POST 1
Hi All,
Disaster Recovery Plan (DRP) describes how an organization will resume after the occurrence of an unplanned event that can occur either by natural disaster or done intentionally by a human. It is an essential part of business continuity (to resume the business operations as quickly and effectively as before).
After watching the video, I would like to discuss few concepts related to DRP:
Cloud for Disaster Recovery: Cloud disaster recovery plan is one that uses public cloud such as AWS, Azure, or Google Cloud Platform to back up data, software, and other tools. When any kind of event occurs, those services can be transferred back to their original locations from the cloud whether those locations be on-site networks or the cloud. The cloud backup plans offer several advantages which include that the important data can be kept out of the office premises, there is no need for the use of backup tapes and other hard drives for data backup. These cloud methods are cost-effective, scalable, easy to implement. So, instead of using traditional hard drives for backing up the data, it is recommended to use the cloud for backup and recovery plans. Cloud disaster recovery offers more speed than conventional solutions and is more effective.
Traditional Approaches: In Traditional Approaches there are cold site, local hot site, hot site and Frugal warm sites are the common disaster recovery approaches. Local Hot Site, Cold Site, and Frugal Warm Site are the diverse congruity strategies most fitting to serve the business coherence just in the event of a disaster. Local hot Sites gives the full office to proceed with the business and give an arranged PC office, correspondence connections and offices for physical tasks. Frugal warm Site gives benefits that are like the Hot Site although it comes up short on the PC application and software. The principle advantage is that it has less cost than Hot Sites. The Cold Site gives the essential administrations and accordingly it requires long investment to get business continued it is more affordable. The Hot site is expensive and as the redundancy level is expensive and organizations must consider the cost/benefit analysis (CBA) of the usage of hot sites.
Blue lock Systems for Disaster Recovery: Blue lock systems provide highly effective disaster recovery strategies to speed up recovery during disaster. Such systems have an infrastructure managed by the internet (infrastructure as a service). This gives companies a pay-by-go approach to data storage and backup rather than making their own physical data centers. This also manages the traffic load between the two web sites of an company and the other site manages the entire traffic that continues the business transaction offered to the customers, if service failures occur. When an company manages confidential data, safety for businesses who use the cloud for their data recovery is a major concern.

Hello Everyone,
The speaker in the video, Pat ODay has explained about the modern approaches to the disaster recovery by using tools such as continuous data protection and cloud recovery. A disaster recovery plan is a process prepared by an organization to prevent the damage caused by the disasters and without effecting the normal business operations. The disaster could be a natural disaster, man-made error ore a power outage and in case of any such event organizations should be able to mitigate the risk and effectively recover from the impact. Three concepts which I learned from the video are as follows:
Key factors causing the IT disasters: The cause of a disaster in IT could be a server failure, human error, fire/flood or due to power and communication failure. As per survey, the major factor is the human error resulting from an intentional malicious attack that could corrupt an application, or if a patch update resulted in failure. The percentage contributed by human error is 47%, server error is 29%, power outage is 15% and natural disaster is at 9%.
Different traditional approaches for disaster recovery:
Cold site approach Data is backed up infrequently onto a tape or a cold site where all data from primary location is transferred to a cold site for every 24 hours. This is a very inexpensive type of disaster recovery since data is stored in tapes and bringing back the application from those tapes is a difficult task. So it consumes a lot of time to bring business operations to normal after the disaster.
Frugal warm site There is a primary location and a recovery location instead of tapes. Equipment placed in the recovery site might not be an exact replica of primary location, as a result of which it may not be able to resume all the services as the production environment. Data recovery after a disaster might take days to weeks to bring the business operations to normal.
Local hot site The local hot site is the exact replica of enterprise data center. If there is a disaster, then all of the enterprises operations can be moved to local hot site as it has equipment need to continue operation. However, the drawback with this approach is if there is disaster locally at both the places then data in both the data centers is impacted.
Hot site The replica of the primary data center is stored far away where the hot site is equipped with office computer equipment, telephone jacks, space and furniture. So, in an event of disaster all of the enterprises operations can be carried out from hot site without any major disruptions.
Modern approaches for disaster recovery:
Continuous data replication and backups All the application data is continuously replicated between the primary location and backup location using SQL injection. The failover is automated as a result, the application can be recovered within a minute. The automatic backups are used to replicate all the data from the primary location to off-site, so that in an event of any disaster entire system can be restored quickly. This helps in running the business with any major interruptions and with less downtime. This approach is effective due to its reliability, reduced risk and enterprise can focus on major business operations.
Cloud for disaster recovery (Recovery as a Service) Cloud recovery helps business to bounce back to normal business operation instantly by replicating entire system online. It lowers the cost for the system failure by minimizing the time required to move workloads back online. In contrast to traditional approaches, cloud-based disaster recovery is simple to manage and to set up. Using cloud, businesses no longer waste time in transferring backup data from their tape drives or recovery location (data servers) to recover after a disaster. All of these processes are automated in cloud by assuring fast and error-free data recovery.
