I tried to use your fantastic procedure for backing up openhabian on RPI 3B, it worked very nice. Now I changed to RPI 4 (4GB) with a complete SSD boot (no SD card used anymore). But here the script does not work, it looks like that USB stick will not be mounted to the SSD of the RPI 4.
After changing the fstab and exit the superuser, I typed in (after sudo su):
[23:58:50] root@openhab:/home/openhabian# mount -a
FUSE exfat 1.3.0
WARN: volume was not unmounted cleanly.
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the ‘nonempty’ mount option
[23:59:02] root@openhab:/home/openhabian# df -k /mnt/OHBackupDrive
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 115162364 3656472 106753556 4% /
[23:59:25] root@openhab:/home/openhabian# exit
exit
[00:00:01] openhabian@openhab:~$ sudo cp /mnt/OHBackupDrive/OHBackup_script /bin
cp: cannot stat ‘/mnt/OHBackupDrive/OHBackup_script’: No such file or directory
Although the OHBackupScript is on the USB Stick!!! What is going wrong on my side or is it the setup with RPI 4 and only SSD?
Thanks in advance for your support.
