i've got the email with the link for dowloading the product when at home, so i could not resist and installed it on my own desktop pc, which i use just for fun (facebook and youtube

It has 4 GB Ram.
I have been a bit surprised that sql express was installed, and using >300MB of memory even while backups were not running.
IMHO that's a bit heavy for small desktops, laptops and so on, sorry.
I've been using i.e. this one: http://www.aomeitech.com/aomei-backupper.html, which is able to backup machine while normally running, but does not need a sql server permanently installed on it....
I understand VeeamEndpointBackup has much more functionalities but, at least in my own pc at home, i don't need them, and i prefer to "keep it light".
