Have you ever heard about cloud disaster recovery? Maybe there are still many who do not understand this. Even for business people who use cloud technology, there are still those who don’t know about it. In fact, what is called disaster recovery is very important for your company, especially those that use cloud technology.

Why is it that so many don’t know about it? Because basically, almost 80% of companies in Indonesia do not have a DRC (Disaster Recovery Center). In fact, a business or company will depend on the primary data center, because various data and applications are stored in the data center.
Why need cloud disaster recovery? Is it really so important for company data? Let’s talk!

Getting to Know Cloud Disaster Recovery First
Cloud disaster recovery is not a new thing, but many companies don’t understand this. For example, various data is stored in the primary data center. However, when the primary data center experienced a breakdown? Even if it’s only for a few moments, of course, it will make a company or business lose money.
Therefore, companies need something called DRC for their cloud network needs which are primary storage.
What is Cloud Disaster Recovery?
Before that, let’s talk about cloud disaster recovery first. Cloud disaster recovery (cloud DR) is a combination of strategies and services intended to back up data, applications and other resources to a public cloud or a dedicated service provider.
When a disaster occurs, affected data, applications and other resources can be recovered to the local data center or cloud provider and resume normal operations for the company.
Benefits of Cloud Disaster Recovery
The goal of cloud DR is almost identical to that of traditional DR: to protect valuable business resources and ensure that those protected resources can be accessed and restored to resume normal business operations. DR is a central element of any business continuity strategy.
Prior to the advent of cloud connectivity and self-service technologies, traditional DR options were limited to local DR and second site implementations. Local DR does not always protect against disasters such as fires, floods and earthquakes. A second site off-site DR provides significantly better protection against physical disasters but incurs significant business costs to deploy and maintain a second data center.
How Cloud Disaster Recovery Works
In order to fully understand cloud disaster recovery, let’s talk about how it works.
Data Copying from Primary to Secondary Site
So, the way cloud disaster recovery works is to copy data from the primary site to the secondary site before the disaster occurs. Then, the secondary site will then take over and enable access to the data copy automatically while the primary site has problems.
However, this copying is no longer used after the advent of cloud technology. Companies will find it easier to quickly move data and access it, because storage is done virtually. You can even unlock them during certain disasters.
Data Retrieval to Secondary Site
So, what will happen when the unexpected disaster occurs? The information operational system for the primary site will be terminated, so that the copying of information to secondary information will also be interrupted. Then, granting access to the secondary site will also be disabled so that you can access the information that has been copied.
Then, when the primary site is down, the secondary site will be activated by operational processes for data retrieval. The primary site also usually performs recovery immediately while the secondary site is active, so that you can take advantage of it again once the disaster is resolved.
Rebuild or Repair on Primary Site
Then, when the disaster occurs and the secondary site becomes the primary storage, the primary site will rebuild or repair as a result of the disaster. In this case, those of you who have applied cloud disaster recovery will not have to wait too long and can optimize information on the secondary site.
Once the rebuilding process is complete, the new data that you have stored on the secondary site will be copied to the primary site, so that both will have the same version. As a result, you can use the information on the primary site without starting from scratch or repeating it.
Returning the Operational System to the Primary Site
After the rebuilding process has been completed, what to do next? The information operational system will be redirected to the primary site. But before moving, make sure that all work on the secondary site has been moved or is no longer being carried out. Then, stop the entire process of copying information from the secondary site to the primary site.
To expedite the process, use special hardware that can lift write-protection which is usually available in the primary site. Transfer operational information processes so that the use of the primary site as the main web is again effective as it was before the disaster occurred.
Implementation of Disaster Recovery for Business Interests
Do you know that cloud disaster recovery is very important from the way it works and also the understanding? Are you still hesitating to have it? Maybe if you own a business, this is a very important technology.
The application of disaster recovery in business is due to various reasons. However, to run it optimally, find out its application to your business as below:
Asset and Infrastructure Evaluation
Of course, assets and infrastructure are very important parts of your business. So, the very first thing you need to do is make a detailed list of assets and infrastructure, including the type and size of information stored, in anticipation of a disaster that could strike at any time.
The results of the report that you created earlier can later be used as a guide to determine the amount of investment, how to use it, to the costs of backup and restore incurred.
Define Disaster Risk Parameters
The next step is to determine the risk parameters that occur due to the disaster when it occurs. There are two aspects that you can consider, including the Recovery Time Objective and the Recovery Point Objective which are related to the duration of the stoppage of benefits and damage.
Designing a Disaster Recovery Plan
If you have determined the risk parameters that will occur when a disaster occurs, then it is your job to design a recovery plan if, for example, a disaster occurs.
What you can do, for example, is to provide backups or backups, businesses must and are legally obliged to design and duplicate data as a secondary knowledge system or warm standby. Replicating data storage areas can also be done as an emergency backup.
Test the Disaster Recovery Plan Periodically
After all of the above have you done? What’s next? Of course is to test it!
Plan disaster recovery testing by setting a schedule. Then, after receiving important information from the part, evaluate and replace the necessary details. Then involve including the employees involved in the recovery part so they are better prepared.
Use Trusted Cloud Provider Services
Well, one of the things that causes disasters to happen is one of the factors from the cloud provider. Cloud services that service providers present need to meet the standard requirements imposed by the authorities. Make sure they have a layered security system, fast data recovery, and storage capacity as needed. Antivirus and antimalware packages can also be considered.
