Method To Create DDS
This section describes the various methods that were used to create the DDS. It also applies to a DSF that was created
on an appliance that was previously running Backup Exec 2010 and later upgraded to Backup Exec 2012. Use the method
discussed in this section to decide which column to follow in the specific solution maps.
• Automatic Disk Configuration—This refers to a DSF that was automatically configured using the Storage
Provisioning option. This automatically creates the desired RAID group on raw physical disks and configures the
DSF or DDS under the C:\Program Files\Symantec\Backup Exec\PDDE_Volume mount point
• Manually Configured from Backup Exec Console —This refers to a DSF or DDS that was configured by
navigating to the Backup Exec console, right-clicking on an Unconfigured virtual disk and specifying to
configure the virtual disk as a DSF or DDS. This option was only available starting in Backup Exec 2010 R2. This
configures the DSF or DDS under the C:\Program Files\Symantec\Backup Exec\PDDE_Volume mount point
• New Deduplication Storage Folder Wizard on Drive Letter—This refers to a DSF that was created on a Drive
Letter in Backup Exec 2010 using the New Deduplication Storage Folder Wizard and then later upgraded to
Backup Exec 2012. After the upgrade, the DSF still remains on the same drive letter.
