Version Management

By setting version management on a bucket, you can manage the history of file modifications when uploading files with the same name. Additionally, you can check the version list of files and download previous versions of files from the version list.

Notice
When using the version management feature, if you accidentally upload a file and overwrite an existing file, you can find the previous version through the version list.

Checking Version List

You can check and manage versions of file uploads and modifications from the time version management is set up.

Notice

  • All files have a version ID. However, before version management is set up, the version ID is null(-), and files uploaded after version management is set up are created and assigned a version ID.
    • For example, if you upload files with the same name to the same location, a new version file with a different version ID will be displayed in the version list even though the file name is the same.
