Thanks for your answer! The documentation tells that if Apache is not running as backuppc user, the CGI file has to be run as setuid to the BackupPC user ( https://backuppc.github.io/backuppc/BackupPC.html#Step-9:-CGI-interface - standard mode).
And this is the mode used by BackupPC 3 when installed with APT packages on Debian. This is exactly what I did, but it is not working.. Il giorno lun 17 feb 2020 alle ore 01:05 G.W.
