Veeam 9 vmware template backups

I need to backup my templates.  Doing some reading, my understanding is that template backups in Veeam do not use cbt (instead whole file is read each time) and hot add (instead run as network backup) which can make them take much longer.  I read a blog on adding some scripts to the job so the template is converted to vm before backup and then back to template at end.  Veeam support indicated not really a need to do that, but i'm wondering for the sake of performance and my backup window if I should convert the templates to vms, leave powered off as vms and only convert to template when I need to deploy new vm's.  Seems like that would simplify the process and difference between backuping up vm vs template.  

Thoughts? Real world practices?

Thank you.
