Mac backup 0% complete, 'Backup now' is grey, says will complete in 1 sec but no movement.

Hi charibancho, thanks for bringing this to our attention.

How long did you give the computer time to complete the migration for the Dropbox Backup feature? 

It can take time to move the specified folders into the Dropbox folder to back them up.

This will help me to assist further!

Hey jwnicholsdds - sorry to jump in here, but can you let us know the exact status and version of the desktop app as shown in your menu bar?

If you clarify your device's OS version and if you've tried any of the troubleshooting steps mentioned in the OP, I'd appreciate it. 

I have the same problem about a year after the others in this thread have posted. Opened a support ticket.

Is anything being done to fix this?

I just started a trial mostly for the backup feature and it is disconcerting that it is not working right out of the gate.

Will await for a response but if this isn't solved in the next week I will cancel my trial and move to Google Drive.

I have the same issue now in April 2025... 0% backed up, updating X files / sometimes "complete" and still 0 bytes updated... It seems this has not been solved in over two years, then why even keep offering the Backup as a service if it doesn't work? Like others, this is why I'm trialing Dropbox, but no way am I going to keep paying. And before you ask, it's the latest update of everything... MacOS 15.4.1, Dropbox 222.4.5042, firewalls checked, multiple reboots, etc. Any recommendations?

Hi Nancy,
Thank you for picking this up! This is the screenshot from the status (Done, 0 bytes - the SSD is nearly 900GB in reality). I can't send you the status, though I'm afraid, as I have deleted it and started manually uploading folders to the browser one by one, as it seems to work better, even though it's tedious. But I am very happy to try any recommendations you have. The status used to be like "Extreme SSD - 68 GB - 0 bytes, 0% backed up ... 4562 files updating" and the files would tick along, then jump up in number again, but after a day of syncing, there was nothing in the backup and it was still 0%.
Best,
Charlie

P.S. I have a network monitor, so I can see traffic - and there wasn't a lot of traffic happening - for a while I thought Dropbox was just scanning local files before starting the upload. Currently with the manual upload, the upload traffic jumps to 10MBps as the files go up (and they actually show up).
