Empty folders within Sharepoint document libraries are missing after granular restore

Hello everybody,

I'm testing Backup Exec 2010 with Sharepoint (MOSS) 2007. And I have the same problem like this one : http://seer.entsupport.symantec.com/docs/314140.htm
I can't restore empty folders (in fact there are missing after the restore operation), and there is no error message.

Anyone can help me ? Do you know any tips for this problem ?

Thanks for your help.

Regards,

David
