D.
Enable shadow copies for the volumes that contain shared user data.

E.
None of the above

Explanation:

To create consistent backups of open files and applications, database server, and the messaging server without interrupting the applications, you need to enable shadow copies for the volumes that need to be backed up.
Applications that are running often keep their files open continuously. For backup, this can present a problem because this prevents backup applications from accessing and copying these files to backup media. Additionally, backing up servers that are running critical applications such as databases or messaging services presents a unique challenge. These applications run in a volatile state as a result of extensive optimizations that deal with huge flows of transactions and messages.
Because these applications keep their data in a constant flux between memory and disk, it is difficult to pinpoint the data that needs to be archived. The most straightforward solution is to interrupt the application during backup, which puts the data into a stable state, but might result in unacceptable amounts of downtime, particularly if the applications are large.
For both problems, the Volume Shadow Copy Service provides a solution by enabling a snapshot of the data at a given point in time, while minimizing the interruption to applications.
