Disaster recovery with RTO/RPO targets, failover runbooks, and quarterly DR drills — because a runbook you've never tested is theater.
Talk to a DR specialistMost companies have a DR plan on paper and zero confidence it will work. The runbook was written 3 years ago, the contacts are out of date, the failover procedure was never tested, and the last 'DR drill' was a checklist review in a conference room. When a real disaster hits, they discover the runbook doesn't work and the team doesn't know what to do.
CB4UHost's DRaaS is built around tested failover. We design the DR topology (warm standby, pilot light, or backup-only based on your RTO/RPO), write the runbook, and run quarterly DR drills where we actually fail over to the DR site, verify the system works, and fail back. We find issues during drills — not during outages.
We're vendor-neutral on the DR site. AWS, Azure, GCP, a different region of the same provider, a different provider entirely, or your own datacenter — the right choice depends on your RTO/RPO, budget, and risk tolerance.
Every engagement ends with a tested runbook, drill reports, and a 30-minute executive summary of what worked and what didn't.
We work with you to define RTO/RPO targets per workload — based on business impact, not gut feel.
Warm standby, pilot light, or backup-only — chosen per workload based on RTO/RPO and budget.
Step-by-step failover runbook with contacts, prerequisites, and verification steps.
We actually fail over to DR, verify the system, and fail back — every quarter.
What worked, what didn't, what we fixed — so the next drill is better.
We update the runbook, fix issues found in drills, and improve RTO/RPO over time.
We define RTO/RPO targets per workload based on business impact.
We design the DR topology and build the failover runbook.
We run the first DR drill and fix any issues.
We run drills every quarter and improve the runbook.
We report DR readiness to executives — 'we can recover in X hours, proven by drill on date Y.'
Warm standby = full replica running in DR region (low RTO, high cost). Pilot light = minimal replica running, scales up on failover (medium RTO, medium cost). Backup-only = just backups, restore on failover (high RTO, low cost). We recommend per workload.
Quarterly for mission-critical workloads, semi-annually for standard workloads, annually for low-priority. Drills are the only way to know the runbook works.
We don't fail back — we fix the issue, retry the drill, and only fail back when the drill succeeds. A failed drill is a successful finding — better to find issues during a drill than during an outage.
Yes — multi-region within a cloud provider is the simplest DR setup. We also do cross-cloud DR (AWS → Azure, etc.) for clients who want protection against provider outages.
24×7 NOC for AWS, Azure, GCP, and OVHcloud — monitoring, patching, backups, security hardening, and cost optimization. Per-service pricing.
DBA-as-a-service for MySQL, Postgres, SQL Server, MongoDB, and Redis — schema review, query tuning, backups, replication, and 24×7 monitoring.
Design hybrid topologies that put latency-sensitive workloads on dedicated hardware and burstable workloads on cloud — with secure networking between them.
