-- Backups Torqvoice runs for a workshop on the cloud instance (one restic
-- repository per workshop in a bucket of ours), beside the destinations a
-- workshop connects itself. A run row now says which of the two it belongs
-- to, and a platform run has no connection. Existing rows are destination
-- runs and keep their connection.
