Icloud backups not available

Hi

I accidently deleted my complete messages history with my daughter from my iphone and it turns out that I have no recent backups - or no backups at all..

However, when I look at my icloud account, I have used 2.67 GB for backup.

I can't see those backups on neither icloud nor the phone.

The phone says that it has used 0kB on backups for the phone.

So my question is: what is the 2.67 GB backup and how do I access it to see if I can use it for restore of the lost messages?
