The feature that allows Aileen to keep documents updated while offline is AutoSave. AutoSave automatically saves changes to documents as they are made in compatible applications. This means that even when Aileen is not connected to the internet, the changes she makes to her documents are saved locally on her device. When she reconnects to the internet, these changes will sync with iCloud or other cloud storage services, ensuring that her documents are up to date in both local and cloud versions.

AutoSave provides a seamless experience by preventing data loss due to unexpected application closures or power outages and allows users to work on their documents without having to manually save each one. This is particularly useful for productivity, as it enables a continuous workflow without interruptions for saving.

Looking at the other options: iCloud Backup refers to backing up data to the cloud, but it doesn't directly allow document updates while offline. File History is more associated with tracking the changes to files but is not a feature integrated into macOS in the way that AutoSave is. Time Machine is a backup feature that periodically saves snapshots of your entire system, but it does not provide ongoing updates to individual documents while offline.
