To reduce costs (and possibly save energy), we're experimenting with moving older files to cold storage.
For now the simplistic approach is a #Scaleway object storage lifecycle rule to move all attachments older than 180 days to the Glacier class. It's not possible for such rules to target only originals, or mp4 files, or files above a certain size.
In a few months we can consider whether to refine this approach. Feedback appreciated.
