Starting point
Critical applications and data sat at a single site. A fire, a power failure or a hardware fault would have stopped operations — with data loss the business could not have recovered from.
What we built
Critical data and virtual servers are replicated to two sites: the primary site active, the second on standby to take over in an emergency. Recovery scenarios were designed against defined RPO and RTO targets. Backup was planned alongside for archiving, long retention and systems where a longer RPO/RTO is acceptable, scheduled to keep the load on production minimal.
Result
Critical systems keep running at the second site in an emergency. Downtime and the risk of data loss are significantly reduced, and the dependency on a single site is gone.

Central camera system with network segmentation
Security staff access the cameras they are cleared for from one place, recordings are retained correctly, and video traffic no longer loads the data network. An incident in the camera segment does not spread to other segments.
Corporate ITPhysical servers virtualised (P2V)
The hardware dependency is gone. Backup, restore, migration and resource management now run through the virtualisation layer instead of hardware appointments.
Multi-branch businessFirewall cluster with high availability
In testing the second instance took over each time and the link between head office and branches stayed stable. The dependency on a single firewall or line is gone.
