A review of the Windows Application Event Log after an AVVI backup into a DeDuplication Storage Folder has completed, shows that for certain virtual machines (VMs), a number of Event ID 50001 alerts are recorded with the text given in the error message below.
EVENT ID: 50001
Description: A warning from the PDVFS driver: VmdkFilter: Failed to validate extent_map_file = C:\Program Files\Symantec\Backup Exec\Data\file extent_map_file = C:\Program Files\Symantec\Backup Exec\Data\file_extents_b_<vmname>_Date-Time for VMDK=<large number>
This warning occurs when the AVVI agent is used to backup a virtual machine to a deduplication folder and the extent map file can not be parsed by the deduplication stream handler. This is normal for Linux file systems or Virtual Machines with dynamic disks. This happens because the deduplication stream handler does not handle all types of disks in a virtual machine. This warning can be ignored. The backup still occurs successfully, but the deduplication ratio for this particular virtual machine will probably be less than supported virtual machines (for example, a Windows VM with an NTFS file system).
