No problem. Yes, I'm still learning 
Ok. Yes, in this case, I want it to be global, because I have a lot of apps that I need to create backups from on a regular basis.
Not really. I have 3 actions, just like you do:
1 - Set a Variable inside a macro, something I will not have to change at all.
2 - The action to run the variable
3 - The action to create the folder
You have 3 actions as well: orange, green, gray.
Now the difference I see on my approach, is that I don't have to worry much about filling out 2 fields ("Filter" and "To") or remember what those are supposed to be. All I need to do is go to the Execute Macro dropdown menu > "Select Macro by Name" > type "Current Date" and that's it. I'm good to go.
Your approach is also useful at least for me to learn another new thing that could be useful in another scenario. In this case, it seems that my approach (unless there's something I'm missing in terms of running into issues) is faster and easy to remember.
So true and it's through seeing other people's approach that we end up learning new ways of achieving the same results, but sometimes in a better way. Been learning a lot from reading other people's threads
