new or changed objects are just appended to the existing file.  Anything
appended whilst copying will not be in the backup.  The backup, however,
should be fine.

Data.fs.in is an index that helps zope get started faster.  If you start
without it, then zope has to read the entire Data.fs file.  Data.fs.lock
file is the file that says that the data.fs is in use.  If you delete
this whilst running, and start zope again on the same zodb, Very Bad
Things(tm) could happen.
