It means that one should not "hard-code" strings in code.
if [ -d /media/backup ]
can be rewritten as:
BACKUP_DIR=/media/backup
if [ -d $BACKUP_DIR ]
In future, if /media/backup changes, you only have to replace the
value once in the assignment (BACKUP_DIR=/media/backup), rather than
all instances where you have used them in your script.
