Hi Micheal, qvindesland

Thanks for your replies.  I would like to refrain from some other backup
tool as much as possible as I have a number of other servers which I am
backing up with ntbackup.

I should explain some things more clearly.

1. The samba share was a windows file share before.  I migrated the share
only to the debian box.

2. I am only looking to backup the share data and not the server itself. 
That is done by some other means.

3. On Windows I used ntbackup to perform a normal backup once a week to a
removable hard drive for the share only.  The daily differential backups go
to the same device and I  maintain them in a seperate bkf.  This only
includes files that changed since my last normal backup.  From my
understanding this is because the archive attribute gets cleared on a normal
backups.  This saves me some space and time.  Since I moved to the samba
share I am unable to maintain this strategy as the archive attribute does
not seem to work the same way. 

4. For example, if I change the attribute (uncheck) and then change the file
content, the attribute does not get checked (this works on windows ntfs). 
On samba, this does nothing to the checkbox.  Also, I have noticed that once
I change a file, the created, modified and accessed time stamps seem to
change altogether.  What options do I use to keep these consistent to
windows behaviour.

Thank you
