@Rose-A,

Thank you for the reply.  YES, I followed these steps from the previous poster, and this is how I got my backups working.

HOWEVER, even though I have specified in QB to limit the number of backups, it no longer does this.  It USED to (Version 2019 and lower) rename previous backups as SBU_1, SBU_2, SBU_3, etc....however, now it just always creates the new "SBU_0" backup and does NOT rename/delete old ones.

I am a bit frustrated because it appears that the moderators here do NOT read the full context of the question before reply.
