I wouldn't dismiss what Marc was onto. If you do the math, 44G in /documents + 11G in the rest of / == 55G, seems to be a bit more than
coincidence. I know you already tried ls -l /documents/ after you
umounted but just for curiosity's sake, I wonder what happens when you do:

umount /documents
du -sh /documents

du -sh /documents/
4.0K    /documents/

I agree with you about 44+11.  The mystery if this is the origin of my
problem, is that we are talking about two separate drives (/dev/hdb1 +
/dev/hda1).

What is the result of

  umount /documents
  umount /maxtor
  du -x --max-depth=1 / | sort -n

Very interesting!

So...there is a copy of many OLD faubackups on /dev/hda1!

My backup strategy involves two Maxtor external hard drives, one being
connected for six months and then swapped with the second which has been
stored off site.  Somehow the non-connected Maxtor data has been saved
on /dev/hda1.

My easy solution is to umount /maxtor, and delete all the old backups.

I wonder, maybe faubackup can't cope with disappearing data...?

Thanks for any input.

Maybe it is due to the way faubackup works. In the man pages it states :


   BUGS

You need a filesystem with stable device id and inode number so that faubackup can correctly find your files again. This may be violated by some remote filesystems, for example Samba.


Maybe swapping drives falls into this categorie too.
