Solution
Backup & Disaster Recovery
Backup topologies built around stated RPO and RTO targets, with immutable copies, offsite replication and tested restores.

Scope
What is engineered
- RPO / RTO definition and job design
- Immutable and offsite copies
- Application-aware backup
- Documented restore testing
Architecture
Backup and recovery topology
Built backwards from the recovery target: what must be restored, how fast, and how much data loss is tolerable.
01 · Protected workloads
Virtual machinesFile serversDatabasesMailboxesApplication-aware processing so restores are consistent, not just copied.
02 · Backup control
Job design mapped to defined RPO and RTO per workload class.
03 · Copies
3-2-1 with immutability so ransomware cannot delete the recovery point.
04 · Verification
Restore testsRecovery runbookReportingA backup is only real once a restore has been performed and documented.
Method
Delivery sequence for this solution
- 01
Discover
Inventory the current environment, measure real usage and record constraints, dependencies and risk.
- 02
Design
Produce a topology, sizing model, addressing plan and security model before anything is procured.
- 03
Deploy
Build in a controlled sequence with change windows, coexistence and a defined rollback point.
- 04
Harden
Apply baselines, encryption, segmentation, abuse controls and least-privilege administrative access.
- 05
Validate
Test against the design: failover, call quality, restore, load behaviour and access control.
- 06
Support
Hand over documentation and runbooks, then maintain patching, monitoring and capacity over time.
Security Posture
Hardening applied at every layer
Firewall
Default-deny rule base, segmentation between voice, server and user zones, logging to a retained destination.
VPN / Secure Access
MFA on administrative access, per-role routing, short-lived credentials and revocation procedure.
PBX / Cloud / Virtualization
Hardened baselines, TLS/SRTP for voice, patch cadence, isolated management network and least-privilege service accounts.
Applications
Identity governance, conditional access, scoped chatbot tools, approved knowledge boundaries, privacy controls, staged mail authentication and audited administrative roles.

FAQ
Backup & Disaster Recovery questions
- What are RPO and RTO?
- RPO is how much data you can afford to lose; RTO is how long you can afford to be down. Both are agreed before job design begins.
- Are snapshots enough?
- No. Snapshots live on the same platform as the data. A separate, ideally immutable, copy is required to survive corruption or ransomware.
- How often are restores tested?
- On an agreed schedule, with results documented. Untested backups are treated as unverified.
