The remote desktops are having a mix of Windows based operating system along with Internet connection. They are not part of domain / workgroup. They have non-standard folders to be backed up. Need to have a disk-to-usb-cloud backup wherein Monday to Friday are retained for a week, Saturday backup retained for a month. Need to use in-built Windows tools and free cloud. I should should be able to monitor success / failure of each and able to access the cloud data.
