I'm receiving the following error when I attempt to run

I'm receiving the following error when I attempt to run an immediate Snapshot backup. Would anyone know what's causing it?

ERROR: PcLZIP file:media/2013/04 add failed -10: gzip temporary file '/home/rogergeo/public_html/wp-content/uploads/snapshots/_backup/1368924105/pclzip-519856e11c47e.gz' has invalid filesize - should be minimum 18 bytes [code -10]

Thanks for any assistance.
