What process is involved in copying or saving data to prevent loss during a computer failure?

The process involved in copying or saving data to prevent loss during a computer failure is known as backup. Creating a backup involves making copies of important data and storing them in a separate location, which can be easily accessed or restored in the event of data loss due to system failures, accidental deletions, or other unforeseen circumstances. This practice is crucial for ensuring data integrity and security, allowing users to recover their information without significant disruption.

While other processes like restoration, replication, and archiving serve important functions, they do not specifically focus on the immediate need to create a safeguard against data loss. Restoration refers to retrieving data from a backup, replication involves creating real-time copies of data for consistency across different systems, and archiving pertains to storing data that is no longer actively used but may be needed for future reference. In contrast, backups are fundamentally about creating those copies in the first place to ensure data safety.
