详细信息
Returns a presigned URL the customer's browser fetches **directly from object storage**; the archive never passes through the control plane. A site archive is measured in gigabytes, so proxying it would make the customer's site size our memory ceiling and hold a request thread for the length of the transfer. ⛔ **`POST`, despite reading nothing.** The response body is a bearer credential for the whole site — database included — so a `GET` would invite it into browser history, proxy logs and shared caches, and the audit row this writes would be created by every prefetch. The grant expires; take a new one rather than storing it. A backup that never produced a stored archive is `422` (`backup_not_downloadable`) rather than a signature over a key that is not there, which object storage would reject seconds later as an opaque `404`. Requires `hosting.backup.export` — or `hosting.backup.manage`, which every holder of the old gate still has — and never `sites.view`: reading a tenant's database out is never a viewer's. A per-site *editor* holds `hosting.backup.export`, which is how `zinnector pull` brings the files down for local development without being able to restore.
参数
| 名称 | 类型 | 必填 | 内容简介 |
|---|---|---|---|
siteId (path) | Uuid | 是 | Site ID (UUIDv7). |
backupId (path) | Uuid | 是 | The backup's id (UUIDv7), as `getSiteBackups` reports it. **Ours**, minted when the row was written — never the storage key, which is an internal object path and is deliberately… |
响应
| 名称 | 类型 | 必填 | 内容简介 |
|---|---|---|---|
url | string | 是 | The presigned object-storage URL to fetch the archive from. Hand it straight to the customer's browser and let it expire; take a fresh grant rather than caching this one. |
expires_at | string | 是 | When the signature stops working. A download that has already started is unaffected; a new one after this moment is refused by storage. |
size_bytes | integer | 是 | The archive's size, as object storage reported it when the backup was stored — so a client can warn before a multi-gigabyte download. |
etag | string | 是 | The stored object's entity tag, for a client that wants to verify the bytes it received are the bytes we hold. Empty when the backend did not report one. |
