Cloud backup is a process in which data stored in a physical location is replicated and sent over a network to another, remote, location in the cloud to protect it from loss or corruption. Organizations choose information backup in the cloud to keep their data safe and accessible in case of a hardware or software failure, outage, or disaster—either natural or a cyberattack such as ransomware. Because all backup software and infrastructure is hosted and managed by the cloud provider, cloud backup is also known as backup as a service (BaaS).
Cloud backup keeps data safe and protected. It automates the copying and safeguarding of data in a remote location. Without protection like this, organizations could lose valuable data during hurricanes, floods, system failures, or cyberattacks.
The popularity of cloud backup is growing because organizations are increasingly dependent upon their data for daily operations. Many on-premises backup solutions require copies of data to be physically transported to an offsite location regularly and physically retrieved if restoration is required. Because this process involves many manual steps, it is more time consuming and less reliable than cloud-based backup and recovery.
Cloud backup solutions are:
Cloud storage and cloud backup share a common goal: to securely store data in a safe, offsite location, and make it easy to retrieve when organizations need it. Both use the cloud as the destination for data. Both are highly scalable—giving teams as much capacity as needed. After that, differences exist.
Cloud storage supplements on-prem data storage, only in an offsite location in the cloud. It gives you access to the data stored within it from anywhere, at any time, using any device with an internet connection.
Cloud backup, in contrast, is specifically designed to replicate and store data so you can restore it if it is lost or damaged.
Another important difference between the two is this: cloud storage is a manual process. You have to physically enter all the files you want to be stored in the cloud. Alternatively, most BaaS options automatically save files stored onsite, based on the preferences you set through policies.
There are also differences in security. With cloud storage, your data files are encrypted only when they reach the cloud server, not before. Cloud backup or BaaS solutions, on the other hand, encrypt files before transferring them to the cloud, making the operation more secure.
The best cloud backup solutions meet the following criteria:
Free cloud backup services are typically limited-time offers (such as 30-day trials at no charge) to give organizations access to full-featured solutions without having to make financial commitments upfront. Fewer operate a “freemium” model, in which you get a limited form of the service for free, but pay a monthly (or annual) subscription fee to get additional functionality. This model tends to limit the volume of files or data you can back up. With any free backup service, it will be important to ask about security and privacy practices, including rapid ransomware recovery.
While free is a good way to test a solution, businesses generally need to pay for a robust backup service to get the comprehensive ongoing backup support they require.
Cloud backup costs vary, typically with a discount if you commit to a year or more of service. That said, price ranges depend on a number of factors, including how much data can be stored, how fast data can be restored, and customer service response times.
The short answer is as safe as your backup onsite. The chief benefit of backing up your data offsite, away from the office, is that it’s safer from physical theft, fire, and other local (and physical) disasters.
But cloud-based backup is still prone to virtual risks, such as cybercriminals—both inside and external to your organization—that could make your data vulnerable.
You can be reassured that leading cloud backup providers are likely to be secure as they utilize extremely robust cybersecurity measures—such as encryption, multifactor authentication, and immutability—to protect data against breaches. And by storing your data in an offsite cloud, you can protect your data against threats like ransomware.
Additionally, leading cloud backup vendors provide 24/7 monitoring, management, and reporting to ensure your data remains safe.
Cloud backup is increasingly seen as an optimal way to keep your data safe from loss. It’s also cost effective, as you don’t have to invest capital in storage infrastructure and pay skilled personnel to manage that infrastructure.
There are a handful of potential disadvantages to moving your data backup to the cloud. Here are the top three. They can be easily mitigated however by choosing the right cloud backup provider.
