About NetBackup for Oracle schedule properties using Oracle Intelligent Policy

This topic describes the schedule properties that have a different meaning for Oracle Intelligent Policy backups than for file system backups. Other schedule properties vary according to your specific backup strategy and system configuration. Additional information about other schedule properties is available.

See the NetBackup Administrator's Guide, Volume I.

Table: Description of schedule properties

Property	Description
Type of backup	Specifies the type of backup that this schedule can control. The selection list shows only the backup types that apply to the policy you want to configure. See Oracle backup policy types.
Schedule type	You can schedule a backup in one of the following ways: Frequency This setting is used only for scheduled backups. It is not used for user-directed backups. Frequency specifies the period of time that can elapse until the next backup or archive operation begins on this schedule. For example, assume that the frequency is 7 days and a successful backup occurs on Wednesday. The next full backup does not occur until the following Wednesday. Typically, incremental backups have a shorter frequency than full backups. Calendar This setting is used only for scheduled backups. It is not used for user-directed backups. The Calendar option lets you schedule the backup operations that are based on specific dates, recurring week days, or recurring days of the month.
Retention	Specifies a retention period to keep backup copies of files before they are deleted. The retention period for an automatic schedule controls how long NetBackup keeps records of when scheduled backups occurred. Set the time period to retain at least two full backups of your database. In this way, if one full backup is lost, you have another full backup to restore. The type of schedule you select affects the retention period as follows: Frequency-based scheduling 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 at least 2 weeks. The NetBackup scheduler compares the latest record of the automatic backup schedule to the frequency of that automatic backup schedule. This comparison is done to determine whether a backup is due. So if you set the retention period to expire the record too early, the scheduled backup frequency is unpredictable. However, if you set the retention period to be longer than necessary, the NetBackup catalog accumulates unnecessary records. Oracle is not notified when NetBackup expires a backup image. Use Oracle RMAN repository maintenance commands to periodically delete expired backup sets from the Oracle RMAN repository. Calendar-based scheduling The retention period setting is not significant for calendar-based scheduling.
Multiple copies	If you want to specify multiple copies of a backup for the policy, configure Multiple copies on the application backup schedule.
Accelerator forced rescan	This option instructs NetBackup to re-copy all the data files to the share. This option is only available when Whole Database - Datafile Copy Share is selected in the Backup Selections tab and the Use Accelerator option is selected in the Attributes tab. This option forces the creation of a new set of database data file copies. When this option is not selected, the data file copies in the share are updated using an incremental backup. The incremental backup contains only the changed blocks since the last full backup.
