There may be old unfinished rollups jobs (status != "data_export_finished")

It can happen if there is unfinished rollup older than the retention date.

The rollups are running based on

SELECT tenant_id
FROM tenants
WHERE refresh_rollups = True

So if record in tenants have refresh_rollups == False and there is some unfinished record in "rollups_jobs" table and there are no new tarballs, it could happen

It prevents Data pruning from deleting
