The process of archiving computer data to prevent loss is known as backing up. Backing up involves creating copies of data files or databases to store them securely, either on physical media (like external hard drives or USB drives) or in cloud storage solutions. This is crucial for safeguarding data against potential risks such as hardware failures, accidental deletion, or malware attacks.

In contrast, data entry refers to the act of inputting information into a system or database, which does not inherently involve any prevention of data loss. System restoration is the process of recovering data from backups or restoring a system to a previous state, which occurs after data loss has been experienced, rather than preventing it. Data compression is a technique used to reduce the size of files for efficient storage, but it does not specifically focus on preventing data loss. Therefore, backing up is the essential process that ensures data is safely stored and can be recovered in case of any issues.
