I wrote earlier that I have a Synology disc station on mr NAS. It fully supports my Mac’s time machine backups, whI have runs automatically, plus in the disc station, there’s a Synology app I also use for backing up my photo folders.
the only issue I have is that since upgrading the mac‘s O/S to Big Sur, I found that my antivirus software, Norton 360 blocks the network. with Norton, my Mac couldn’t access the network, so no backup nor internet. I had to disable then delete. As far as I know, this isn’t resolved.
Norton’s response was that they don’t support beta versions on Apple operating systems. They can’t explain why my wife’s Mac also has the same issue. Its on going...
