How often should you back up your computer data?

Computer users should back up their data immediately after they have created new files or made changes to already existing files that may be difficult to recreate. Performing regular backups is the only way to guarantee the safety of the data.

Data is the most crucial component of a computer system. Hardware can be replaced and software can be re-installed, but it is difficult to recreate original data that has been completely lost. The Windows operating system allows users to automatically back up data, but it can also be done manually by copying critical files to a secondary protected system that can be accessed easily.
