Schedule properties for Oracle script-based policies

This topic describes the schedule properties that have a different meaning for database 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 an automatic backup in one of the following ways: Calendar The Calendar option lets you schedule the backup operations that are based on specific dates, recurring week days, or recurring days of the month. Frequency The Frequency specifies the period of time that can elapse until the next backup 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.
Retention	Clients for use with scripts: The retention period for an application backup type schedule refers to the length of time that NetBackup keeps backup images for stream-based backups. The retention period for an automatic backup type schedule refers to the length of time that NetBackup keeps backup images for proxy based backups. Oracle Intelligent Policy (OIP): The retention period for an automatic backup type schedule refers to the length of time that NetBackup keeps backup images for all backup types (stream-based, proxy, etc.) The Oracle database also has retention settings for backup images in the RMAN catalog. As a general recommendation, the NetBackup retention of a backup image should be longer than the database retention of the same backup image.
Effect of type of schedule on retention period	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 more than one week. 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. Oracle XML export operations create archives for long-term storage and recovery. Set the retention level to a period of years or to infinity. Calendar-based scheduling The retention period setting is not significant for calendar-based scheduling.
