Which menu path do you follow to adjust how often a backup file (.cbak) is saved?

The correct answer involves selecting Tools > Options > Global because this pathway provides access to the overarching settings that affect the program as a whole. Specifically, the Global options allow users to modify settings that are not limited to individual cases but apply universally across all cases being managed in EnCase. Within this section, users can adjust settings such as how often backups of cases are created and saved, which is crucial for data preservation and recovery.

This adjustment is important as it can influence the frequency of secure backups, thus protecting against data loss. The other options, while they do have menus that include 'Options' related to 'Case Options', do not lead to the correct setting for backup frequency, as those paths typically pertain to configurations that only affect the active case rather than the global application settings.
