You could do what we do. We use "smbstatus" first to check that there are no SMB locks present (on files only - you can ignore the ones on dirs), then rename the new files out to a staging dir - then rsync that instead. It guarantees the files have been finished, and even lets the Windows users know the files have been picked up (as they disappear) -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
