WOFB snapshot fails when a sub directory on the volume contains a CD-ROM Mount Point

It is possible to mount a CD/DVD-ROM to a directory (mount point) as opposed to a Drive Letter.
When a NetBackup client has a CD/DVD-ROM drive configured in this way, it will cause a Windows Open File Backup (WOFB) job to fail the snapshot.

NetBackup does not include Removable Media (like a CD/DVD-ROM) within Backup Selections. The Windows API NetBackup uses to take a volume snapshot can not compensate for this configuration. Thus, when NBU attempts to take a snapshot of the parent volume, it fails to process correctly due to the presence of the mounted CD/DVD-ROM.
Symantec Engineering has determined that working around such a configuration requires extensive code modification and a binary can not be produced to address the issue. Therefore this issue may be fixed in a future release.
There are two known workarounds:
1. Reconfigure the CD/DVD-ROM drive to be mounted with a Drive Letter
2. Reconfigure the Policy Backup Selections to omit the path containing the CD/DVD-ROM Mount Point.
If the E:\ drive has 4 subfolders and the CD/DVD-ROM drive is mounted into E:\CD-Drive:
Configure the Policy Backup Selection like this:
This will cause the Snapshot Logic to omit the problem directory and entirely avoid the snapshot attempt of the CD/DVD-ROM.
