Disaster Recovery Planning
When business is running the way it should then it's easy to forget that things can go wrong. Critical IT hardware should be configured in such a way as to ensure that when hardware fails (and it will fail at some point) then business can continue with little or no interruption. This least reliable parts of a Server are the hard disks and the power supply. A correctly specified Server will continue operation even through a hard disk or power supply failure. If this isn't possible with the current set up then backups can be taken via cloud, still giving access to business critical data.
The correct DR (Disaster Recovery) Plan can ensure business continues even though hardware has failed.
