Unable to make backup using Time Machine

iMac Retina 5k, 27-inch, late 2015

Catalina 10.15.1

Lately I checked Time Machine and realized that my last backup was 2 months old. I had used Time Machine Editor to make the incremental backups once a day.

I erased the external HDD and started a full backup. After a few unsuccessful tries I assumed an HDD problem and got myself a new HDD. Same problem. After at least 10 hours the backup is stuck at around 730GB of 900GB. The "remaining time" goes up and the backup never finishes. I swapped the USB port but again same result.

It's odd. You might try starting up in Safe Mode and see if that makes a difference.

Use safe mode to isolate issues with your Mac - Apple Support

EDIT: Oh and if you still have TM Editor please delete it for now.
