More to say, backup solutions are usually requested to be flexible, feature-rich and utilize different storage-optimization technologies for increased cost-efficiency. The additional requirement of the long-term data retention significantly increases the overall cost of the final solution, which resulted in an increased demand for public clouds like Amazon Web Services and Azure as a backup repository for their data.
