I too am having problems with Time Machine backups on my Unraid server. AFP is off. SMB has Enhanced macOS interoperability enabled. My backup share is Exported as Time Machine. Time Machine Backups are fine with these settings on 6.7.2. Unraid 6.8 and above all have the same slow backup problem. Backups take days and more or less never complete.
Time Machine unbelievably slow
