With online data backup, files are available to the user anywhere there is Internet access. However, these data files face a risk of unauthorized access from hackers. To keep files safe and private you must encrypt your files as Internet hackers may interfere with files which are not properly encrypted. For this reason it is also advisable not to upload highly sensitive information to those public online backup systems which do not require payments. To find the best service provider for your needs, carefully read and understand their policy, terms and conditions. Limited control of your data files When you back up your files, these end up in the hands of the service provider; this means that you can’t control how they handle your data especially as in some cases the provider has millions of data files to manage. Unfortunately, mishandling of files leads to the loss or exposure of data to unauthorized parties, and the volume of data makes the risk of pilferage quite high. Dependence on the Internet for business operations When a company adopts an online backup as their preferred data storage method, all their operations become dependent on the Internet. This means that the company will incur in higher costs to maintain an up-to-date technology as the absence of Internet connection leads therefore to failure in business operations. Increase in bandwidth to support backup Data transfer from a computer to the Internet is measured in megabytes or gigabytes. Organizations that use online backup require larger bandwidth than they used before, thus incurring in extra costs. Slow initial backup of files Slow backup is common with organizations because they upload large files. The larger the files, the larger the bandwidth the organization needs for file upload.
