Something about restoring your server

1. What the restoring are you talking about?
A computer system is considered to be fault-tolerant not because you make backup copies. Fault-tolerant is the system which can be restored after the crash. No any backup procedure makes sence until you are able to restore data from a backup. The truth is that most of systems administrators have never tried to restore their servers from a backup, and this is just a matter of fact, mostly not depending neither on a company size nor on IT staff members count. This task usually is moved to the later/better time, re-assigned to other team members (so-called ”football game”) or is performed partially (”let’s try to restore the database only and consider everything to be o.k. if it is restored”).
But the thing is that failures do not warn you in advance.They are not gonna call you stating ”get ready, this will happen in a week” neither send you an e-mail message. So what problems do unexperienced in restoring servers administrators face when critical failure occurs? (Frankly, not only servers, but mission-critical workstations as well.)
