virtual machine – Archive hpyer-v VMs to AWS glacier

hi I need to schedule automatic weekly archive hyper-v based VMs to amazon S3 Glacier storage for a single windows 2019 host machine with 3 VMs. I am familiar with vendors such as Veeam which provide costly solutions. Usually these are subscription based, requiring minimimum 5-10 licenses and cost $700 or more per year. Is there a cheaper (possibly perpetual licence), yet robust & simple solution for my needs.

Thanks in advance.
