Backup not complete again

Well the backup will run on schedule even if no files change. Any new file, or file with a new size or date should be copied. I'd edit the backup job and change from NFS to rsync once you get the initial files copied.

The backup of the iso files completed in good order.
I copied the ~1200 small files back and started the frontend backup job again. It ran for a bit and completed. I checked the directory listings against each other and not all of the files copied over.
There are 606 *.metathumb files and 388 copied over.
There are 607 *.xml files and 431 copied over.
I switched the backup job to remote: Rsync Server. It ran quickly and did not change any results. I moved the metathumb out, ran the backup again, results did not change.
One of the files that did not copy was XX_2013.metathumb. So I copied and pasted it back with Win7 to add a file XX - Copy.metathumb to the source folder. The remote: Rsync Server backup job did not pickup the change and did not copy the new file. That is in addition to the other files it will not copy (see above). I added another file XXX_2008 - Copy.metathumb, the original file did copy to the backup folder. The new XXX_2008 - Copy.metathumb file was not copied
The remote: Rsync Server backup job has some blind spots. I deleted the *.metathumb and *.xml files from the RN104 and ran the remote: Rsync Server backup job again. It did not notice the files were missing from the backup folder.
