I have created a home network consisting of mostly Ubuntu 10.04 PCs and
a Windows PC (XP). One of my Ubunto systems has large USB attached disks.

I am trying to make that system a "backup" server. I started by
installing rsync on a couple of the Ubuntu systems, but have not been
able to get it to work, in spite of paying close attention to the
information I can find on the Net.

I am open to the idea of using a different package, but would like to
know that there is sufficient DETAILED information to let me implement
it (I am not a newbie to Linux, but I am not exactly an advanced user,
either).

What recommendation would any of you like to make and where can I find
detailed implementation descriptions?
