# DELETE /storage/upgrade-backups/{id}

`DELETE /storage/upgrade-backups/{id}`

## Request

- The document declares no server URL.
- Auth: one of:
  - API key in query parameter `auth`
  - API key in header `Authorization`

Deletes one completed pre-upgrade backup after explicit confirmation.

## Path parameters

- `id` string, required

## Request body

- DeleteUpgradeBackupRequest: Request payload for deleting a pre-upgrade backup.
  - `confirmed` boolean, required

## Response `200`

Upgrade backup deleted

- DeleteUpgradeBackupEnvelope: Canonical success envelope: `{ "data": T, "ts": <unix millis i64> }`. `ts` is `chrono::Utc::now().timestamp_millis()`, set in the webserver handler via [`ApiEnvelope::now`] (the contract carries only the type + the clock helper, not a hard dependency on when the handler reads the clock). `rename_all = "camelCase"` is a no-op for the single-word fields here but is declared for forward-compat. IMPORTANT (utoipa v4): every concrete `ApiEnvelope<X>` that needs a named OpenAPI component is declared in the `#[aliases(...)]` block below. Add a new alias line whenever a new payload type needs enveloping. NEVER register the bare `ApiEnvelope` in `components(schemas(...))` — utoipa errors on a bare generic, and an un-aliased generic inlines an anonymous schema.
  - `data` DeleteUpgradeBackupResponse, required: Response payload after deleting a pre-upgrade backup.
    - `id` string, required
  - `ts` integer, required: Server time when the response was built (unix epoch milliseconds).

## Other responses

- `400`: Confirmation missing or false, or invalid backup identifier
- `404`: Upgrade backup not found
- `500`: Internal server error
- `503`: Upgrade backup storage unavailable
