It all started in the data center. Once computers became part of the business landscape, even before the introduction of personal computers on individual desks, it became pretty clear we could not return to our manual processes if our computers failed. The business model changed. The work people did with manual general ledgers in ledger books or with their hands in a manufacturing environment were now done more consistently, with fewer errors and many times faster by computers and if those computer systems failed, there were not enough people nor did the people in the business still have the skill to do it manually anymore. The disaster recovery industry was born! Still today, the term “disaster recovery” (DR) commonly means recovery of the technology environment.
