On page 865 of the admin's guide it states:
The Advanced Disk-based Backup Option provides the following features:
■ Synthetic backup. This feature uses a policy to enable a full backup to be assembled,
or synthesized, from a baseline and subsequent incremental backups that are also
contained in a policy. The benefits of using a synthetic backup include:
■ A reduced backup window since the synthetic backup can be scheduled outside
of the time-critical backup window.
■ Reduced network traffic since the synthetic backup does not need to access the
network.
■ True image restore. This feature enables Backup Exec to restore the contents of
directories to what they were at the time of any full or incremental backup.
Restore selections are made from a view of the directories as they existed at the time
of the particular backup. Files that were deleted before the time of the backup are
not restored. In true image restore, only the correct versions of files are restored
from the appropriate full or incremental backups that contain them. Previous
versions are not unnecessarily restored and then overwritten.
■ Offhost backup. This feature enables the backup operation to be processed on a
Backup Exec media server instead of on the remote computer, or host computer.
Moving the backup from the remote computer to a media server enables better
backup performance and frees the remote computer as well.
This is an added on feature that will allow you to use true image restore.
Here is a link to the Admin's Guide, it goes further in to detail about the option:
