Cloud Backup 2025: Which is the best choice for data protection?

CTVXNovember 7, 2025 12:00

A detailed breakdown of top cloud backup services like IDrive, pCloud, and Backblaze, helping you find the best solution based on security, price, and features.

Cloud backup services allow users to store and copy data to remote servers, providing protection against accidental deletion, ransomware attacks, and other incidents. An effective backup strategy typically follows the 3-2-1 rule: keep three copies of your data, on at least two different types of storage media, and at least one copy stored in a separate location.

It is important to distinguish between cloud backup and cloud storage. Cloud backup services not only store files but also have the ability to continuously synchronize files, ensuring that the latest versions are always updated and ready for immediate recovery when needed. Below is a detailed review of the leading cloud backup platforms today.

IDrive: The most comprehensive backup solution

IDrive is highly regarded for its flexibility, suitable for both personal and business needs. The service can handle a wide range of tasks, from backing up photos on mobile devices to protecting SQL, Exchange, and SharePoint servers.
