Aura HD KoboUtilities Plugin: Database backup failure

First, my thanks to David Forrester for his outstanding plugin. :thumbsup:

I setup the plugin to backup the database upon connection and it worked but only twice. Recently, when connecting my Aura HD to Calibre the error below appears. What might be causing this? And are any subsequent manual backups good or corrupt?

Thank you.

Edit: I am also experiencing the same result with my Mini :(
