Folder Management Help Needed

Hi all,
I have an app that does hourly backups to a folder 'MyBackups' using a folder name like 'Backup A' 'Backup B' etc... Sometimes this process deliberately is halted from time to time.
Goal:
This main backup folder 'MyBackups' Will fill up overtime. My goal is to make sure that the most recent backup folder - will always remain in this folder (whether the main app process is active or stopped) and all the other older ones can be moved elsewhere or deleted.
So I tried rules like:
if all match:
sub-file/folder count > 1
continue matching rules
then rule 2
- if date created is not in the last 1 day
- move to folder 'old'
problem: it seems to move all the folders including the one I want to keep in the main 'MyBackups' folder
Q: how can I fix this so that the latest folder Will remain is that my backup folder and all the other ones will get moved
