DRaaS is disaster recovery delivered as a managed service, with a ready secondary environment to fail over to.
It suits enterprises that need tested recovery without building and running a second data center.
Self-managed DR suits large estates with the skills, scale and reasons to own it.
The honest test: a managed, tested service usually beats an owned but neglected one.
Every enterprise needs disaster recovery. Far fewer want to build and run a second data center to get it. That gap, between needing recovery and wanting to operate the infrastructure behind it, is exactly what DRaaS fills.
Here is what it is, and how to tell whether it beats building your own.
DRaaS, Disaster Recovery as a Service, is disaster recovery delivered as a managed service by a provider. Rather than building, staffing and testing your own secondary site, you replicate your workloads to the provider's environment and fail over to it when your primary site is hit by an outage, hardware failure, site loss or a cyber-attack. The provider supplies the infrastructure and the expertise; you get a recovery capability without running a second data center yourself.
Your systems are replicated to the provider's environment on an ongoing basis, so a current copy is always ready. When a disaster strikes, you invoke the service and your workloads start running in that environment, keeping the business operating while your primary site is restored. Once it is back, you fail back to it. The replication runs quietly in the background; the failover is the part you invoke only when you need it.
The difference is who builds, runs and tests the recovery environment. With self-managed DR, you own and operate your own secondary site, with full control but the full burden. With DRaaS, that burden shifts to a provider for a recurring fee. The table sets out the trade.
| Factor | Self-Managed DR | DRaaS |
|---|---|---|
| Up-front cost | High; you build the second site | Low; you subscribe |
| Ongoing burden | You maintain, staff and test it | The provider runs and tests it |
| Control | Complete | Shared with the provider |
| Expertise needed | Significant in-house DR skills | Less; the provider supplies it |
| Best for | Large estates with DR skills and reasons to own | Enterprises wanting tested recovery without running a second site |
When you need dependable recovery but do not have a fully-staffed, regularly-tested second site, which describes most enterprises. DRaaS wins when the up-front cost of building a secondary data center is hard to justify, when you lack the specialist DR skills to run one well, or when you would rather your team focus on the business than on maintaining infrastructure you hope never to use. Above all, it wins because a managed, tested service beats an owned-but-neglected one, and neglected is what many self-built DR sites quietly become.
When you have the scale, the skills and specific reasons to keep recovery entirely in-house. Large enterprises with dedicated infrastructure teams, very particular control or compliance requirements, or an existing second site they already run well, may be better served by self-managed DR. The deciding factor is not just capability but discipline: owning DR only pays off if you actually maintain and test it. If you have the team and the rigour to do that, self-managed can be the right call.
For most enterprises without a tested second site, yes. If your recovery today rests on backups you have never fully restored, or a DR plan that exists on paper more than in practice, DRaaS is likely to give you a more dependable, better-tested recovery than you have now, at a lower up-front cost. The decision comes down to whether you can realistically build and maintain your own, and for many organisations the honest answer points to a managed service.
The value of disaster recovery is realised on exactly one day, and on that day a tested, managed capability is worth far more than an owned site nobody maintained. Choosing between DRaaS and self-managed, and building either so it actually works when invoked, is where an experienced partner helps.
