Fileserver: Samba or NFS or ?

[rtjohan at syspres.com]

Hi all,

For backing up WinXP machines to a FreeBSD 5.1 fileserver, what are the 
pros and cons of going with Samba vs NFS? The fileserver is being 
updated regularly using cvsup/portupgrade -ra. BTW - is a make world 
ever necessary for security patches.

Especially concerned regarding security.
Can either one be locked done well?

Seems like both have had security problems in the past. Are these issues 
resolved at this point? Is there maybe a better alternative?

Especially interested in if Samba or NFS can be paired with some 
encryption transport protocol.

Thanks for any advice,
Richard
