Backup Exec Deduplication Storage Folder Recovery
The following section details the steps required to bring the Deduplication Storage Folder back online
after the post-OS Upgrade steps are completed.
1. If the DSF had been created manually, then proceed to step 8.
2. During the Windows Server 2008 R2 Upgrade, Windows removes the mount path for the
automatically provisioned Deduplication Storage Folder (DSF).
3. Backup Exec indicates that the DSF is offline and the DSF will remain in that state until the DSF
mount path has been restored.

4. Using an account with system administrator privileges, launch a command window:
Start -> Run “cmd”
5. Create the PDDE_Volume folder in the Backup Exec folder with the following command:
MKDIR "C:\Program Files\Symantec\Backup Exec\PDDE_Volume"
6. Run DISKPART and issue the following commands:
a. LIST VOLUME
b. Locate the DSF volume by the drive letter you assigned prior to the OS upgrade, e.g.
“K”. (See step 2c in the Marking the Backup Exec Deduplication Storage Folder
section)
