I am finally trying to do a live upload with s3cmd sync and now I am getting the following error message:

It is very possible that the file in question was create temporally and then removed from the directory later, while the system was gathering files.  This is one of the reasons that I excluded the /opt/backup directory.  Also that directory is one that I am using for my local backup and do not want to send it to Amazon.  I am not familiar with python, but it seems to me that the script should ignore a file that is no longer present, or at least give me a warning and continue on.  It should not crash when this happens.
