A copy older than one day is not deleted, acronis. Why?

Question

Backup

I use Acronis backup & recovery 11.5 I
created a backup plan and specified a backup plan in it, that is, "Delete backups older than 1 day"

Why do backups remain and are not deleted?
Thanks

Answer 1

Backup Method
=== Scheme: Simple
Change to Custom, there is a way to delete by prescription, and in the absence of free space.
With "Simple" hard clogged and you're without backups for weeks.
