My backup server is actually my dev machine.
My backup server is just a reporting machine.
My backup machine is using SATA just because it is just an absolute
emergency machine.
My backups machine is also my web server.
Real world dictates differently. Let's not forget that not every company
can spend 100k on two identical machines, yet many companies can spend
50k + 5k for a backup machine based on Sata or secondary services.
Sincerely,
Joshua D. Drake
