Key Features of Cloud Backup Software

Some of the most important features of any cloud backup software include automated backup, remote accessibility, and version control. Other nice-to-haves might include multi-cloud support and ransomware (or other malware) protection.

Automated backup 

Cloud backup services have an automatic backup feature, allowing users to schedule routine backups of their files and data. This ensures that all files are regularly updated and protected against loss or damage, which is especially important for businesses and individuals who handle sensitive or vital information. 

With automated backup, users can focus on their businesses while knowing that their data is always secure, even without remembering to perform manual backups.

Remote accessibility

Remote accessibility allows users to access their files and data anywhere with an internet connection. This is useful for businesses with remote workers or individuals who need to access their data while on the go. 

With remote accessibility, users can work from any location without being tied to a specific device or office, which provides greater flexibility and convenience.

Version control

Version control enables users to access and recover previous versions of their files. This is crucial for businesses and individuals who must restore lost data due to accidental deletion or corruption. 

With version control, users can easily retrieve previous versions of their files, which can be a lifesaver in situations where data loss or corruption could have serious consequences.

Multi-cloud support 

Multi-cloud support allows users to back up and store their data across multiple cloud platforms. With multi-cloud support, users can distribute their data to various cloud providers, which helps protect against data loss or corruption in a service outage or other unforeseen events.

Ransomware protection 

Although not all cloud backup services provide ransomware protection, this feature is crucial for businesses that are vulnerable to cyberattacks. With ransomware protection, users can be confident that their data is protected from malicious attacks, which can cause significant harm to businesses and individuals alike.

Fulfilling the 3-2-1 Backup Rule with Cloud Backups

Cloud backups also align with the IT management best practices by following the 3-2-1 Backup Rule. This principle says organizations should have three copies of backup data in at least two different forms of storage and one off-site copy.

The introduction of online and cloud backups gives organizations another type of storage, making establishing an off-site copy more accessible than ever before.

A graphic design showing the 3-2-1 principle of data backups which states every organization should have 3 copies of its data, 2 copies living in different types of storage, and at least 1 in an off-site or cloud location.

On-premises backups vs. cloud backups

On-premises backupsCloud backups
On-premises or local backups are the tapes, disks, and flash drives holding redundant data for an organization. With physical access, administrators have more control over local backups, and system reloads are typically faster.Online and cloud backups are available via SaaS vendors hosting global data centers and remote servers for backing up client data. Though clients give up physical controls, cloud backups offer extensive remote access, scalability, and reduced overhead.

How Do I Choose the Best Cloud Backup Service and Software for My Business?

Selecting the best cloud backup services for your business can be daunting. However, there are some factors to consider in order to make the right choice, namely security, reliability, scalability, support, and of course, cost.


When it comes to cloud backup solutions, security is paramount. You want to choose a provider with robust security to keep your data safe. Look for a provider with good security measures like encryption, 2FA, and constant security audits. Fortunately, all the services we picked for this review offer these levels of security. 

Depending on your security needs, some cloud backup providers take security beyond encryption and 2FA. For instance, Acronis, in addition to the above security measures, offers cybersecurity solutions like EDR and malware and cryptojacking protection, all powered by AI. 


Reliability is another critical factor to consider when choosing your cloud backup services. Look for a provider that offers multiple backup locations and disaster recovery so you can be sure that your data is always accessible, even (or especially) in the event of a disaster. This is another area in which Acronis excels.


Choosing a cloud backup service that can scale to meet your changing business needs is essential. Look for a provider that offers flexible storage options and can easily accommodate your business as it grows. 

OneDrive is an excellent choice for scalability, with plans that can accommodate businesses of all sizes and seamlessly integrate with various Microsoft products.

Customer support

It’s essential to consider the level of customer support you’ll receive when choosing a cloud backup service for your business needs. Look for a provider with active customer support so you can get help whenever needed. 

Additionally, consider the provider’s reputation for customer service and the availability of online resources, such as tutorials and documentation. Carbonite prioritizes 24/7 support for its customers.


Cost is crucial when choosing a cloud backup service for your personal and business needs. It’s important to find a provider with pricing plans that fit your budget while offering the features and functionality required to meet your business requirements. 

Business size and storage needs should also be considered, as smaller businesses with limited storage requirements may benefit from lower-cost plans. Cloud backup services like Backblaze offer affordable plans starting at $7 per month for unlimited storage, making it a viable option for businesses on a tight budget. 


Our process for selecting the best cloud backup services and software involved a comprehensive evaluation of the most popular options.
