Environment
- Mixed-age physical servers, several past end of support
- Backup jobs reporting success with no restore ever attempted
- Management interfaces reachable from the general user network
- No documented recovery point or recovery time objectives
Manufacturing / distribution
Virtualization consolidation with tested disaster recovery
Business applications ran on ageing physical servers of varying age, with backups that had never been restored. A hardware failure would have meant rebuilding from scratch with no confirmed recovery time.
- VMware vSphere
- Proxmox VE
- Veeam
- ZFS
Architecture
- Clustered hypervisor platform sized with N+1 headroom from measured usage
- Redundant storage paths and workload-matched performance tiers
- Separate networks for management, migration, storage and workloads
- Application-aware backups with an offsite and immutable copy
- Recovery objectives agreed per service before the design was finalised
Implementation
- Dependency mapping and measured resource profiling across a full business cycle
- Migration in waves, starting with low-risk internal workloads
- Physical sources kept recoverable until each wave was signed off
- Management plane moved onto a restricted network with role-based access
- Restore tests executed and the actual recovery time recorded per service
Outcome
- Recovery is now a rehearsed procedure with a known, documented duration
- Host maintenance happens without taking applications offline
- Capacity decisions are driven by measured data rather than server specifications
- Backup failures raise an alert to a person instead of sitting in a log
