Backing up FreeNAS server with Backup Direct

We are trying to evaluate how to back up a FreeNAS server using Backup Direct. We have limited success so far.
What has shown up is an issue in FreeNAS when using anonymous user authenication for Windows users. Several threads appear in the FreeNAS forum associated with this problem.
We are putting a link to our thread on the FreeNAS forum if you need to look further.

Click http://sourceforge.net/apps/phpbb/freenas/viewtopic.php?f=21&t=7076 for further information.

I have also had input on another forum related to this subject. Click http://ubuntuforums.org/showthread.php?t=1384007 or http://ubuntuforums.org/showpost.php?p=9535918&postcount=6 to look at Samba configuration issues on FreeNAS.

Postscript. We have now found iceBackup which seems less trouble than BackupDirect although it cannot cope with users on FreeNAS with UID 21.
