Done a clean install of Catalina today, and am trying to get time machine running again. 

 

I remember a thread a while back about SMB, and the suggestion that fixed it for me was to re mount the time machine share and I could then see the share in time machine and use it to backup. 

 

Im back at that stage again, and I've mounted, un mounted a few times the share, there is a command to enable the os to backup to an 'unsupported' volume...

 

 defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

and ive entered that, but still can't see the mounted time machine share from unraid to be able to back up to it.. 

 

Anyone have it working? 

 

Thanks

Turn on Mac os x compatibility in the smb settings on UNRAID then for the share you are using set it to a time machine share. I backup to a smb share on Catalina. 

I have the SMB settings set, and my export is set to Time Machine on the share - I just can't get time machine on the Mac to see it. 

 

It was all working fine on 10.14 before I clean installed and has been great for the past 3 years - usually I do an in place upgrade but now and then I like to clean the machine, its been 4 years or so since I did a clean install. 

 

This time I wiped the machine and installed clean (I do every few years) so not sure if the clean install is causing anything

 

I may restore my disk image before I wiped the machine and do an in place upgrade just to see if it works ok then

 

 

removed the security from the Time Machine share and made it public, reconnected it to the Mac, and I can see it now in time machine, will mess about with security settings and see where I go.
