The user backup example, backupshak.sh, will not handle
correctly the case of renamed files.  This takes the form
of not backing up the file at all because the file inode is not
changed by a true move ( mv(1) ) hence mtimefilter(1) will not
pass the name out stdout to be backed up.  

One possible incomplete solution to this is to make the filter 
program (e.g. mtimefilter) echo the entire contents of a 
directory if the directory itself has a 'later than filter 
date' date.  mtimefilter(1) can be told to behave this
way by using the `-s' switch.  The programs in this directory 
as distributed do not use the `-s' switch. 

Use of the `-s' switch is recommended. see mtimefilter.1
manual page and edit backup.proper and backup.common scripts
in this directory.


The LOG*.STDERR file, by its contents, can indicate an error.
Exceptional contents will always indicate an error, though
non exceptional contents does not mean no error.
