Hi,
I am new to Duplicati so please be a little patient.
I tried setting up Duplicati so it uses a SSH connection to my Ubuntu server. When I hit “test connection” it says connected successfully", however, when I run a Backup job this fails. The logfile says this:
Have you tried a file upload with a different SFTP client such as WinSCP, Cyberduck, Linux sftp, etc.?
You should use whatever login credentials you’re using with Duplicati. Perhaps that login only allows a directory listing (which is what a Test does – it’s just basic connectivity), but denies ability to write files.
The failed operation can be seen in more detail with About → Show log → Live → Retry during backup.
