Keep backups: Monthly
This step defines the retention rule for monthly backups. The cleanup task will run after each
monthly backup and delete all monthly backups that are older than you specify. The monthly
backups' retention period cannot be less than the weekly backups' retention period. It is usually
set several times longer. You have the option to keep the monthly backups infinitely.
The resulting archive: ideal
Assume you select to keep daily backups for 7 days, weekly backups for 2 weeks and monthly
backups for 6 months. Here is how your archive would appear after the backup plan is launched if all
the backups were full and so could be deleted as soon as the scheme requires.
The left column shows days of the week. For each day of the week, the content of the archive after
the regular backup and the subsequent cleanup is shown.
"D" stands for the backup that is considered Daily. "W" stands for the backup that is considered
Weekly. "M" stands for the backup that is considered Monthly.
