Usage on Linux

To connect to the Dedibackup service, we recommend lftp for interactive use and curl for automated tasks:

Recommended tools

• For interactive connections: Use lftp, which offers an interface and flexibility suitable for FTP sessions.
• For automated scripts: Use curl for automation, though some limitations exist with FTP servers that do not support all commands.

Example of interactive connection with lftp

For interactive sessions, use lftp with the following command:

apt install lftp  # Requirement
FTP_HOST="ftp://dedibackup-dc3.online.net"
FTP_USER="sd-XXXXX"  # Replace with your server ID or 'auto' for autologin
FTP_PASS="your_password"  # Leave blank if using autologin
# - Connect to FTP server
# - Upload a file, list files, remove a file
# - Disconnect from FTP server
lftp -u "$FTP_USER,$FTP_PASS" "$FTP_HOST" <<EOF
# Change to the specified FTP directory
cd "/"
# Upload a file
put "path_to_your_file.7z"
# List files in the folder
ls
# Remove a file
rm "file_to_remove.7z"
bye
EOF

Example of automated connection with curl

When automating tasks, you can use curl, though command limitations may apply:

# Upload a file
curl -T "path_to_your_file.7z" -u "sd-XXXXX:your_password" ftp://dedibackup-dc3.online.net/
