Here are some of the options of file transfer:
Option 1: (Recommended for local LAN)
Whenever you connect an external USB hard disk to TonidoPlug, it automatically makes the contents of the disk available as a network drive. You can access this shared network drive from any other computer within the same local network. Now that the USB disk is available as a network drive, you can copy all your files to the USB hard disk as if you are copying from one folder to another on the same machine. For more information, see TonidoPlug: Access as a Drive.
You can login into Tonido's Web interface and browse to the location of your USB disk (e.g. /media/disk1part11) and then use the built-in upload functionality to upload files into any desired location with your USB disk. This procedure is same whether you want to upload files from another machine on the same network or from a remote location. For more information, see Upload Files via Web.
You can use the ' Mount as Local Drive ' functionality offered by your TonidoPlug to access the external USB disk from a another computer. This option will work whether you are in the same network or in a remote location. However it is not recommended to use this in the local LAN, because option 1 is fast and robust for same network file transfers. For more information, see Access as a Local Drive
Option 4: (Advanced)
Since TonidoPlug runs Ubuntu Linux as the operation system, the OS capability can also be leveraged for file transfers. You can use the SFTP protocol (using tools like FileZilla) to copy files to/from TonidoPlug. This option can be used in local LAN and is recommended for only advanced users familiar with Linux OS.
1. Some older version of the plugs will have the USB disk available at /media/usb0
