Amazon S3 Glacier
Umbrella term for S3's low-cost archival storage classes (Instant/Flexible Retrieval, Deep Archive), set as a storage class on an object rather than a separate service. Most-used open-source equivalent is MinIO (S3-API-compatible object storage) paired with its own tiering/lifecycle policies to cold storage backends; for true offline archival, self-managed tape backup via Bacula remains the closest match to Glacier's retrieval-latency/cost tradeoff.
