The following example shows a typical backup schedule during which catalogs are regularly discarded to ensure that there are never more than 30 catalogs on the minidisk at any particular time.
You have specified that catalogs are created by backups run with these characteristics:
|
Backup frequency |
Backup type |
Auto-discard period |
|
Monthly |
Full |
1 year |
|
Weekly |
Full |
8 weeks |
|
Daily |
Incremental |
14 days |
These backups run on this schedule:

Every Saturday except first Saturday of each month
Every day except Saturday
These characteristics and schedule ensure that the number of catalogs on the catalog minidisk at any one time is never greater than 30:
