Thank you everybody !
I have been damned stupid, or tired - or both !
Actually, the file was hidden behind a mount point which failed briefly, but long enough so that a backup took place - and was dumped onto the filesystem - then the mount resumed, and hid the 10 GB backup !!!
Thanks again !

Indeed. At this point I'd start looking at things hiding under mount points.
