Do you have local (non-cloud) backups? If yes, that's great, but otherwise I wouldn't recommend a cloud-only (or a single backup) approach to storing important data.
But I plan on also doing backups with blackblaze or somewhere similar.
My plan for the cloud server is just to have a central place to access all my (and my wife's) files from any device. But then my problem is, as I mentioned earlier, how do I bulk edit/organize those files using desktop software?
It feels like you're looking for something like git-annex (https://git-annex.branchable.com/). I've never used it but read a bit about it, here's how you would use it:
- Install git-annex on your cloud
- Tell git-annex that you have a remote there
- Do your stuff on your local drive, push to the cloud when it's done
- If some of the files are not needed locally, tell git-annex to drop them from your local drive. git-annex knows that there is another copy in a safe storage
- If you want to work on some files you don't have, ask git-annex to transfer them to you.
