No fee · the whole market competes

DRaaS replicates your critical systems to a provider's cloud and fails them over automatically or on-demand when disaster strikes — ransomware, site outage, human error. It replaced the old "second data center nobody tested" model with contractually defined RPO/RTO.

The providers below are the ones we deploy most: many are colocation platforms with strong managed-DR practices — because DR quality is mostly about the people testing and running it, not the software.

Frequently asked questions

How much does DRaaS cost?

Typically $100–500 per protected workload tier monthly depending on data volume, RPO/RTO targets and whether failover capacity is reserved. Contracts define recovery commitments — read the RPO/RTO language hardest.

What's a good RPO/RTO for a mid-market business?

Most of our clients land at RPO ≤ 1 hour (near-real-time replication) and RTO ≤ 4 hours for tier-1 systems. Anything tighter costs real money — classify applications first.

Does DRaaS protect against ransomware?

Yes when designed for it — immutable snapshots, isolated recovery environments and tested runbooks. Ask specifically how the provider prevents replication of encrypted/infected backups.
