The properties for the Application Backup and Automatic Backup schedules are described in the following table. Be aware when you are specifying schedule properties that some properties have a different meaning for database backups than for regular file system backups.
| Property | Description |
|---|---|
| Type of backup | The type of backup property specifies the type of backup that this schedule controls. The selection list shows only the backup types that apply to the policy you are configuring. For more information see the Description of Backup Types for Teradata table. |
| Frequency | The frequency property specifies the period of time that will elapse until the next backup or archive operation can begin on this schedule. For example, if the frequency is seven days and a successful backup occurs on Wednesday, the next full backup will not occur until the following Wednesday. Normally, incremental backups will have a shorter frequency than full backups. This setting is used only for scheduled backups, and not for user-directed backups. |
| Calendar | The calendar property allows scheduling of backup operations based on specific dates, recurring week days, or recurring days of the month. This setting is used only for scheduled backups, and not for user-directed backups. |
| Retention |
Frequency-based scheduling
The retention period for an Application Backup Policy schedule refers to the length of time that NetBackup keeps backup images. The retention period for an Automatic Backup schedule controls how long NetBackup keeps records of when scheduled backups have occurred. The NetBackup scheduler compares the latest record to the frequency to determine whether a backup is due. This means that if you set the retention period to expire the record too early, the scheduled backup frequency will be unpredictable. However, if you set the retention period to be longer than necessary, the NetBackup catalog will accumulate unnecessary records. Therefore, set a retention period that is longer than the frequency setting for the schedule. For example, if the frequency setting is set to one week, set the retention period to be more than one week. Calendar-based scheduling The retention period for an Application Backup Policy schedule refers to the length of time that NetBackup keeps backup images. The retention period for an Automatic Backup schedule controls how long NetBackup keeps records of when scheduled backups have occurred. However, this setting is not significant for calendar based scheduling. |
| Multiple copies | If you are licensed for the Inline Tape Copy feature and want to specify multiple copies for your NCR-Teradata or Teradata policy, configure Multiple copies on the Application Backup schedule. |
Other schedule properties vary with specific backup strategy and system configuration. Consult the NetBackup System Administrator’s Guide for detailed explanations of the schedule properties.
