schedule VCSA 6.5 backups..

I was wondering if there is any script or similiar available to schedule VCSA backups to a FTP server.

I tried multiple stuff but none seems to be working . Adapted a Bash script but it doesn't give me output as below

VMware vSphere 6.5 Documentation Library

Tried Backup vCenter Server Appliance (VCSA) 6.5 Using PowerShell – VCDX56 

But https://www.brianjgraf.com/2016/11/18/vsphere-6-5-automate-vcsa-backup/  the link at end on guthub is missing . Page missing...

Is there a way to schedule these backups for VCSA.
