Does Time Machine do backups of the files on iCloud?

Hi all,

I just read that:

"iCloud Drive also allows you to offload data from your Mac onto the

cloud if your Mac is running low on storage. This basically means that

all files that you rarely use are backed up on the cloud and deleted

from your system. However, a file shortcut is still present in the same

location on your Mac, and in the case that you need to access it again,

the original file is downloaded and opened on your system immediately.

This allows you to save some crucial storage space on your Mac."

"What's more, if you're already using iCloud Drive, you'll need to

download all offloaded data onto your Mac to back it up using Time

Machine."

Are these files downloaded automatically while performing a Time Machine

backup, or do I have to tell my Mac to download them before starting the

Time Machine backup? If I need to download them before the backup, how

do I tell my computer to download them all at once? To download the

files one by one would take forever.

And, I have enough space on my internal HD, but many files are in the cloud

anyway. From what I have observed, it's the files I haven't used for a

while, but the choice of the files is rather random. Can I configure my

Mac (or iCloud Drive) so that all files are always on my computer?
