If you use `Commandline` in GUI (no need to actually run anything), is your folder in the box called `Commandline arguments`? I don’t use MSSQL, but don’t know what “I have selcted my sql” says.

As @ts678 suggested, this means that no sources are added for backup, despite you checking the server. An alternative to the “Commandline” way is to use the text input:

From here we can see if the sql server is indeed being picked up.

Also if you have any additional settings (specifically, disabling modules) this can also impact the results.

Same problem. The databases are selected, but it says “No source folders specified for backup.”

Windows Server 2022, Microsoft SQL Server 2022.  
Previously worked on Windows Server 2014 and Microsoft SQL Server 2014.
