Managed Object Storage Versus Self-Hosting for Marketplace Backup Retention

The article argues that a managed object-storage bucket is usually the safer choice for a beginner marketplace retaining signed documents, unless a team already runs redundant infrastructure, offsite copies, monitoring, and restore drills. It emphasizes that storage is only one part of the problem, since backups must also reflect a consistent application state and respect deletion deadlines. Recommended practice includes tagging each backup run with an immutable identifier, recording a manifest of documents with checksums and deadlines, and writing a completion record only after readback succeeds. A deletion worker can then remove expired copies while keeping a minimal audit trail. The author also cautions that self-hosted storage shifts responsibility for capacity, replication, access control, and offsite copies onto the team.
