How Do I Recover Data From the Cloud?
Losing important data is most people’s worst nightmare. From intrusive viruses to damaged hardware, there are many different ways in which you can suddenly lose valuable information. On the bright side, the emergence of cloud computing has made things substantially better.
Cloud storage allows users to save files in a non-physical location and access them remotely from different devices. Losing your phone or your laptop isn’t the end of the world if you have all your important files saved in the cloud.
All that being said, cloud storage isn’t infallible. Yes, it is much safer than relying on a physical hard drive, but the possibility of human error is always there. When employees are rushing or unsure, the chances of making costly mistakes such as deleting or overwriting files multiply. To make things worse, cloud services can also be the target of cyber attacks that can compromise valuable data.
Even if you store all your data in the cloud, it is important to have a solid recovery mechanism in place. Keep reading to learn more about how to implement a cloud-based disaster recovery system.
Methods for recovering cloud data
Before cloud computing, IT disaster recovery involved the storage of backup data to different physical locations. Although this process was more straightforward than it seems, it was far from perfect. It involves too many manual processes, making it too time-consuming for the fast-paced digital environments in which we currently operate. Additionally, it was quite expensive, as companies needed to pay for the additional hardware and storage room.
Fortunately, cloud computing has made disaster recovery more cost-effective and accessible. In a nutshell, cloud data recovery is a more advanced version of traditional disaster recovery methods. In fact, the gist of it remains the same. Cloud data recovery still involves storing data in different locations so you can go back to how things were if something goes wrong.
So, what are the different methods of cloud-based disaster recovery?
1. Warm standby
Also known as hot spare, this is a method of redundancy where a backup system runs in the background of a primary system. With warm standby, there is a scaled down copy of your data in a different region. The main benefit of this approach is that it’s perfect for performing disaster recovery tests. On top of that, the scaled down backup can be accessed immediately at any point, significantly reducing downtime.
However, there are a couple of drawbacks. The first one is that warm standby doesn’t completely protect you from data loss. Its main function is to minimise downtime, which is why it’s always running in the background. And that ties directly into its second disadvantage. Because it requires plenty of resources to be functional 24/7, a warm standby recovery system can be too expensive for small and medium businesses. Fortunately, there are other options to keep cloud data safe – let’s have a look at them.
2. Pilot light
Pilot light is very similar to warm standby in that both involve a scaled down copy of the primary system. The difference is that whereas warm standby handles traffic immediately, pilot light requires additional action to launch the secondary backup system. This can be a major drawback for businesses that need an immediate backup in case there is a data malfunction. However, the fact that this secondary system isn’t always running in the background makes it cheaper than warm standby.
3. Multi-site recovery
A multi-site recovery system is what we call an active-active cluster. These are high-availability configurations where the backup servers work alongside the main one. With multi-site recovery, data is distributed across two or more regions for load balance. Balance is the key concept here. Each region hosts highly available data and cross-replicates and backs up the data in the other regions. This sharing of duties translates into a higher degree of data resiliency and availability, making multi-site recovery more reliable than warm standby systems.
The bad news is that this enhanced performance doesn’t come for free. Because every region is working at the same time, multi-site recovery systems soak up a lot of resources. This can make them prohibitively expensive for small to medium businesses whose data volumes might not be as large as those of big multinationals. However, that doesn’t mean that smaller companies should relinquish cloud data recovery altogether. Let’s go over one last method.
4. Virtual replication
Virtual replication is the safest and most effective way of cloud data recovery. In a few words, it involves setting up a backup on your local site which is then replicated onto the cloud. The cloud management platform is replicated in a separate cloud region so it can be restarted in the event of failure at the primary region.
Virtual replication makes files easily accessible and available, which means that they can also be recovered swiftly. Because it provides a fully functioning copy of the source server, it enhances business continuity to an unprecedented degree. This is ideal for companies that can’t function without access to real-time data and can’t afford to wait for a back-up to be reinstated. That was the case of Fine Agro Chemicals, who rapidly recovered from a ransomware attack thanks to OGL’s cloud recovery services.
With virtual replication, you have constant access to critical data and applications even in the event of server failure. Because it provides you with an exact copy of the source server, it minimises the effects of human error, system malfunction and potential malware attacks. It’s also extremely easy to implement. All you need is an internet connection and a reliable cloud data solutions supplier.
