Howard,
        I will try to find out what kind of filesystem it is; I didn't
set it up, and can't get to it from here (long story).  
        I had already discussed wanting an outage to try the backup
without samba running, but the customer base is resisting that because
of it being a hospital environment, etc. 


Best Regards,

John D. Schneider

What file system did you use as a base? Reiser or ext3?
Have you tried running a backup with the SAMBA service down? (the whole
filesystem, yea, I know it'll take an outage).  That will help you find
out if its SAMBA causing the problem, or if it's just the file system.
And, is this a Novell OES Server by chance?  

See Ya'
Howard
