Case Study: IAK (Danish Unemployment Fund) achieves 28-hour weekly backup time savings with Veeam Backup & Replication

Danish Unemployment Fund Saves 28 Hours Each Week on Backups of Virtualized Machines

IAK is a Copenhagen-based unemployment insurance fund for 70,000 engineers with about 100 employees and a fully virtualized IT center (40 VMs). Their previous backup solution became unreliable after an upgrade, forcing weekly full backups of ~900 GB that took ~20 hours and frequently failed, leading to an additional 5–8 hours of troubleshooting and network slowdowns that impacted users. They needed a stable, dependable backup approach for their virtual environment.

IAK deployed Veeam Backup & Replication (with help from N2IT), using one initial full backup then incremental synthetic and reverse-increment backups plus deduplication and VMware vSphere/vStorage API support. The change cut backup and recovery overhead by up to 28 hours per week, reduced 14-day rollback storage from ~1 TB to ~0.5 TB, delivered consistent restore performance, and made WAN synchronization of backup files practical.
