6 data backup service providers to watch

Evaluate how offerings from six prominent BaaS providers differ when it comes to considerations such as pricing, scope of coverage and the amount of data they can back up.

Backup as a service offers an alternative to traditional storage methods. Data backup service providers can use this off-site storage method to back up an organization's files, folders or hard drives to a remote secure public cloud. This helps protect the data from cyberattacks, ransomware, natural disasters and user error by making the data recoverable from a remote backup repository.

Backup as a service, or BaaS, refers to a data protection architecture in which the backup server runs in the cloud as a managed service the backup vendor maintains. This online backup service typically also provides cloud storage for backup and data protection. Some providers, however, require that organizations use third-party clouds, such as AWS or Microsoft Azure, as a backup target.

BaaS providers vary in terms of what they can back up. Some cloud backup service providers offer comprehensive data protection services and can back up almost anything. Others, however, are more niche in their scope and might focus on protecting a particular hypervisor or a specific SaaS application, such as Microsoft 365.

What types of organizations use BaaS?

There are BaaS offerings to fit almost every organization's needs. Some providers offer enterprise backup as a service, while others offer services that are more suitable for SMBs. An organization should consider BaaS if its current backup tool is leaving gaps in coverage or isn't fully meeting its needs.

BaaS is also a good option for organizations that have employees working from home and saving data on their own personal devices. Some BaaS providers will enable organizations to back up these end-user devices, thereby protecting otherwise vulnerable data.

How top backup-as-a-service offerings compare

Key differences between on-premises and cloud-based backup

Modern BaaS offerings often mimic backup products that are designed to run on premises, but there are some key differences, including the following:

  • BaaS is only available as a subscription, whereas some on-premises backup offerings are still available with a perpetual license.
  • BaaS providers typically require data to be backed up to cloud storage.
  • Some data backup service providers have capacity or data type restrictions. For example, a BaaS provider may not support backing up video files or might prohibit the backup of files over a certain size.
  • Unless an organization is using a cloud storage gateway, BaaS will be slower than an on-premises product, as it uses a WAN connection to back up and restore data.

Advantages of BaaS

The popularity of BaaS is largely due to its many benefits. Each BaaS provider has its own way of doing things, but generally speaking, there are several benefits an organization can expect to gain from an enterprise backup-as-a-service offering. These include the following:

  • An organization can automate long-term data retention, which is essential for complying with regulatory retention requirements.
  • Data is encrypted at rest and in flight, providing protection against hackers and ransomware.
  • Data is stored off site, often in multiple locations. This provides protection against natural disasters and human error.
  • Admins can offload backup server-related maintenance and management tasks to the provider.
  • An organization can easily recover backed up data that's lost or deleted.
  • Redundancy enables an organization to store multiple copies of the same data in separate locations.
  • BaaS can be less expensive than other backup techniques, since an organization doesn't have to purchase backup hardware or media.

Questions to ask before selecting a BaaS provider

Although data backup service providers generally do a good job, they aren't all created equally. They differ widely when it comes to such considerations as price, scope of coverage and the amount of data they can back up. As such, it's critical to consider the following key questions before signing a contract with a BaaS provider.

  • What data and devices does the organization need to back up?
  • How often do backups need to run?
  • What compliance requirements does the organization need to meet?
  • How quickly does the organization need to recover following a data loss event?
  • What are the organization's recovery time objectives and recovery point objectives?
  • What type of security measures does the organization need the BaaS offering to provide?
  • What is the organization's budget for a cloud-based backup?

There are numerous cloud-based services. Let's examine six of the more prominent BaaS vendors and their offerings.

Acronis Cyber Backup

Acronis Cyber Backup can protect more than 20 platforms, including physical and virtual machines, PCs and mobile devices, and NAS appliances. It offers bare-metal recovery capabilities, as well as a restore anywhere feature that can restore backups to dissimilar hardware or perform physical-to-virtual conversions. The software can also perform granular recovery operations, such as recovering an individual email message.

Acronis offers several noteworthy features to keep backups secure, including an AI-powered anti-ransomware feature. The software also generates a CyberFit score that helps organizations assess their level of protection.

Acronis provides features such as blockchain backup notarization, retention rules and backup replication to help even the largest organizations manage and ensure the integrity of their backups.

Acronis Cyber Backup is licensed by subscription, with one-, two- and three-year plans available. Like the BaaS version, the on-premises version is available as a one-, two- or three-year subscription. A perpetual license is also available for the on-premises version.

Acronis provides significant online documentation and assistance with various issues on their support site. Additionally, customers can also contact the support department by email.

Carbonite Cloud Backup

Carbonite Cloud Backup was one of the first BaaS products on the market. It offers cloud backup services for individuals and SMBs, and the Carbonite Endpoint service provides endpoint backup capabilities for large, distributed organizations. Carbonite is entirely cloud-based and doesn't offer an on-premises backup product.

Carbonite's primary security is its backup encryption, which includes 128-bit encryption for backing up a single computer or multiple computers. The Computers and Servers plan, which addresses small businesses, includes both 128- and 256-bit encryption. Carbonite's Webroot SecureAnywhere Antivirus subscription offers additional optional support for a single computer.

Other noteworthy features include support for the Family Educational Rights and Privacy Act, the Gramm-Leach-Bliley Act and HIPAA, as well as remote file access to computer files and a centralized administrative console.

Carbonite creates image-based backups of protected machines and supports bare-metal restores, as well as the recovery of individual files and folders. The Computers and Servers plan also enables admins to back up and restore databases and applications.

Carbonite offers three main data protection plans: The One Computer plan starts at $6 per month. The Multiple Computers Plan starts at $24 per month, and the Computers and Servers plan starts at $50 per month. These plans are billed annually, with one-, two- and three-year subscriptions available. There are additional charges to protect more devices than the plan covers and for additional cloud storage. The multi-computer backup plan, for example, covers up to 25 computers and includes 250 GB of storage.

Carbonite provides 24/7 support via phone, chat or email, and provides help through an online knowledgebase.


Clumio is an enterprise-grade BaaS provider that focuses primarily on protecting AWS, Microsoft 365 and VMware resources. Clumio allows admins to create a single set of backup policies and apply it to all workloads, regardless of where they reside.
