Data Safety Push Business practices and regulations have evolved in such a way that it is now necessary not only to have geographically dispersed copies of data but also to have nonrewritable and nonerasable media to protect it. Here are examples of regulations that suggest or require better data retention and protection.
The SECs Rule 240.17 a-4(f) calls for organizations to store business documents for no less than three years while keeping data in an accessible place for two years.
HIPAA has a number of guidelines for document retention and security. Although WORM is not specifically named, it is very often the best choice for preserving the integrity of data for several years.
Why data replication over WANs?
The "Draft Interagency White Paper on Sound Practices to Strengthen the Resilience of the U.S. Financial System" suggests, but does not require, that organizations have a 200- to 300-mile separation between primary sites and backup sites.
HIPAA calls for IT managers to make sure that, in the event of a disaster, data is protected and that the backup site can become operational in a short amount of time.
