Beginning 1/31/14 and since, backup logs on my site have the same warning and error message. However, after the error it seems that the backup does execute a successful export to XML and generate the export file. (See log section below.) Is this the case and the export is the proper backup without error?

I was altered to the problem by a Dropbox message that my use was nearing the capacity limit. Same finding as fssbob. The update resulted in backups going to a new folder, and the old backup folder and its multiple files being included in all new backups. I followed his advice and have excluded the old folder from future backups.
