What one organization considers a disaster might be much different than what another business might see as disastrous. Perhaps one sees the loss of a few hours and a few files as something that can be recovered, while another sees every lost moment and each iota of data as a catastrophe. Whichever camp you find yourself in, you need to be able to do two things: first, gauge how serious a given data loss disaster is, and secondly, establish what must be done to get back in action following said disaster.
