What I need is this:
1) choose some directories on one disk and have these directories mirrored on another disk automatically. For example: suppose I have a directory on diskA called /myFiles and the same directory on diskB. Now, every time I change something on diskA, the changes are echoed to diskB automatically. If I delete a file on diskA, the file is deleted from diskB and so one. A mirror.
Is there a way to have some deamon, service or whatever running on background that allows me to do that on Mac OS X Snow Leopard?
NOTE: I know about Time Machine and about rsync and other manual synchronization tools, but what I need is just some directories on one disk to another.
