Azure Site Recovery: Disaster Recovery on the Cloud

Disaster recovery is the process, policies, and procedures related to preparing for and recovering from disasters or emergencies. It involves having a plan in place to ensure that an organization can quickly get its critical functions up and running after a disaster or emergency.

Disaster recovery is important because disasters and emergencies can disrupt an organization’s operations, leading to lost productivity, lost revenue, and even damage to the organization’s reputation. By having a disaster recovery plan in place, an organization can minimize the disruption caused by a disaster or emergency and get back to business as usual as quickly as possible. Some common types of disasters and emergencies that might require disaster recovery planning include natural disasters such as earthquakes, hurricanes, and floods; cyber-attacks; and human-caused disasters such as fires and power outages.
