Yes, I am using rsync from/on my Linux Mint machine, when trying to communicate with another computer (w/ TrueNAS) that it’s time to backup my OS.

But, I didn’t know about the folder ignoring flag, that is helpful. Thank you for the info. I will look into that before I backup again.

That’s a great point. I will add that info now.

Rsync keeps telling me that my Linux Mint installation is too big to backup on into my TrueNAS machine. And the culprits are my Steam games, especially Cyberpunk 2077 at 66 GB. fml
