Then I copied over the 3.28.2 files to the folder I pulled off the Pi-3, then put that back on my Pi-3. Reboot and MX is back up and running at 3.28.2 but I am missing all the historical data when I view the MX dashboard. When I browse the Backup and Data folders on the Pi-3, the older .ini and .txt files still seem to be intact. I did see some FTP errors that seem to indicate MX was maybe NOT fully shut down?
Here is a sample when trying to FTP from my desk top back to the Pi-3
Command: put "C:\Users\frank\Desktop\pi3 Cumulus-back-up\CumulusMX\backup\daily\20240131000000\month.ini" "month.ini"
Error: /opt/CumulusMX/backup/daily/20240131000000/month.ini: open for write: permission denied
Error: File transfer failed
Not panicking yet but any advice would be most welcome.... That pi-3 / MX has been running perfectly for years.
Thank you!!
