backup on network disk

[roland]

Hello,
I am using ncftpput to make a backup on a network disk like 'LaCie'
and it works
tar -cvzf - /home | ncftpput -uroland -p mypasswd -c 150.50.50.4  
backup/home.gz

I tried the same on a 'conceptronic'  disk and I received the message as  
you can see in the annex.

Is there anybody who has an idea what this could mean?

Thanks for your help,
