The Retention periods list displays a list of the current definitions for the 25 possible levels of retention (0 through 24). By default, levels 9 through 24 are set to infinite. Retention level 9 is the only level that cannot be changed and remains at infinite.

Note that if left at the default, there is no difference between a retention level of 12 and a retention level of 20, for example.

The Schedule Count column indicates how many schedules currently use each level. If the retention period is changed for a level, it affects all schedules that use that level.

The Changes Pending column uses an asterisk (*) to indicate that the period has been changed and not applied. NetBackup does not change the actual configuration until the administrator clicks Apply or OK.
