The standard backup procedure for the Avaya Messaging solution, as defined in the official administration guide, specifically targets three critical folders to ensure a complete and successful restoration. These folders are UC\DB, which contains the system configuration and user data; UC\Messages, which stores all user voice, fax, and email messages; and UC\Prompts, which holds the system's audio prompts. Backing up these three directories captures all essential data required to restore the system to its operational state.

A. UC\DBCom: This folder is not specified in the standard backup procedure. The primary database files and configuration are located in the UC\DB folder.

B. UC\Licenses: While license files are critical for system operation, they are not included in the data backup process performed by the standard Avaya Messaging backup utility.
