The Time Machine Heal function in NDB is designed to address inconsistencies or gaps in the Time Machine's restore point chain, ensuring a continuous and reliable recovery history. It identifies and repairs missing log backups or snapshots that may have been skipped due to failures (e.g., network issues or agent errors), thereby removing gaps in the restore capability. This function does not patch software, refresh clones, or restore from malware but focuses on maintaining the integrity of the Time Machine's data protection timeline.
Other options are incorrect:
* A. Patches a Time Machine to the latest NDB levels: This is a software update, not a heal function's purpose.
* C. Refreshes a database clone in Time Machine: Clone refresh is a separate operation, not related to healing.
* D. Restores a Time Machine from snapshot in the event of malware: Restoration is a distinct action, while heal addresses data gaps.
Thus, the verified answer is B, reflecting the heal function's role in restore continuity.
