Begin here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/disks-virtual.html By what process will files change? A requirement such as this implies something more than generic filesystem actions, an application such as an accounting system. In that case, the slave feature of mySQL may be what you need, and check out postgresql, too. If the database solution doesn't fit, perhaps the application could manage the redundant saves or periodic syncronization. Gary Dunn Honolulu
