It takes you 4 hours to setup a web server?! Wow. You know, there are ghosting and imaging technologies that you can use to have a pristine "golden image" restored in under 3 minutes, right? Depending on your network and data restoration techniques, you should be able to restore data back on the drive as fast as the drive can go. Assuming this is a data center with raided FC or SCSI drives (you should be able to afford that if a single server is responsible for $500/hour of revenue), there should be no reason why you can't achieve 300 MBps during the restore- 800 MBps if using a moderate SAN. My experience has shown that when a box goes down, and I need to rebuild, if I'm at it for more than 20 minutes, I'm wasting time. > and if you use something from your > previous install that has something you don't want, you've gained > nothing. if you go and reinstall the backend db, you might have gained > nothing as if you recreate the db with your old data that has an account > you don't want or a trigger that does something you were trying to stop, > you gained nothing. Garbage. That's the whole point of restoring data. If you are rebuilding a server that just got compromised, you restore everything the server contained up to break in. > remember, there is rarely a good reason to reboot a linux box and even > less of a reason to reinstall. More garbage. There are _many_ good reasons to reboot a UNIX or GNU/Linux server: * Proper maintenance ensuring all services start on boot. * Cleaning out stale memory and swap as a "refresh". * Booting into a new kernel. * Forcing applications to use the new libraries. * Ensuring all hardware is still in good, working order. * Running filesystem checks on filesystems to make sure data is sound. * Even modifying partitions or filesystems to accommodate new storage needs. > imo, good logs, properly configured ids, services run in chroot, > selinux, and properly configured f5 are better than wasting time for no > good reason. Anything is better than wasting your time. What's your point? -- . o . o . o . . o o . . . o . . . o . o o o . o . o o . . o o o o . o . . o o o o . o o o
