He does use rysnc to do incremental backups but the issue is if you discover a file has got corrupt and it got corrupted 3 months ago (for example) so he wants to be able to go back to when it wasn't corrupt.

This will be no problem with my method. This is a snippet of my backup script

BACKUPDIR="/mnt/data/backup/"
DATE=`date +%y%m%d`

SOURCES="/boot/ /etc/ /home/ /usr/local/bin/" # !!!IMPORTANT!!! directories must end with /
RSYNC="--delete"
LASTBACKUP=`ls -d $BACKUPDIR | sort -r | grep -v lost+found | head -1 `
for SOURCE in `echo $SOURCES`
do

if [ "$LASTBACKUP" ]; then
INC="--link-dest=$LASTBACKUP$SOURCE"
fi
mkdir -p $BACKUPDIR$DATE$SOURCE # create directories without error control
rsync -avzP $RSYNC $INC $SOURCE $BACKUPDIR$DATE$SOURCE
done

You can delete any backup and still have a complete backup in any other backup folder.
