Which option best describes an operation performed during backup or restore?

The operation of ensuring data integrity is crucial during backup or restore processes. This refers to the need to verify that the data being backed up is accurate, complete, and unaltered from its original state. When performing backups, systems employ various methods to check that data is correctly copied and is retrievable without errors. During a restore process, similar checks occur to confirm that the data being restored has not been corrupted and aligns perfectly with what was intended to be retrieved.

Ensuring data integrity is fundamental because it safeguards against potential issues that could arise from restoring corrupted or incomplete data, which might lead to machine errors or operational disruptions. This focus on verification during backup and restore is what maintains the reliability of operations conducted through the FANUC systems.
