To change a retention period

1. In the NetBackup Administration Console, in the left pane, expand NetBackup Management > Host Properties > Master Servers.
2. In the right pane, double-click on the master server you want to modify.
3. In the properties dialog box, in the left pane, click Retention Periods.
4. Select the retention level to change.

   By default, levels 9 through 100 (except level 25) are set to infinite. If the levels are left at the default, there is no difference between a retention level of 12 and a retention level of 20. Level 9 cannot be changed and the retention period is always set to infinite. Retention level 25 also cannot be changed and the retention period is always set to expires immediately.

   See Retention Periods with end dates beyond 2038, excluding Infinity.

   The dialog box displays the names of all schedules that use the selected retention level as well as the policy to which each schedule belongs.

5. Type the new retention period in the Value box.
6. From the Units drop-down list, select a unit of measure (days, weeks, months, years, Infinite, or Expires immediately).

   After you change the value or unit of measure, an asterisk (*) appears in the Changes Pending column to indicate that the period was changed. NetBackup does not change the actual configuration until the administrator accepts or applies the changes.

7. Click Impact Report.

   The policy impact list displays the policies and the schedule names where the new retention period is less than the frequency period. To prevent a potential gap in backup coverage, redefine the retention period for the schedules or change the retention or frequency for the schedule.

8. Do one of the following:

   • To discard your changes, click Cancel.

   • To save your changes and leave the dialog box open to make further changes, click Apply.

   • To save your changes and close the dialog box, click OK.
