[Book a demo](https://bus4i.com/contact-us/) [View products](#products) The risk ## What happens when your IBM i goes down? A hardware fault, a failed update, a fire in the data center: your IBM i rarely fails. But when it does, order entry, warehouse and accounting all stop at once. Data entered since the last backup is often lost. And many companies only find out how long a restart really takes when it happens. With BUS4i, you know beforehand. You choose the protection that matches your risk and your budget. ![Burning IBM server in a data center](/_astro/server-outage.CRHfPaph_ZODvLB.webp) Business case ## What does downtime cost you? Besides the loss of trust and reputation, every hour without your system has a price in euros. With BUS4i, your restart time can be planned precisely. [Plan your restart time](https://bus4i.com/contact-us/) - **Downtime**Upgrades, nightly backups or an outage bring your business-critical applications to a standstill. - **Data loss**Online orders or EDI orders placed between two backups often cannot be reconstructed. - **Compliance**Standards such as ISO 27001 or NIS2 require a reliable and traceable IT infrastructure. How BUS4i protects you ## One principle, three targets: every change transferred in real time BUS4i captures every change on your IBM i – formerly AS/400 or iSeries – immediately and transfers it to a second target. You decide where it goes. ### To a secondary system If your primary system fails, the secondary system takes over. Your applications keep running. [High availability for IBM i with BUS4i HA](https://bus4i.com/bus4i-ha/) ### To network storage You don’t lose a single transaction between two backups – without a second IBM Power machine. [Disaster recovery with BUS4i DR](https://bus4i.com/bus4i-dr-for-ibm-power-i/) ### To your new system You move to new hardware while your operations keep running. [Migration during live operation with BUS4i Migrate While Active](https://bus4i.com/bus4i-migrate-while-active/) The BUS4i product family ## You have the choice From disaster recovery to full high availability, from migration to journal management. High availability ### BUS4i HA Real-time mirroring between primary and secondary systems, combined with automatic switch-over to redundant systems, keeps business-critical applications running.

That depends on how long your business can afford to stand still. If it must not go down at all, [BUS4i HA](https://bus4i.com/bus4i-ha/) mirrors your system to a second IBM Power system that takes over immediately. If you want to lose no data but do not want to run a second machine, [BUS4i DR](https://bus4i.com/bus4i-dr-for-ibm-power-i/) saves every change in real time to network storage. For moving to new hardware, there are [BUS4i Migrate 23](https://bus4i.com/bus4i-system-copy-migrate-23-for-ibm-power-i/) and [BUS4i Migrate While Active](https://bus4i.com/bus4i-migrate-while-active/).
