Answer 1

With your configuration, nginx is trying to locate /home/app/public/backup/backup path, hence 404.
These 3 solutions will work for you
# remove root directive (recommended in your case)
location /backup {
autoindex on;
index index.html;
#root /home/app/public/backup;
}
# set root to public (redundant since already done)
location /backup {
autoindex on;
index index.html;
root /home/app/public;
}
# replace root with alias
location /backup {
autoindex on;
index index.html;
alias /home/app/public/backup/;
}
For more information check how root and alias work, you can also read how nginx handles user requests
