backup_list_unavailable

HTTP 503 The list of backups cannot be read completely right now

What happened

The backup list is read from storage on every request, and this time the scan either failed or did not finish in time. You get an error instead of a shortened list, because a backup missing from a response reads as a deleted one.

What to do

Retry in a few seconds; if the response carries a Retry-After header, wait at least that long. Until a request succeeds, do not treat an older list as the current state.

Retrying

The request itself is fine. Repeat it later; after a 5xx use a new idempotency key and read the resource first.
