I have been trying to make Vista Backup app work with a Linux/Samba shared drive. I have Samba configured and can access it fine from the Vista box, including reads, writes and deletes. However Vista Backup always ends up failing with error 0x81000006. So is this possible? Has anybody gotten this to work? And if you have gotten it to work, will you paste your smb.conf file (my guess this is the problem)?
