Backups or disaster recovery (DR)?
If you’re planning a data defense strategy for your company, it’s important to understand which strategy is best for your business needs.
While both solutions can help protect your data and critical information against unplanned disruptions and outages, sometimes backups alone aren’t enough.
Here is a breakdown of what you can expect from backups and disaster recovery solutions, so you can ensure your business keeps running even if your primary servers go down.
Remember back in college or high school when you had to write a big term paper or thesis and you would save your work to a jump drive or CD (yes, those used to be a thing) in case your computer crashed and you lost everything?
You were running a basic backup of your most critical files.
Backups work by providing quick and easy access to your data in case of smaller disruptions like outages, lost equipment, accidental deletion or hard drive crashes. This solution copies your existing information to a second storage environment. You could choose to simply back up a few important files or your entire database.
There are a few drawbacks to relying on backup solutions as your failsafe. Consider the college term paper example: If you have a sudden inspiration and write three more pages just to have your computer crash before saving your work to your backup source, you’ll have to start from the last moment you backed up. It’s the same with your business files—your data will only be updated to your previous backup.

Since many companies use backup for smaller-scale outages, in many instances they will keep their backups on-site or close to their primary facility. If these companies are hit by widespread natural disasters like hurricanes or earthquakes, there’s a chance those backups could go offline as well.
As a response, cloud-based backup options are becoming more popular because data center providers are able to offer near real-time data replication at off-site locations. In some cases, these solutions are more cost-effective and reliable for business needs.
For more large-scale outages, disaster recovery is your best option.
This solution covers more than just the major natural disasters that might immediately come to mind. In fact, only about 10 percent of unplanned outages are caused by weather. That’s behind system failure, cyber incidents and human error.
Disaster recovery solutions replicate your environment, so if there is a major disruption, an automatic failover transfers the management and operation of your infrastructure to a secondary machine and site to keep your applications and business online. Your servers will then run off your disaster recovery site until your primary facility is back online and capable of resuming system functionality.
It’s important to note that disaster recovery options come in all shapes and sizes. Synchronous solutions replicate your data in near real-time. That makes this option one of the most comprehensive, but also generally more expensive. On the other hand, asynchronous solutions have more delayed duplication, which means some of your most recent data may not be recovered.
In most cases, the best solutions involve both backups and disaster recovery.
A solid backup plan that keeps your data accessible is helpful for minor disruptions, but without a larger, more comprehensive strategy, can cause all sorts of problems for your company. For instance, if your business collects, stores or transmits information that requires strict PCI DSS or HIPAA compliance, you will want to make sure those files are properly backed up and accessible in the event of a disaster—which might not be possible with basic backup solutions.
Consider incorporating your basic backup under the umbrella of a larger disaster recovery strategy to ensure you’re fully protected. Third-party providers will offer cloud-based disaster recovery as a service (DRaaS) solutions that are often more cost-effective and appropriate for your business needs.
Do your homework and determine the best strategy for your company. Because it’s not a question of if, but when you’ll need to recover from an unplanned outage.
