Every organization has backups. Far fewer can actually run their business from them within hours of a ransomware event, a regional outage, or a failed migration. The difference between backup and disaster recovery is the difference between owning a spare tire and knowing how to change it on the highway.
01Backup answers 'is my data safe?' — DR answers 'is my business running?'
Backup is a copy of data. Disaster Recovery as a Service (DRaaS) is a warm, orchestrated replica of your entire environment — servers, networking, and dependencies — that can be promoted to production in minutes. Organizations that conflate the two discover the gap at the worst possible moment: restoring terabytes from backup storage can take days, while contractual and regulatory obligations are measured in hours.
02RTO and RPO: the only two numbers that matter
Recovery Time Objective (how long you can be down) and Recovery Point Objective (how much data you can lose) should be set by the business, not the IT budget. A finance system might demand an RTO of one hour and RPO of five minutes; an archive server might tolerate 48 hours. Tiering workloads against honest RTO/RPO targets is what turns a DR line-item into a defensible continuity strategy — and it usually reveals that only 20–30% of workloads justify premium replication.
03Ransomware changed the calculus
Modern ransomware targets backup repositories first. Immutable storage, logically air-gapped copies, and clean-room recovery environments are now table stakes. A credible DR posture in 2026 includes verified restore testing — because an untested DR plan is a hypothesis, not a plan. Insurers increasingly ask for evidence of test results before writing or renewing cyber policies.
04The supplier landscape
The DRaaS market spans hyperscaler-native tooling, purpose-built providers, and colocation hybrids. Pricing models differ wildly — per-VM, per-TB, or reserved-compute — and the cheapest quote is rarely cheapest at declaration time. We evaluate providers against your actual RTO/RPO tiers and negotiate declaration terms before you sign, not after you need them.
Key takeaways
- Backups alone do not guarantee continuity — orchestrated recovery does
- Set RTO/RPO per workload tier; not everything deserves premium replication
- Demand immutable, air-gapped copies and scheduled restore testing
- Scrutinize declaration fees and runtime costs in every DRaaS contract
