Two big problems I see. (1) You don't do anything if /home/backup
_does_ exist. (2) You never set $user. Is this what you mean?

#!/bin/sh

if [ ! cd /home/backup ]; then
    echo "Cannot change to backup directory. Exiting." >&2
    exit 1
fi

# Rotate previous backups
mv $USER.0.tar.gz $USER.1.tar.gz
mv $USER.1.tar.gz $USER.2.tar.gz

# Make the new one
tar czf $USER.0.tar.gz -C $HOME .

# Done
exit 0

#End
