Some good questions, and to be honest I don't know 100% for most of these as they are about things to do with with how the Apple iCloud sync process works.
I'm particular I'm not sure how iCloud handles symbolic links as they won't necessarily work on other devices. I imagine that if you only have a symlink in iCloud to a directory on your computers storage that might not work. Symlinking to the iCloud directory is probably going to work better.
A search on the Apple forum shows differing opinions as to whether files in iCloud are backed up via Time Machine. I personally use Keyboard Maestro to kick off backing up all my org files to a zip file on Dropbox daily.
To keep stuff in sync between beorg and my desktop, I have symlinked the org file from icloud to my home dir:
I have a few questions:
What's the best practice here?
