All backup process are ok until step "Upload to remote FTP".
"..Uploading <root>/backups/site-xxxxxxxxxx.com-20190214-211128+07.sql has failed. \n Failed to process file"
When i set it in akeeba, i test my server and have "(green) Connection to remote FTP server was established successfully!"
I precise that I have tested my FTP server with client FTP Filezilla and all fine = i can list, download, upload.
.. An idea maybe ?
