A recent test of online backup services by a German IT security publication Heise found that Mozy and Carbonite were both services safer with broad protection against many types of hacker attacks.
Heise concluded that each of the six online backup services have tested quite complex security measures, but in some cases, they left loopholes open to curious elementary criminals. As indicated in the report Heise:
[Online backup services] say they store customer data safely, some basic safety measures they take are implemented so carelessly and unprofessionally they can easily be overcome
.
Mozy and Carbonite, the only two services we reviewed that were included in the Heise test, both thwarted successfully all attempts by the testers to get unauthorized data stored either on the service. Heise gave the slight edge to Mozy as the preferred test team stevedoring companies of certain types of hacker attacks.
While we already think highly of these two services, we are pleased to see an additional independent verification of quality of the security perspective. You can learn more about Mozy, Carbonite and other online backup services, visit our online backup service comparator.
