Thanks for the explain, but...
- why in my tests, _whitout_ common direcotory, master and slave keep in
sync also if I shutdown slave, add (in my last tests) something about
100k record (although little ones) on the master and then after woke up
the slave in about 2/3 seconds I have all the dbs in sync? It's just
luck or there are something that I don't understand?
- If I have to copy (scp / rsync / etc...) the files, which interval I
have to follow? And also, when the slave will read these files? There
are something like inotify or I have to say to slave "my friend, there
are updates from master. Keep in sync!"

If I read before this page, I spared a lot of tries!
