Just bought a new Nucleus Plus for a 2nd home. I backed up my library on an SD card formatted in ExFat, and inserted a SD card reader in a USB port on the Nucleus. The Nucleus has the latest software. But as you can see from the following screenshots I can’t get it to recognize by backup.
Yes, I’ve copied my original Backup file from my SD card onto my MacBook Pro, and confirmed the Backup file contains 9.5GB of data and over 45K items I transferred the Backup file onto an external solid state drive, and get the same results. Lastly I used my PC as Roon core and tried Backing up with the same results.
I’ve successfully used this procedure in the past. And it’s not practical for me to perform another backup of the Nucleus at my 1st home.
Thanks for confirming you are able to locate that file, this is strange behavior in that case. Do you by any chance have a PC around the house and can install Roon on it and set it as the Core? If you try to restore this backup to a PC Core, does that work as expected?
Fortunately I had used my MacBook Pro as a Roon core about 9 months ago. So I was able to salvage the database from that core and install it on my new Nucleus. About 90% of my 2,000 album library looks ok. The other 10% will take a while to reconstruct the meta data. Interestingly a number of albums have tracks spread across 2 or more different entries in Roon, so I have to use the edit feature to merge them back together. Even though each album is in separate folders with identifying titles and album art.
