Decision guide · Business continuity
How should I design infrastructure for business continuity?
First identify critical processes and impact, then define RPO, RTO, dependencies, owners and failure scenarios. That baseline determines the right combination of redundancy, backups, alternate site, connectivity, monitoring, security and recovery procedures. ZGH can provide infrastructure, network and operations, while the outcome requires agreements and tests with the customer.
Use cases
Where this framework is a priority
Services that cannot stop
ERP, commerce, healthcare, security, public platforms and processes with financial or operational impact.
Concentrated dependencies
Operations where power, connectivity, hardware, people or suppliers are a single point of failure.
Growth without architecture
Systems that expanded in capacity and complexity without updating backup, monitoring or recovery.
Decision criteria
From business impact to architecture
Technology is selected after understanding what must recover, in which order and with which information.
-
Critical services
Processes, users, schedules, impact and recovery order.
-
RPO and RTO
Tolerable data loss and target time to resume operations.
-
Dependencies
People, suppliers, DNS, network, identity, licenses, applications, data and access.
-
Controls
Redundancy, backup, replication, monitoring, security and documentation.
-
Testing
Restorations, exercises, results, gaps and owners for corrective action.
Explicit scope
Deliverables for an operable strategy
Design and document
- Service and dependency map
- RPO and RTO per service
- Target architecture
- Responsibility matrix
- Recovery procedures
- Test and improvement plan
Do not confuse with complete continuity
- RAID does not replace backup
- Untested backups do not prove recovery
- Local high availability is not geographic DR
- Monitoring does not imply authorized response
- A second link may share physical risks
- SLA must match the contracted architecture

FAQ
Business continuity questions
Does RAID mean I have a backup?
No. RAID helps with certain disk failures but does not by itself protect against deletion, corruption, malware or loss of the site.
Does a backup guarantee recovery?
Only a tested restoration shows that data and procedure can recover the service within the objective.
Do I need a second data center?
It depends on impact, RPO, RTO and the risks you need to cover. Not every service requires the same geographic separation.

Start from impact, not from a product
Share critical services, dependencies, tolerable data loss and maximum recovery time. We will design alternatives and state their limits explicitly.
