AWS Backup is a strong service for protecting AWS resources. Its scope is AWS. If your recovery plan requires restoring outside AWS — into Azure, Google Cloud or OCI — that is the boundary where a multi-cloud platform becomes necessary. This page compares the two honestly, including where AWS Backup is the better answer.
When AWS Backup is the right choice
If your estate is entirely on AWS, and your recovery requirements are satisfied by restoring within AWS, AWS Backup is well integrated, first-party, and requires no additional vendor. It is centrally managed, policy-driven, and supports cross-region and cross-account copies. For single-cloud organisations, it is often sufficient and we would say so.
Where the boundary sits
Scope is AWS-only
AWS Backup protects AWS resources. It does not back up or restore resources belonging to other cloud providers, which is a limiting factor for hybrid and multi-cloud architectures. If a requirement is “recover this workload somewhere that is not AWS”, that requirement falls outside the service.
Cross-account and cross-region are not always a single step
Certain services cannot be copied cross-Region and cross-account in one action. Amazon RDS, Aurora, DocumentDB and Neptune require a two-step process: copy to the destination account in the same region first, then copy to the final region. Cross-account backup is also not supported for Amazon DynamoDB tables or Amazon FSx file systems.
Cross-region settings are vault-scoped
Cross-region copy is configured at the backup vault level. Where different resources need different cross-region behaviour, that means multiple vaults, and the operational complexity that comes with them.
What CloudRebuild adds
| Capability | AWS Backup | CloudRebuild |
|---|---|---|
| Protects AWS resources | Yes, first-party | Yes |
| Protects Azure, GCP, OCI | Out of scope | Yes |
| Restore into a different cloud | Out of scope | Yes, any supported pair |
| Dependency-ordered restore | Per-resource model | Graph captured at backup, drives restore order |
| Pre-restore compatibility report | — | Typed findings, severity-rated, reviewed before execution |
| Microsoft 365 / Google Workspace / Intune | Out of scope | Dedicated SaaS engine |
The honest summary
This is not a question of which tool is better built. AWS Backup does what it is scoped to do, and does it inside AWS with first-party integration nobody else can match. The question is whether your recovery requirements stop at the AWS boundary.
They usually stop there until something forces the issue: a region-wide event, an acquisition that brings a second cloud, a contract renegotiation, or a regulator asking whether you could actually exit. At that point the constraint is not the quality of the backup — it is that the recovery point cannot leave.
Common questions
Can I run both?
Yes, and many organisations do. AWS Backup for in-AWS operational recovery, CloudRebuild for the cross-cloud and SaaS layer. They are not mutually exclusive.
Does CloudRebuild replace native snapshots?
It does not have to. Native snapshots are excellent for fast, same-cloud, same-account rollback. CloudRebuild addresses recovery that has to cross a boundary — account, region, provider, or all three.
What about egress costs on a cross-cloud restore?
Cloud providers charge their own egress fees when data leaves their network. We identify those in your quote rather than leaving them as a surprise. See pricing.
