I go further than that. A true backup cannot be manipulated while the primary copy is online. Say, for example, you have two sites, and replicate data from one site's server to the other, and vice versa. All set, right? Well, what happens if you have a rogue employee get system access and nuke everything in *both* locations at once? Or how about malware that manages to get in, and does the same? Or maybe just a software bug that corrupts everything (maybe you've got the same model and firmware on both SANs)? I always want some copies on offline media, locked up, somewhere else. I want time-consuming, manual, physical action to be required to get at them. They don't have to be updated every day, perhaps, but they should exist. This can be as simple as a removable hard disk locked in a fire-proof safe, located at the home of a trusted employee who lives in another town. Or in a safe deposit box, in a bank branch in another town, if you prefer. That way a typo can't wipe out everything in seconds. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
