Best Cloud Backup Services for 2021
With the expansion of high technologies and millions of data, the problem of losing any of the data becomes more serious. The sensitive data on personal devices or computers are prone to damage or loss caused by mechanical failure. Cloud backup is, so far, the best means to protect data and restore it in case of a crash.
Cloud backup or online backup is the tech service of sending data to a secondary server or a data storage system. A third-party service offers the consumer data storage space or access to data or restores it anytime needed. This technology is a key solution for companies to switch to more flexible data storage from physical devices to the cloud and reduce costs.
As an IT segment, cloud computing generated over $300 billion in revenue in 2020. Moreover, already 81% of all enterprises have implemented a multi-cloud strategy. In 2020, 67% of business infrastructure was transformed into cloud-based, and it is predicted that up to 94% of the global workload will be controlled by cloud servers shortly. It becomes evident that cloud backup is an important, even vital, technology.
In this post I will offer you a comprehensive analysis of the best cloud backup systems you can find, listing their pros and cons so that you can choose the solution most suitable to your needs.
Types of Clouds and Cloud Service Models
First of all, a clarification. “Cloud storage” and “cloud backup” are not synonymous. The former is a remote storage drive to save data and access it through the internet. On the other hand, cloud backup includes the functionality of cloud storage, plus it grabs all the data from the device and stores it in a cloud. Typically, cloud storage and cloud backup—alongside cloud sync—operate within the same software.
Generally, we can divide cloud into three separate categories: public, private, and hybrid:
- Public cloud is owned by a third-party service provider and delivers services across the internet. The user gets access to the cloud services and manages their account through a web browser or a mobile app.
- Private cloud, on the other hand, delivers services within an organization. Cloud computing services and resources are used by a single company and its members who have access. The cloud may be located on the on-site data center of the company or hosted by a third-party service provider.
- Hybrid cloud offers both types of cloud usage. The flexible solution of hybrid cloud suggests a smooth switch between public and private clouds.
Besides this basic division, we can also categorize cloud services according to their models: Software as a Service (SaaS), Platform as a Service (PaaS), or Infrastructure as a Service (IaaS):
- Software as a Service (SaaS) offers data access from the device or a web browser with a network connection. This way the provider gives end-users network-based access to a single copy of an app created for SaaS distribution. At the same time, the cloud providers can manage the software app with SaaS and handle any maintenance like updates or security patching. With a compound annual growth rate of 18%, the SaaS market will reach a value of $623 billion by 2023.
- Platform as a Service (PaaS). The PaaS model supplies an environment for developing an app and managing its future maintenance. The technology is more popular in mobile app development. It helps build an app faster without setting up the underlying infrastructure of servers and storage. Simply put, developers are renting everything needed to build an app from a cloud provider.
- Infrastructure as a Service (IaaS). The form of cloud computing delivers on-demand resources like storage and network to consumers over the internet. Due to the rise of PaaS, the IaaS technology registered a fall. Still, by 2027, the IaaS market will be valued at $201 billion.
With hundreds of free and paid cloud services, it is vital to find a reliable one that will meet your requirements and provide secure backup and storage. After all, you are going to entrust this cloud with some really important parts of your life.

Ultimately, it’s a matter of balance. Ideally, there would be a solution that would combine high performance and versatility of features and robust security at a low price—or, why not, even free. But there is no such option, so it’s a matter of finding the balance suitable to your needs.
Apart from these attributes above, you should also consider storage space options, the scalability of the service, the frequency of backups, and vendor disaster recovery.
