Disaster Recovery (DR) Solution
Today’s businesses are multinational, with operations that run 24×7, 365 days a year with little planned downtime. Applications vary from highly mission-critical to critical to non-critical, and each needs to be treated differently in terms of RTO(Recovery Time Objective) and RPO(Recovery Point Objective). Organizations like banks and eCommerce websites always need to be online with no data loss in case of a disaster. Complex dependencies are defined for applications that need to be considered when bringing applications back online following a disaster. A DR solution must take these complexities in mind and be easy to use with minimum manual intervention. Investment in such solutions is worth it because downtime comes with a heavy price tag that most reputable organizations can ill afford to pay.
Today, we are talking about natural disasters, which are still very prevalent, especially given the current situation with global warming, and manufactured disasters and outages because of human error, malicious insider attack, or a hacking incident by an outsider. A simple misconfiguration can lead to an outage that seriously undermines customer confidence in your brand. It is never a matter of “if I have an outage, what will I do” but rather “when I have an outage, what are the steps I will take to bring back services in the shortest possible time and with no data loss.”
What does a good Disaster Recovery solution offer?
A good Disaster Recovery Solution will offer the ability to replicate your data to a secondary site continuously and a never-ending stream of recovery checkpoints from which you may restore anything from individual files to entire datacenters.
Continuous protection with always-on replication ensures that any changes to your applications are protected as they happen. Unlike the snapshot method, continuous protection is comparable to a video recording that constantly records changes in your environment, and you can rewind the recording to any point and make that the new starting point. A good DR solution will also offer data encryption as it travels over a Wide Areas Network for security. Some solutions also provide bandwidth optimization replicating the initial copy of everything at the Primary Site to the DR site and subsequently only replicating the changes that can be made into a mirror copy of the primary site by applying to the DR site.
Data is synchronized across your Windows and Linux computers and a second real or virtual machine you provide locally, remotely, or in the cloud. Once synchronized, byte-level changes are continuously copied from your production system to the replica system, ensuring that data and information are accurate and systems are up and running.
- There is no negative impact on the production environment.
- There is no need to schedule anything.
- Data loss to a minimum level
- Because no snapshots are created, there are storage savings.
Failover testing can be a time-consuming process requiring the collaboration of multiple IT teams outside of regular business hours, even on weekends. To make matters worse, many have recovery plans in place that rely on the knowledge of certain specialists who may not be available when calamity strikes. With automated disaster relief testing, any team member can simply test ahead of time in an isolated bubble network, giving you confidence that your migration will be smooth and successful.
A distinct set of network settings and profiles is created, allowing you to control access and run tests without having to stop or disrupt the production application. Because testing takes place in its sandbox, it does not affect replication or protection status. All of this means you can test whenever convenient for you, giving you back your freedom of choice.
You can run a failover simulation for the entire data center or a single application. This is a great compliment to the background of the test, non-disruptive nature since it allows for easy scheduling and collaboration between infrastructure and application teams.
Pre- and post-replication scripts can be used to automate the recovery process further, and PowerShell and REST APIs can tailor the experience. Customer replication scripts can also be used to customize the testing process and automate other necessary configuration procedures in their environment.
Administrators can fail over users to the secondary server manually or automatically in minutes or seconds if there is an outage. The system can be reversed to an earlier point, before an error or infection happens, or reverted to a present moment.
The solution can be installed in the servers that are to be protected. Contact us to learn how you can implement a One-Click DR solution to protect your critical servers and applications
