Two Partitions on the same iCloud server

Hi

I had created 2 partitions on a single server. one has stopped allowing files being saved after a while.Do they have their own limits to storage capacities which I’m not aware of ? How do i change them?

Regards
Jim

Have you checked with Apple? https://www.apple.com/icloud/

iCloud is built into every Apple device. That means all your stuff — photos, files, notes, and more — is safe, up to date, and available wherever you are. And it works automatically, so all you have to do is keep doing what you love. Everyone gets 5GB of free iCloud storage to start, and it’s easy to add more at any time.

Thanks. All my Imac files are back-up on the cloud.

Thought i will back up on a WD home server of my own again, just in case
