Backup through FTP fails – “error getting SYSTYPE”

Hello. I have set up an FTP server using vsFTPd. It is accessible and perfectly usable with Filezilla.
BackWPup seems unable to use it, though, as this bit from the log reveals:

[28-Nov-2022 15:56:28] 1. Try to send backup file to an FTP server …
[28-Nov-2022 15:56:28] Connected to FTP server: 12.34.56.78
[28-Nov-2022 15:56:28] FTP client command: USER user
[28-Nov-2022 15:56:28] FTP server reply:
[28-Nov-2022 15:56:28] FTP client command: PASS *******
[28-Nov-2022 15:56:28] FTP server reply:
[28-Nov-2022 15:56:28] FTP client command: SYST
[28-Nov-2022 15:56:28] ERROR: FTP server reply: Error getting SYSTYPE
[28-Nov-2022 15:56:28] ERROR: FTP Folder "folder" cannot be created! Parent directory may be not writable.

The folder in question exists in fact and I even used “chmod 776” in order to ensure it is writable by anyone and exclude issues with the permissions. Given the above, the issue seems to lie with BackWPup: what can I do to make it work?

I am using WordPress 6.1.1 and BackWPup 4.0.0.

Thank you.
