Computers have become the new information store for most people. Organizations, companies and individuals store most of their information in the form of files in computers. Most of the information stored is confidential and important. However safe we might think that computers are, we should always remember that they are not always safe. Computers and computer programs are prone to errors and technical problems. This problem in most cases leads to loss of data. Data loss can be as a result of computer viruses, fire, floods, theft, and file corruption among others. Loss of data can lead to loss of information such as customer information, financial information, employee’s data, other files.
To avoid such data losses, there is a need to back your data in an external storage device. Data backup is the process or the act of archiving, or copying files, and folders for the purpose of being able to restore them in case they are lost. There are various considerations that you should make while deciding the best data backup plan.
One of the major decisions is what data, i.e. files and folders to backup. Generally, you should back up the data that cannot be easily replaced. This could be access databases, word documents, spreadsheets, and other files that would be hard to replace. Program files cannot be backed up. They will need to be reinstalled if they are lost.
The second consideration is which compression to use. Compressing of files ensures that they are as small as possible. You can use your preferred compression method. Have in mind that some files will not compress very much.
Thirdly, you should determine how often you will be running the data backup. This mostly depends on how often the data changes. Data that changes hourly may need hourly backup. Data that changes in a few days may require a weekly update.
Lastly, you should consider what storage media to back your data in. There are various data storage media that you can use for data backup. They include, additional local hard drive, external drives, optical discs and the virtual disc space.
