Today’s network attached storage (NAS) devices offer myriad capabilities beyond data storage and retrieval—and, when coupled with a NAS cloud backup option, can provide enterprises with unprecedented levels of digital resilience for their data. With a wide range of solutions on the market, enterprises can pick and choose the right NAS cloud backup for their needs.

We evaluated the top 10 competitors to see how well they compared on core and enterprise features, integrations, customer support, and price—here are our picks for the five best NAS cloud backup solutions of 2023:

Read on for more detail about all 10 of the NAS cloud backup solutions we evaluated.

Top NAS Cloud Backup Solution Comparison

A NAS cloud backup solution effectively acts as a backup counterpart to a local network attached storage device. If the NAS device experiences a hardware failure or is otherwise compromised, the backup allows the organization’s data to be safely recovered from the cloud.

Providing this extra layer of redundancy is just a baseline requirement these days. Leading enterprise NAS cloud backup solutions offer a range of additional features, including automatic backup scheduling, in-cloud data collaboration, and advanced security options. The chart below shows how the top 10 solutions compared against our evaluation criteria.

Key Features of NAS Cloud Backup Software

At the core of NAS cloud backup efforts is the data itself, and with that comes all of the relevant security, compliance, privacy, and availability considerations. The following key features address these concerns and more, and should be top-of-mind when evaluating NAS cloud backup software solutions.

Backup and Restore Tools

NAS cloud backup solutions offer various data storage capabilities. Be sure to verify that candidate solutions satisfy your current and future data storage bandwidth and capacity requirements. You should also ensure that the solution is compatible with your organization’s NAS devices and operating systems, and is capable of seamless and reliable synchronization across devices.

Security and Compliance Controls

Security features like encryption and multi-factor authentication (MFA) should be hard requirements, both generally as best practice—but also potentially as a legal mandate. If your organization is subject to compliance requirements or data privacy/security regulations, these security features may be non-negotiable.

Web and/or Application UI

The solution should provide a user-friendly interface for simplifying management and maintenance tasks, coupled with automation and scheduling options that are easy to access and configure.

Collaboration Tools

A competent NAS cloud backup solution should offer collaboration features like file sharing and access control management, enabling teams to view and manage data collectively in the NAS cloud backup environment.
