I am unable to make a Time Machine backup on my MacBook Pro running macOS Sonoma

When my Mac attempts to make a Time Machine backup, I get the following error message (two lines):

"Backup Not Completed

Some of the files on your Mac cannot be backed up until Cloud Files syncing has completed."

This occurs absolutely every time my Mac attempts to make a Time Machine backup, now that I have upgraded to Sonoma 14.0 (23A344).

I am in the middle of help from a senior advisor at Apple and am expecting a callback very soon.

I had the same problem. After almost 10 hours, the Finder showed that the iCloud drive was synced. However, I still could not backup and received the same error message about syncing has to complete.

Hmmm.... I had made an alternate login on my computer that I used with a language I was studying. I had not logged into that user for several months.

I logged in to that user account, went to settings and TURNED OFF using iCloud for that user's account. I was warned that documents on the cloud would be deleted. Clicked okay. Logged out, logged in to my normal account and Time Machine backup started immediately. It appears that Time Machine was waiting for this "other" account to finish syncing to the cloud before it could complete a backup. ( Instead of turning off iCloud for this user, I could have waited for Finder to finish syncing this user's account, then logged out, log in to my normal account)

looks like Mac OS 14.1 RC did fix/address NAS TM encrypted backup's ... at least that's what my testing shows ...

My icloud settings are synced (not that big - I've got dropbox for most) and the problem still remains...

Seriously: Apple was not able to fix the issue with 14.1? That is bad, really bad! Do I have to wait for 14.999 to upgrade to Sonoma (after downgrading to Ventura just because of that issue)?

How can anybody be patient for days unable to backup?

I have the same issue. I hope this will be fixed by Apple. I have left the automatic update on. I am not happy with apple on this issue, backup is absolutely necessary. I don't want to roll back.
