from a Teradata source system to a target group. Target groups are defined by a BAR administrator in the BAR Setup portlet or command-line interface.

The BAR Operations portlet allows you to migrate the object list from an existing ARC script into a backup job. Objects in that list that exist in the specified source system are automatically selected in the object browser when a new job is created from the migrated ARC script.

When you run a backup job for the first time or when you change the target group for a backup job, all data from the specified objects is archived. After this initial full backup, you can choose the backup type:
  • Full: Archives all data from the specified objects
  • Delta: Archives only the data that has changed since the last backup operation
  • Cumulative: Archives the data that has changed since the last full backup was run
