What is the purpose of data backup?

The purpose of data backup is fundamentally about safeguarding information by creating copies of data that can be restored in case of loss, corruption, or damage. This is crucial because data is often vulnerable to threats such as accidental deletion, hardware failures, malware attacks, or natural disasters. By having a reliable backup, individuals and organizations can ensure continuity and recovery of critical information without significant disruption.

In contrast, increasing storage capacity focuses on expanding the amount of data that can be stored, rather than protecting existing data. Transferring data to other devices pertains to the movement of data rather than ensuring its safety, while improving processing speed is related to the performance of systems and applications, not to the security or preservation of data. Thus, the intention behind data backup clearly aligns with creating copies for protection against potential data loss or corruption.
