ftp

I have some basic issues with backups and ftp.

On trying to back up one of my sites, I get ‘PHP process is unable to write files to your server. Please configure FTP access to continue.’ SO I click on it and it asks for ftp username/password – I don’t know what it’s asking for? And what’s the ftp path?

Also I have two successful backups but the size is showing as 0MB. That doesn’t seem right?
