Zoho Creator backup doesn't backup custom deluge script logic from pages, validations, etc?

I backed up and downloaded my application and looked through the files. It looks like pages and validations, etc (deluge scripts) are not backed up? I am shocked to see this as I invest countless hours into developing these scripts, why are they not backed up as part of the regular backup process? Is there any way to back these up all at once or do I have to manually back up each of these on my own?
