I viewed his phrase < program to automatically mirror > as something other than Norton Ghost or DriveCopy. RAID 1 is automatic mirroring to another drive, albeit more than just a directory. In any event Windows 2000 and XP have some built-in mirroring function I am told. At $99 for another 40GB HD and maybe a few more bucks for another hard drive controller, hardware failure loss would be minimized cheaply. Physical loss from a fire is something else. The elegant solution IMHO, a service that calls your computer and downloads all changes to its own computer storage which is offsite of course. Some small law firms do this.

RAID will dynamically replicate data from one disk to another. It will, in some forms (check the raid level), protect you from a single disk failure in that the 'slave' copy will stay true. However it will not protect you from data corruption of a database. If a wrinkle gets into those bits (be it fat-finger or data corruption) on the 'master' then that corruption will be faithfully be reproduced in the 'slave'. Keep doing those backups folks! Perhaps the original requestor was looking for some means of doing a periodic trigger of a copy from 'primary' to 'secondary' disk? This way one can validate the database, then trigger the replication. Even then - keep doing those backups. Disaster planning is a business of it's own. People that do this for a living think of the data backups, data storage, how the data gets from there to here and back again when needed, fire, equipment failure, transport vehicle accident, earthquakes, tidal waves, terrorists, thieves, and even weapons of mass destruction. As someone once said - Keep doing those backups - AND get them 'off site'. \s\Rick -------------------------------------------------WRT------------------------ --------------------- > Try searching for various RAID functions. > search <google> using <raid drive mirror> or merely <raid> > ... -------------------------------------------------WRT------------------------ -------------- > Does anyone know of a program to automatically mirror a directory to another > hard drive? > >... ==== FAMILY-ORIGINS-USERS Mailing List ==== GETTING THE MOST OUT OF FAMILY ORIGINS by Bruce Buzbee - FO DEMO http://formalsoft.com NO WEB ACCESS?
