The following table describes the parameters used by backup missions to specify the retention period of a backed up CDAM file:
Table 163 Parameters for Changing Backup Mission Retention Period
Parameter |
Description |
|---|---|
# OF DAYS TO KEEP |
Specifies how many days must elapse from the backup date to the expiration date. |
# OF GENERATIONS TO KEEP |
Specifies how many subsequent generations (executions) of the backup mission must be produced until the generation expires. |
You can specify either one (but not both) of these parameters in the backup mission definition screen. If you need to change from the # OF GENERATIONS TO KEEP method to the # OF DAYS TO KEEP method, use a new backup mission (that is, statement DO BACKUP in the decollation mission definition must refer to a new backup mission name). If the same backup mission is used, an error message is displayed and the backup mission ends NOTOK.
