Schedule properties

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.

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

Specifies a retention period to keep backup copies of files before they are deleted. The retention level also denotes a schedule priority within the policy. A higher level has a higher priority. 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. For example, if your database is backed up once every Sunday morning, you should select a retention period of at least 2 weeks.

The retention period for an application backup schedule refers to the length of time that NetBackup keeps backup images. The retention period for an automatic schedule controls how long NetBackup keeps records of when scheduled backups occurred. For example, if your database is backed up once every Sunday morning, you should select a retention period of at least 2 weeks.

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.
