Hello,
In other words, can I use iCloud as a back-up for a huge file without having that file sync on my space-limited laptop?
(As things work right now, the files in iCloud are also on my main computer, a Mac Pro, and my laptop, a Macbook Pro.)
Thanks.
Maybe I'm not understanding icloud fully (I just started using it), but as far as I know only the Documents and Desktop folder syncs automatically and requires you to have the file on your device and the cloud at the same time (synced). Plus any app that supports icloud (i.e. pages). Not all apps use icloud though (like scrivener for example).
So I think you are asking if you can upload a file to icloud, without it having to be on your computer? Yes, at least in my experience you can. In the cloud (in finder), Just create a folder outside of Desktop folder or Documents folder and drag and drop.
I have the same need as you, because I only have 128gb of space. I'm into music creation, so what I do is I install all my apps and plugins which take up a good chunk of the hard drive...then I only keep a few projects I'm currently working on, on my hard drive, then I upload all my other Work in Progress projects manually to icloud and when I'm finished with a project I leave them in the cloud and delete them from my computer...so that I can start a new project. Garageband can do this automatically but I found I have to do it manually with Logic pro. These project files in uncompressed form can be hundreds of megabytes each so offloading to icloud is a must.
And once i've finished a project, I upload it to the cloud and delete it from my logic pro folder. The logic pro folder on my computer isn't synced so whatever I delete on my hard drive doesn't affect what I manually uploaded to the cloud.
Now if I had these projects on my desktop background or in my Documents. They would be synced everywhere I had an icloud account.
I have reinstalled the operating system several times and I have deleted projects without it affecting anything in the cloud.
I just started paying and using the 50GB plan so I'm still learning about it but I'm pretty sure you just create folders outside of the Documents and Desktop folder.
If these are just a few really big files, best to do this manually like I do.
I hope this helps.

edit:
Someone said icoud can't be used as a backup solution, but that's one of the ways I use it. Why else would they offer up to 200gb of upload? Some people might say "why not buy an external hard drive" and just backup that way, but I just like the convenience of the cloud. I'd rather pay $.99 a month and get 50gb (more than I need right now) then buy a $50 1TB hard drive only to have it fail months down the road.
I will say though I have had problems with what some people call "hanging" (where you upload a file and it just pauses for no particular reason). So if this continues I might look into a 3rd party solution like dropbox for reliability. I haven't lost anything in the cloud yet, but sometimes the upload has paused.
