For a one-off budget server in 2002-2003? Yes, yes it is. For a highly-available mission-critical infrastructure in 2013, the failure plan is also to rebuild from scratch, because "failure" means redundant and backup systems have exploded. This is most likely to occur when you automatically roll out untested changes to your infrastructure. In either case, you won't be sleeping tonight. Or possibly tomorrow night.
