Single service comparison

AWS Backup abstracts many resource types (EBS, EC2, RDS, DynamoDB, EFS, FSx, S3, Storage Gateway) behind one vault and plan API, with tag-based assignment and AWS Organizations integration for cross-account backup. Huawei splits the equivalent across CBR vaults by resource class (server, disk, SFS Turbo, file) plus dedicated database/desktop backups; CBR server backup (the successor to the legacy CSBS product) covers ECS/HECS/BMS but does not unify S3-class object or NoSQL store backup. Expect a less declarative, more resource-typed control plane and no native Organization-level policy inheritance.

AWS Backup offers backup vault lock (WORM), continuous backup and PITR for supported resources, separate cold-storage lifecycle tiers, and Backup Audit Manager via CloudTrail. Huawei CBR provides vault backup locking, cross-region replication, incremental backup and Instant Restore with minute-level RTO, ransomware protection integrated with HSS, and application-consistent backup via custom scripts for MySQL/Linux apps; however, PITR is not a general CBR feature, lifecycle tiering to cold storage is limited, and cross-account backup is not a documented capability. Architects must rebuild governance around IAM and CTS rather than AWS-style Organizations backup policies.

Scaling and operational responsibility differ: AWS Backup is serverless with throughput governed by assigned backup vault settings and service quotas, while CBR backup performance is tied to vault capacity, EVS/SFS underlying throughput, and snapshot limits per resource. Cross-region copy on AWS is a vault copy job; on Huawei it is CBR cross-region replication configured at the vault. Restore on both is resource-native, but Huawei's restore-to-new-server and image-from-backup paths lean on IMS, and restore scope is bounded by the vault's resource type rather than a single cross-resource restore API.

Inventory every AWS Backup plan, vault, resource assignment, retention rule, copy destination, encryption context, and legal hold, then map each protected resource to a Huawei CBR vault type: ECS/HECS/BMS to a server backup vault (CBR's successor to the standalone CSBS product), EBS-equivalent EVS to a disk backup vault, EFS/FSx-equivalent SFS Turbo to an SFS Turbo backup vault, and managed databases to their native backup or GaussDB/RDS backup. Do not assume a one-to-one plan transfer; CBR assigns policies to vaults and resources individually, so re-express tag-based selection as explicit vault membership and per-resource policies.

Rebuild retention and copy policies using CBR scheduled/periodic backup policies with min retention floors, and replace AWS cross-region copy and vault lock with CBR cross-region replication plus vault backup locking where WORM behavior is required. Validate application-consistent backup with CBR's custom pre/post-freeze scripts for MySQL and Linux workloads, since AWS Backup's native app-consistency for VSS-aware resources has no blanket Huawei counterpart. Encryption moves from AWS KMS to Huawei KMS-backed vault encryption, and access control from IAM backup policies to IAM/agency scoped to CBR.

For data movement there is no direct AWS-to-Huawei backup conversion; recreate protection in CBR by provisioning vaults sized to current used capacity (GB-month billing), attaching resources, taking a full CBR backup, and running replication to the target region. For workloads needing an alternate path, combine CBR server backup with image creation via IMS for cross-region server rebuild, and treat CSBS only as the legacy name for the server backup vault now delivered under CBR. Re-test restore to new resources and recovery drills following CBR's periodic recovery-drill best practice before declaring parity.

Recalculate TCO because billing differs materially: AWS Backup charges backup storage by GB-month, restore/job processing, and cross-region data transfer, while Huawei CBR charges vault capacity (GB-month at rates that differ by vault type), backup requests, replication traffic, and underlying EVS/OBS where used. Confirm regional availability, vault quotas, and per-resource snapshot limits for each target region, and document gaps such as limited cold-tier lifecycle, no general PITR, no native cross-account backup, and reduced unified-panel breadth versus AWS Backup.
