True.  It is much more likely that the Data.fs was replaced about a week 
ago (say an attempted backup restore) and the Zope process wasn't 
restarted.  That is one way to evoke the observed behavior.

Since this is apparently a flavor of Unix, the output of "lsof" might be 
helpful.  It should show you if you have a Zope process that is holding 
onto a deleted file.

If this is the case you'll have to get imaginative to recover the file. 
  Killing the process and immediately attempting to "undelete" it might 
work (for some file systems, apparently not ext3).
