SAN Recovery - Disaster recovery
Disaster recovery involves a series of policies and procedures intended to help the recovery or continuation of a technological process after it had been affected by a natural or man-made disaster. IT disaster recovery is all about planning for resumption of applications, data, hardware, communications and related infrastructure.
Typically, large organizations spend about 2-4 percent of their IT budget on disaster recovery planning. This would help them avoid major business loss in the event of a disaster. In the past, very few instances were reported wherein a company survived after it had suffered a major loss of business data.
Types of disasters
Natural calamities like earthquake, hurricane, flood and fire can lead to major data loss. However, the impact of this can be reduced by taking precautionary measures such as replication of data, implementation of high-availability systems, and effective disaster management policies.
Man-made disasters are major concerns for IT organizations. Human intervention - intentional or unintentional – can cause massive damage to IT resources. Examples of such instances are sabotage, burglary, virus, intrusion, and the like.
Security holes are one of the main causes of man-made disasters in an IT system. Security holes arise due to vulnerabilities in computing hardware or software. Such systems are prone to hackers and other malicious attacks. The result of these attacks can be disastrous to the organization.
By adopting precautionary measures and implementing effective anti-virus software, organizations can ensure safety to their IT infrastructure. Most important precautionary measures include use of disk protection technologies such as RAID, surge protectors, and provision for uninterrupted power supply.
