It's great to see you here, @Jacknlacosta,
I want to make sure this issue is addressed and you're able to backup your company file successfully. Before that, I need to verify if you are using MacOS Big Sur. We currently have an ongoing issue with this operating system where customers get an error "BACKUP FAILED. Quickbooks was unable to back up your company file. QuickBooks could not copy the company file."
The suggested workaround for this is making sure you're on the latest macOS version 11.4. Then you'll need to delete to the PLIST* files from the User and System folder. This way, all preferences will revert back to its default settings and you can create the back up without any issues.
The steps are as follows:
Deleting User PLIST
- Go to the Finder menu.
- Hold down the Option key, then select Library.
- Open the Preferences folder.
- Find PLIST files that contains com.intuit.QuickBooks20XX, then move them to the Trash.
Note: XX is the QuickBooks version you’re using.
- Empty the trash.
Deleting System PLIST
- From a new Finder window, open the Macintosh HD.
- Go to Library, then Preferences folder.
- Find PLIST files that contains com.intuit.QuickBooks20XX, then move them to the Trash.
Note: XX is the QuickBooks version you’re using.
- Empty the trash.
I also recommend contacting our QuickBooks Mac Support to add your account to the list of affected users if the workarounf doesn't work. Our representatives will add your email to our notification loop to receive updates about the issue.

Let me know how it goes. I want to keep track of this backup topic and make sure it gets taken care of. I'm also here if you ever need further help with any other things in QuickBooks. Have a good one!
