AWS Backup: Backup window

Hello,

In my organization there is some uncertainty about the backup window of AWS backup. In the documentation I couldn't find an absolutely clear answer, so now I'm here!

Some teams want to be more in control of when a backup of their system is made, so they want to create a smaller backup window. But they are afraid that when this window is too small, no backup is made. Is there information about how small a backup window can be and is there a risk of no backups taken if the window is too small?

Thanks for your answer!
