Backup utility for Linux?

I'm looking for something that I can use to backup data to a NAS, something like this would be typical:

Source: //mail/scalix/ all subdirectories excluding //mail/scalix/temp

Destination: //data1/Daily/scalix

I'm average to poor at batch files so wondered whether there's a non scripted solution (on Windows I use an application called PTReplicator from http://www.karenware.com) on Linux (RedHat).

If there's nothing like that around where can I find a good primer on scripting?

tar cvf /data1/Daily/scalix --exclude /mail/scalix/temp/* /mail/scalix/*

That simple? Muchas gracias

if /data1/Daily/scalix is the destination directory, then you really want this instead:

tar cvf /data1/Daily/scalix/bkp.tar --exclude /mail/scalix/temp/* /mail/scalix/*

Thanks, been busy will try next time I'm in the office.
