The server already retries a failed backup on its own, up to 3 times, within 24 hours of its creation, so a manual retry is rarely needed within that time. Follow the retried backups with "List backups" (`filter[id][]`) and read `phase`. The work finishes later: see [Writes and asynchronous operations](https://api.docs.modulards.com/writes-and-asynchronous-operations). Backups that cannot be retried are reported in `meta.skipped`, each with a `reason_code` and a message, and do not fail the call: `UNSUPPORTED` (the backup is not in phase `failed`), `SITE_UNREACHABLE` (website not connected), `CONFLICT` (another backup or a restoration is running on that website) and `PERMISSION_DENIED` (a backup your token cannot reach). **Body** - `backups` (array of integers, required): ids of the backups to retry, 1 to 50, from "List backups" with `filter[phase][]=failed`. **Errors** - **409**: the storage quota is exhausted and no overage add-on is active. Nothing is retried. - **422**: `backups` is missing, empty, has more than 50 ids or contains an id that is not a backup.

A failed or stalled backup is retried automatically, up to 3 times (4 attempts in all), within 24 hours of its creation; after that it stays failed and reads 4. - `backup_type` (enum, optional) — full or incremental. - Allowed values: `full`, `incremental` - `comment` (string, optional, nullable) — Note written on the backup. - `created_at` (string, optional) - `is_favorite` (boolean, optional) — True for a master backup, kept out of the retention policy. - `method` (enum, optional) — How the backup started: manual, or automatic for scheduled ones. force_first is the first automatic backup of a website. - Allowed values: `manual`, `automatic`, `force_first` - `phase` (enum, optional) — State to read: in_progress while it runs, done for a usable backup, failed when it did not complete. - Allowed values: `in_progress`, `done`, `failed`, `excluded` - `restored_at` (datetime, optional, nullable) — When the backup was last restored; null if it never was. - `site_id` (integer, optional) — Id of the website the backup belongs to. - `size` (integer, optional) — Size of the backup, in bytes. - `status` (string, optional) — Raw processing step behind phase. - `updated_at` (string, optional) ### ApiPublicV1SiteBackupsRetryPostResponsesContentApplicationJsonSchemaDataItemsLinks - `self` (string, optional) ### ApiPublicV1SiteBackupsRetryPostResponsesContentApplicationJsonSchemaMetaSkippedItems - `backup_id` (integer, optional, nullable) — Id of the backup that was not retried. - `message` (string, optional) — Human-readable explanation. - `reason_code` (enum, optional) — Why it was refused: UNSUPPORTED, SITE_UNREACHABLE, CONFLICT or PERMISSION_DENIED. - Allowed values: `UNSUPPORTED`, `SITE_UNREACHABLE`, `CONFLICT`, `PERMISSION_DENIED` - `site_id` (integer, optional) — Id of a website that was refused. - `site_name` (string, optional, nullable) — Name of that website; null when the id is outside your token's reach. ## Examples ### 202 Accepted - one copy re-queued, one skipped **Response** ```json { "data": [ { "attributes": { "attempts": 1, "backup_type": "full", "comment": null, "created_at": "2026-09-14T15:00:00.000000Z", "is_favorite": false, "method": "manual", "phase": "failed", "restored_at": null, "site_id": 12, "size": 0, "status": "failed", "updated_at": "2026-09-14T16:05:00.000000Z" }, "id": "9001", "links": { "self": "{{base_url}}/api/public/v1/site-backups/9001" }, "type": "site-backups" } ], "jsonapi": { "version": "1.1" }, "meta": { "skipped": [ { "backup_id": 9002, "message": "Only a failed backup can be retried.", "reason_code": "UNSUPPORTED", "site_id": 12, "site_name": "Shop" } ] } } ``` **SDK Code** ```python 202 Accepted - one copy re-queued, one skipped import requests url = "https://api.modulards.com/api/public/v1/site-backups/retry" headers = {"Authorization": "Bearer "} response = requests.post(url, headers=headers) print(response.json()) ``` ```javascript 202 Accepted - one copy re-queued, one skipped const url = 'https://api.modulards.com/api/public/v1/site-backups/retry';
