It’s possible the memory stick is formatted in a way the Nucleus can’t read - it can’t read the native Mac formats
If your music is stored on an external USB drive, plug it into your Nucleus now. Nucleus supports USB drives pre-formatted as EXT2/3/4, VFAT/FAT32/FAT16/exFAT, NTFS, or HFS/HFS+. Note that HFS/HFS+ (also known as “Mac OS Journaled”) is read-only, which means that the Nucleus will not be able to make changes or store new music on the USB drive.
Thanks Guys. That’s correct. I successfully backed up to the memory stick but the nucleus would not “see” the memory stick.
But, being impatient by nature and not familiar with how it all works, I overcame the problem by ignoring a backup and starting a fresh core on the nucleus. I’ve lost my playlists but I had very few and don’t generally use them. My music streamed from Qobuz has successfully shown up on the nucleus and I’ve added the music I have as downloads.
So all working fine now but there should be a helpline direct to Roon to help people set up and other problems.
I’m not familiar with Apple computers, but in Windows I start from the other end. Go into your computer and set up the folder and determine the path to your Nucleus, etc. Then input that on the Nucleus to set up your automated backups.
In the end I decided to backup to Dropbox which was an option that was there already. Seems to be working well but why Roon can’t have a better explanation in their instructions and a helpline, I don’t know. It’s a good system but not too customer service.
