Sent only when the operative asks. The bytes go up first through `POST /v3/uploads`, and this names that upload. Only the person who made the upload can file it: anyone else's upload id is answered as not found. The file has to be a SQLite database, which is checked against its own first bytes rather than the content type it was uploaded with. The organisation is the one the backup is filed against, and decides who can see it. The database itself is not scoped to it: a device caches data for every organisation its user belongs to, and the app says so before anything is sent. The response carries a short `reference` for the operative to read out. Backups are kept for 30 days. ## OpenAPI ````yaml /api-reference/openapi.yaml post /v3/device-backups openapi: 3.1.0 info: contact: email: support@ctrl-hub.com name: Ctrl Hub url: https://www.ctrl-hub.com description: > Ctrl Hub is the all-in-one platform for high-risk industries like utilities, construction, infrastructure, and renewables.
