What feature allows users to create a backup of the current session while preserving the original?

The option that allows users to create a backup of the current session while preserving the original is "Save Copy In." This feature is designed specifically for creating a duplicate of the current session, which can include all the necessary audio files, MIDI files, and session settings. When you use "Save Copy In," Pro Tools allows you to specify which components of the session you want to include in the backup, making it a flexible tool for session management.

This function is particularly useful for archiving purposes or when you want to send a session to another user without affecting the original version. It ensures that the original session remains intact while you work with or modify the backup copy. It can also simplify sharing sessions across different operating systems or versions, as you have control over what to include in the backup.

In contrast, other choices such as "Save Session As" creates a new version of the session but does not offer the flexibility to manage or specify the contents of a backup in the same way that "Save Copy In" does. "Session Backup" is not a standard feature in Pro Tools terminology, and "File Export" generally refers to exporting audio or MIDI files rather than saving an entire session as a backup. Thus, "Save Copy In" stands out
