The way we keep the data up with low downtime is by using mirrored high quality disk systems. We monitor the servers 24*7 and if we need to reboot or otherwise service a server we off load the volumes to a spare machine before we do anything. In the end there is always the possibility that catastrophe can strike but all you can do is keep good backups and follow best practices when dealing with your servers. /sd
