 * My php error log becomes several megabytes big during a backup with errors of
   the type:
 * [27-May-2013 09:30:51 UTC] WordPress database error Duplicate entry ‘/home5/andrexw1/
   public_html/blog/wp-content/plugins/w3-total-cac’ for key ‘file’ for query INSERT
   INTO `cb1w01b3gd_wpb2d_processed_files` (`file`) VALUES (‘/home5/andrexw1/public_html/
   blog/wp-content/plugins/w3-total-cache/wp-content/object-cache.php’) made by 
   do_action_ref_array, call_user_func_array, run_dropbox_backup, WP_Backup->execute,
   WP_Backup->backup_path, WP_Backup_Processed_Files->add_files
 * It appears to do this for plugins, themes, uploads, etc. I can not detect a discernible
   pattern to it. But like I said, the errors are persistent and numerous to the
   point that the error log becomes megabytes large (last one was ~8mb). I am using
   the premium zip extension, as well.

 * Can you please let me know if you get the same error log entries from a backup
   using 1.5.4.

 * Yes, that is a message from 1.5.4. Actually this has been occurring for at least
   this most recent update and the previous one as well. I just reverted back to
   1.4.5 after trying a few backups with each release when I found the error persisted
   instead of messing with it. 1.4.5 works for me with a smaller sized backup so
   that is what I have been relying on.
 * Let me know if there is anything else I can do to help.

 * Thanks mate. I’ll investigate.
 * Apart from filling the logs the warning should not affect the normal operation
   of a backup.

 * From what I recall, the very first backup (which was manually initiated) following
   the update of the plugin to the most recent version worked normally without errors.
   It was subsequent updates that is where the errors began occurring. Not sure 
   if that helps you at all, but that was how I think it went this most recent run
   at it.
 * Thanks Mikey!

 * Gday mate,
 * After the release of 1.5 I found out that my testing servers had a WP feature
   turned on that suppressed database errors. I am not sure if this is default for
   WP but most hosts appear to opt into errors being displayed either way.
 * This is why people where seeing dupe errors that do not affect the operation 
   of a backup. I have since made a change to better insure that the value does 
   not exist before inserting ergo fixing the warning.
 * Cheers,
    Mikey
