Elasticity, scalability, rapid provisioning, and cost effective resource use are just some of the benefits of cloud computing. However, for disaster recovery, the most important benefit is that it is cost-effective. A business organization need not implement its own comprehensive disaster recovery plan. A cloud service provider can offer multisite availability and fast recovery times at less than the cost of the traditional disaster recovery.
A disaster recovery through virtualization in the clouds provides faster recovery times because a server is not dependent on its hardware. The server’s data, applications, patches, and operating system can be accurately and safely transferred between datacenters without the need to reload each of the server’s components. Because recovery times have become faster with cloud computing, it is also become more cost-effective. In fact, recovery can take a couple of minutes only. There is also no need for tape backups anymore because backups are already done online.
If you’re thinking of moving your disaster recovery to the clouds, it is important to consider using various Internet Service providers in order to prevent any failures. Most business organizations today utilize network hub technology which connects to different Internet Service Providers for failover and traffic load balancing. In fact, implementing the use of various online channels must be a part of any disaster recovery plan.
Desktop software must always be on hand in case a disaster occurs on the virtual software. It can be inexpensive and easy to keep physical copies rather than keep everything in the clouds. Also, before signing a contract with a cloud service provider, it is important to test applications which are mission-critical. You shouldn’t rely on the guarantees of the cloud service supplier only. Some business organizations even practice a failover quarterly to ensure that the failover and disaster recovery are working.
Even for private clouds, virtualizations and new applications can offer quick replication of applications and operating systems for failover and disaster recovery. With this technology, deployment time is significantly reduced. If you have a large business with different branches in other locations, it is good practice to deploy a separate failover and disaster recovery plans for each of the locations so that when a catastrophe strikes in one area, it is easy to move to different sites in various locations.
In a study made by cloud storage provider TwinStrata, 75% of the study’s respondents claimed that they were able to recover data from the clouds with the day. However, 12.5% of the respondents admitted that they don’t use cloud storage and that it takes a week for them to recover their data using the traditional data recovery alternatives. In that same report, it was also found out that business organizations use the clouds primarily for data storage with medium-sized companies leading the pack of cloud storage adopters.
