Backup into iCloud from Windows

Hello everyone,

my wife has a 2TB Apple iCloud plan. Thus, I thought about piggybacking onto it to save my backup there.

I set everything up (iCloud for Windows, Kopia, Policy, Snapshot) and started the backup process. Everything was working pretty fine, until I got a notification that my C drive has no capacity anymore. I checked it and saw that the combined backup of my selected folders took up ~400GB locally on my C drive.

Is there a way to save the files with Kopia only in the iCloud and not locally? Can I just delete them locally, or will Kopia freak out if they are not present locally and try to request them so they end up on my drive again anyway?

I currently can’t complete the snapshot as there is not enough space.

Greetings,

Niklas
