Differences vs Huawei
- Capability scope differs: DataSync supports file and object endpoints with agent-based and managed transfer paths, while OMS focuses on object-storage migration to OBS.
- Pricing model differs: DataSync bills by transferred data volume (plus related storage/network costs), while OMS billing emphasizes migrated-data volume/API requests and source-side network egress.
Migration to Huawei
- Map data durability tier, lifecycle policy, encryption, retention, and restore objectives. For AWS AWS DataSync, the direct Huawei equivalence layer is OMS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
- Use a composed Huawei migration pattern where needed: OMS + OBS + MGC. Treat OMS as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
- Pricing model difference: AWS usually bills GB-month capacity, request operations, retrieval, and transfer; Huawei usually bills OBS/EVS/SFS/CBR capacity, requests, retrieval/replication, and transfer. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
