Hello.
First, sorry for the late to summarize.
Thanks to everybody for their answers. Here is the list :
Mark Bergman <bergman@phri.nyu.edu>
Alex Finkel <afinkel@pfn.com>
Raju <raju@pez.ecologic.net>
bismark@alta.jpl.nasa.gov (Bismark Espinoza)
Martin Espinoza <drink@sei.com>
There is no particular winner :-)

And the answers :
Martin Espinoza <drink@sei.com> :
In order to do this you would need to install a package 'NetATalk'
on a sun machine which will allow you to mount AppleTalk shares
on a SunOS4 or SunOS5 machine, or vice versa.
also you might be able to find an NFS package for Macintosh.
bismark@alta.jpl.nasa.gov (Bismark Espinoza) :
You would have to do this:
1. Make a tar file in UNIX
2. ftp to Mac with a HERE script
% ftp remote_comuter <<EOF
username
password
put tarfile tarfile
EOF
Or use the .netrc file to automate.
Raju <raju@pez.ecologic.net> :
You might want to look at 'cap60' it lets you use a unix box as a mac
fileserver, I played with it and it had a lot of problems. I use a
package called 'amanda' (ftp://ftp.cs.umd.edu/pub/amanda), it's pretty
easy to configure, does network backups (between unix machines) and
is fairly automated.
Alex Finkel <afinkel@pfn.com> :
I haven't tried this myself, but if you got a good NFS client for the Mac,
you could just export your filesystems (SunOS 4.x) or share them (Sol 2.x)
and then NFS mount them on the Mac. As long as the Mac had the right
permissions, it should be able to back up. Beware though that NFS can be a
security problem if you are backing up the entire filesystem including
password files and such. Also, if you have a busy network, performance may
be poor.
You might want to look into a commercial backup program if you have a lot of
data to protect.
Mark Bergman <bergman@phri.nyu.edu> :
=> I would want to know if it is possible to make a backup (like "dump") of
=> disks of a Sun (included system disk) via TCP/IP network to a Macintosh
=> hard drive ?
=>
I've never heard of anyhting that will go form Sun ==> Mac, but
there are a number of products: SM-Arch, Legato (Solaris Backup),
that do Mac==>Sun.
=> My first idea was to backup the files of the Sun on the Macintosh by FTP.
=> And if i need to restore the backup, i have just to install a FTP server on
=> the Macintosh and access to backup with a FTP client on the Sun. But there
=> is the problem of file permissions/users...
Worse still, if you need to do a complete restore (after a crash) of
the Sun, you'd need to do the restore by hand (from CD-Rom or tape),
install and configuring TCP/IP services, and install and configure FTP,
before you could restore the backed-up files.
=>
=> So, is this idea is realistic ? Does exist a freeware to do that (a sort of
=> "dump" via FTP) ?
You could take the source for dump (form the FreeBSD or Linux or
possibly 4BSD distributions) and try to port it...
Ouch.
