Backup Review was established in 2004 to provide objective and timely information to buyers of online backup and storage services.
The online backup and storage industry is enjoying a rapid growth and is expected to grow along with the availability of broadband Internet for years to come. As such, there are a growing number of providers entering the market. This is great for buyers, as greater competition lowers cost and increases choice.
However, it also makes it a lot harder to choose the right provider. Backup Review helps potential users make the right choice by providing all relevant information, including monthly ranking of the top 25 providers.
