Lifecycle Config
A lifecycle config automatically manages the lifecycle of objects, for example moving them to a different storage class or deleting them after a period of time. Like the Bucket Policy tab, this is a raw JSON editor, not a multi-field form.

Apply templates
The Áp dụng templates (Apply templates) dropdown offers a couple of ready-made templates, for example:
- Delete files older than 7 days
- Delete files from failed multipart uploads after 7 days

Picking a template overwrites the JSON box right away; click Cập nhật (Update) to actually save it.
Action buttons
- Format JSON — reformats the JSON for readability.
- Cập nhật (Update) — saves the lifecycle config to the bucket.
- Xoá (Delete) — removes the current lifecycle config entirely.
Delete uses the browser's native confirm dialog
Unlike most other delete actions in Simple Storage, clicking Xoá (Delete) here opens the browser's native confirm() popup (not a portal UI dialog) reading "Xoá lifecycle config?" (Delete lifecycle config?). If your browser blocks this popup, the delete action won't go through.
