What a data loss disaster is

A data loss disaster is a situation in which service from one physical site (for example, a building or a corporate campus) on the network is lost for an extended period of time.

The following are examples of disasters:

When a disaster occurs, it can affect all the computing infrastructure including storage systems, application servers, networking connectivity, and client connectivity. When you create a disaster plan, take into consideration all of your computing infrastructure.

• How to determine a disaster
  It is critical that you follow some predefined procedure to confirm that a disaster really has occurred.
• What tools to use to protect against data loss disasters
  Data ONTAP provides features and products for enabling the administrator to back up or replicate data stored on a local storage system to an off-site network location. This ensures data can be restored if data loss is caused by disaster at a primary data storage site.
