I have Start9 running fine on a RPI 4 9GB but recently had the SD card fail. I re-installed from the Github download and restored the server fine.
Deciding I needed a backup I setup the path to an other local Pi and this looks fine. I get a permisson error. Does this need root user privilege on the backup device, maybe somebody recognises the error here?
This almost always means that something is not quite right in the config you entered. Double check the steps in the guide to be sure you got it exactly right.
I am revisiting this old thread to report how the issues I described were solved. In the meantime I have had a couple of SD card fails on my server which is a Raspberry Pi4 B in an Argon One case with an M.2 SATA SSD
First step was to carefully go over all the SAMBA instructions per Start9 documentation.
After this it was a logical process of reading and understanding all the linux errors to methodically resolve.
The path to the backup directory was all good as was my username and all passwords, both master password on Start9 and a second RPi on my wired network that does little but has a large SSD.
The main issue came from permissons on the target directory at the end of the ‘path’ as defined in the samba.conf file . Here is what I did wrong!!!
sudo mkdir -p /home/$USER/start9-backup which is not what is instructed in the documentation. Pure muscle memory put that ‘sudo’ in there which meant whatever way I wrangled with the name or IP address of the target machine and whatever combination of username and password I tried I did not have permission to write to the backup directory. Staring at my own mistake for how long!!!
Anyway, sudo rm -r was enough to remove the old directory belonging to ‘root’ and re-created the directory as my default user meaning I had correct permission to write to the target directory on the backup machine.
I am still learning the hard way but happy to now have a backup of my server to restore from if I have any more hw failures. Hopefully my woes may save somebody time and fingernails!
