Object Storage Tiering & Lifecycle
A four-tier storage architecture with automated age-based lifecycle transitions, backup integration, and cross-region replication.
- Tiers, lowest to highest cost per GB: `nvme-hot` (active data, <5ms latency, highest cost) → `ssd-warm` (recent backups, 30–365 days, medium cost) → `sata-bulk` (compliance archives, 1–7 years, low cost) → `sata-cold` (long-term retention, lowest cost).
- Objects are created in `nvme-hot` by default; lifecycle policies transition them to colder tiers automatically as they age, based on per-DataResource lifecycle annotations.
- Velero uses a Nest object DataResource as a BackupStorageLocation target, and cross-region replication provides multi-region copies for disaster recovery.
