systematic backups in Linux?

[Karen Lewellen]

Hi there,
Thanks once again for the command and ideas.
Frankly I do not want anon line option.  If that were safe enough I 
would just leave things here at shellworld.
I think my biggest worry is maintaining  the speed and normalcy with which 
I work.
I realize many here spend their lives working with and playing with this 
technology, but I run a production company, so want a Linux setup that is 
solid reliable, and need not be changed every other week.
You have totally persuaded me that ftp is not the way to go.  I love the 
idea of flexibility and updated backups.
Now to get the rest of what I need together.
Karen
