When you hear the term "disaster recovery," what comes to mind? One common thought might be restoring or continuing a system after any disaster strikes, ensuring that it remains operational. In the context of cloud computing, this concept of disaster recovery is relatively new. But have you considered the concerns people often have about cloud disaster recovery? Is it the right choice for your organization? Let’s explore these questions together.
Cloud-based disaster recovery (DRaaS) is still a developing field, encompassing various products and services. Small and medium-sized enterprises (SMEs) are beginning to leverage cloud services for disaster recovery. Deploying disaster recovery sites in the cloud minimizes the need for physical data centers, reduces the reliance on IT infrastructure, and significantly cuts costs. This allows smaller organizations to access solutions previously only available to larger enterprises. As cloud-based disaster recovery becomes more widespread, discussions around data center space are shifting toward cloud computing capacity planning.
No solution is without its flaws, however. Even perfection is rare. Before implementing any disaster recovery strategy, it’s crucial to understand both the benefits and limitations. If you’re using cloud-based backup as part of your disaster recovery plan, designing the recovery process for your backup sets is essential. Other considerations include the customer service capabilities, availability, and reliability of cloud service providers.
For disaster recovery in cloud computing, there’s no one-size-fits-all blueprint like traditional disaster recovery. Each organization operates uniquely, depending on the applications they run and how critical those applications are to their business. As a result, disaster recovery plans in cloud computing vary across organizations. A principle known as “diversion†helps create cloud-based disaster recovery plans. This principle, which applies to traditional disaster recovery, can also be used in cloud computing. The process of creating a disaster recovery plan can be summarized as follows:
- Identify and prioritize applications, data, and services.
- Calculate downtime for each application, service, and data.
- Identify all critical resources and recovery methods.
- Determine effective ways to meet the Recovery Time Objective (RTO).
Alternative disaster recovery solutions in the cloud offer organizations multiple choices. Let’s review these options.
**Managed disaster recovery and managed applications**:
One of the best-known options is migrating disaster recovery instances and primary production to cloud computing and outsourcing it to a Management Service Provider (MSP). You can enjoy all the benefits of cloud computing, from eliminating infrastructure to cutting costs. What’s even better is that you can delegate disaster recovery management to service providers or cloud computing services. The key is choosing the right provider and negotiating an appropriate Service Level Agreement (SLA). By delegating responsibility to service providers, you ensure they maintain uninterrupted service within the SLA-defined framework. Traditional cloud computing vendors are increasingly offering email and commercial applications like customer relationship management.
**Backup and restore from cloud computing**:
In this approach, maintaining data and application backups is crucial. While data backup happens in the cloud, restoration occurs on hardware when a disaster strikes. Essentially, this replaces traditional tape-based offsite backups with cloud-based ones.
During the process of cloud computing backup and recovery, several challenges arise, particularly regarding the restore and backup functions. While the backup process itself is straightforward, backend application providers are now expanding their backup solutions to replace direct backup services provided by major cloud service providers. Similarly, cloud gateways can be used to migrate data to the cloud. These gateways combine cloud storage and on-premise storage, keeping cloud and on-premise data synchronized.
Restoration is the most complex aspect of deploying cloud-based backup disaster recovery. Restoring terabytes of data faces bandwidth limitations, making recovery under such circumstances challenging. Some cloud backup vendors restore data directly to disks, where customers retrieve and recover the data themselves. Another option is to use a large local cache for the latest backup for on-premise recovery.
If data recovery is a priority, features like compression become vital. Restoring data from the cloud to on-premise infrastructure is a viable option.
**Backup and restore to cloud computing**:
Here, data recovery doesn’t happen in on-premise infrastructure but in virtual machines stored in the cloud. To implement this, you’ll need cloud computing resources and storage. The recovery process can occur either before or immediately after a disaster. Setting a predetermined recovery date is critical, especially in meeting stringent RTO requirements. Some cloud service providers are expanding their offerings to include cloud computing virtual machines as part of their disaster recovery solutions.
**Copy data to a virtual machine in the cloud**:
Some applications require significant recovery time, such as those with high recovery point objectives (RPO) or real-time awareness. In such cases, copying data to virtual machines is a viable option for transferring data. This solution can be deployed between on-premise production instances and cloud computing. Replication involves moving virtual machine data from on-premise to the cloud or vice versa.
Cloud computing provides more options for disaster recovery while significantly reducing costs. However, the fundamental principles of disaster recovery remain unchanged—people must develop specific plans, conduct regular tests, and train users to prepare for disasters.

Cloud-based disaster recovery continues to evolve, offering new possibilities and challenges. As organizations adapt to this rapidly changing landscape, understanding these solutions becomes increasingly important. Whether you’re considering managed disaster recovery, cloud backup, or virtual machine replication, each option brings its own set of advantages and considerations. Cloud computing has opened up exciting opportunities, but careful planning and execution are essential to ensure success.
