Check FAQs first.

You can get your questions answered quickly by referring to the answers in the FAQ before reading the guide. If you haven't found the answer to your question in the FAQ below, then search the guide for what you'd like to know.

Q. How do I use Object Storage?

Q. What is the difference between Manage disclosure and Manage permissions?
A. The Manage disclosure feature is used to disclose a bucket or a file to users around the world outside of NAVER Cloud Platform.

  • Disclose bucket: anyone can view the list of objects (files/folders) in the bucket and upload a file.
  • Disclose file: anyone can open and download a file.

Manage permissions is a feature to grant buckets or files permissions to NAVER Cloud Platform users. You can optionally grant desired privileges to a specific user.

  • Permissions that can be granted in buckets: bucket list view, file upload, Access Control List (ACL) view, ACL modification
  • Permissions that can be granted in files: file download, ACL view, ACL modification

Q. If another account with the bucket usage permission uploads an object, then how can I view the uploaded object?
A. When an account holder uploads an object, the account holder becomes the owner. Therefore, the bucket owner has to receive an access permission from the object owner to view the object. You can set Object ACL with an API by referring to the Object ACL API Guide.

Q. Can I use tools that link with Amazon S3?
A. As Object Storage provides the API compatible with Amazon S3 API, you can use Object Storage based on the tool that utilizes S3.
To use S3, you have to install the S3 browser and link your account using the API authentication key. For more information, refer to API Authentication Key Creation and S3 Linkage Guide.

Q. I downloaded an object, but the actual file size is different from that displayed on the console.
A. When you view the object downloaded on your PC, the file size can be displayed differently because a file size is calculated in different ways for each OS. The actual size of the object can be viewed through content-length, and there is no error in the object.

Q. How can I access Object Storage in the VPC environment?
A. You can access Object Storage using the following methods depending on the type of subnet.

  • Server installed in a public subnet
    • Internet-based communication can be conducted using kr.object.ncloudstorage.com, a public domain.
    • Private communication can be conducted using kr.object.private.ncloudstorage.com, a private domain.
  • Server installed in a private subnet
    • By default, private communication can be conducted using kr.object.private.ncloudstorage.com, a private domain.
