Schedule properties for SQL Server batch file-based policies
Each policy has its own set of schedules. These schedules initiate automatic backups and specify when a user can initiate operations. Some 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. See the NetBackup Administrator's Guide, Volume I.

| 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.

| You can schedule an automatic backup in one of the following ways: The option lets you schedule the backup operations that are based on specific dates, recurring week days, or recurring days of the month. The 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.

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.
Calendar-based scheduling
The retention period setting is not significant for calendar-based scheduling.
