Perhaps my 2 plugins for raqbackup can also be of use for anyone. These 
plugins (to be placed in the plugin directory of raqbackup) rotate 7 
days of backups, and saving only modified files. Files in the backup 
that are not modified are being saved as a link.

In both plugins, you might want to edit the path to WORKDIR

------start.sh------
#!/bin/sh

WORKDIR=/home/raqbackup/data
TOBEREMOVED="$WORKDIR-$(date --date='7 days ago' +%F-%A)"
rm -rf $TOBEREMOVED
------start.sh------

------end.sh------
#!/bin/sh

WORKDIR=/home/raqbackup/data
TODAY="$WORKDIR-$(date +%F-%A)"
YESTERDAY="$WORKDIR-$(date --date='yesterday' +%F-%A)"

mv $WORKDIR $TODAY

for myfile in $YESTERDAY/*
do
   cmp $TODAY/${myfile##*/} $YESTERDAY/${myfile##*/} &> /dev/null
   if [ $? -eq 0 ]         # Test exit status of "cmp" command.
   then
     ln -s -f $TODAY/${myfile##*/} $YESTERDAY/${myfile##*/}
   fi
done
------end.sh------

Kind regards
