If I need a policy like this:
Full Backup - once a month (first Sunday at 02.00) retention 30 days
Diff - every day (at 02.00 except first Sunday) retention 5 days
Now I set 30 days as storage policy default for Full backups, and in schedule policies for Diff backups in Media - Job Retention I set 5 days. But I still see the content of diff backups older than 5 days. How and where can I set the above policy correctly?
Another question is how to set the deletion policy by the number of backup points. That is, I need one backup. When creating a new one, delete the old one without reference to days.
