sorry for asking again. I'm using Akeeba on many Wordpress sites. There I do on some sites daily, on other sites weekly backups. But on all sites the backups from the first day of the month should not deleted.
This works on most of the sites perfect. But now I found some sites where it does not work. The backups from the 1st of each month are deleted. I tried to compare sites where it is working and sites where it is not working, but all are using the same settings.
Attached you'll find a screenshot of the quota settings and the logfile where a backup from the 1st of the month is deleted.
