Dell EMC PowerProtect DD

Offers high-speed, inline deduplication that revolutionises disk backup, archiving, and disaster recovery

Plaudits of the solution highlight its excellent deduplication features and appreciate the scalability it offers. Coupled with its ability to handle large capacities with little management, the product is both simple to use and capable of maintaining high levels of performance simultaneously. Despite this, there are a couple of areas where PowerProtect DD could be improved, with critics arguing that it should have better integration options and a stronger focus on security.   

HPE StoreOnce

A data backup solution that provides a consistent, high-performance, scale-out architecture for the whole enterprise

Achieving an average rating of 8.3 from 12 reviews, HPE StoreOnce is another high-profile choice available to users.
