Backing up Samba shares with Seagate Backup Exec for NT

[Jrauch at Cnuber.com]

Hello,
 
Does anyone have experience backing up their samba SMB shares with an
NT-based backup system? I'm using Seagate Backup Exec 7.0, and whenever I
select a share on Samba, I get a message saying "Unable to connect to
server, <F5> to retry", and then another one saying "A device specefic error
occured". My samba shares are all fully operational (I can access them from
a client workstation without problems), and I use Backup Exec with other NT
shares all the time. 
 
Any ideas, or comments on this method of backup are greatly appreciated!
 
Thanks,
John Rauch
