Which protocol should I use for communication to central server?

[Patapon]

sftp or ftp or bzr, which one is the most reliable choice? I have tried
Guildftp (A free and stable ftp server), and fails at
bzr init-repo ftp://anonymous@localhost/proj

D:\temp\proj>bzr init-repo ftp://anonymous@localhost/proj
> bzr: ERROR: ftplib.error_proto:
