Best High Availability Cluster Solutions

When an emergency or disaster strikes, role swap to your on-premise or cloud backup server so your business can continue within minutes. Use your secondary system to perform nightly backups, queries, and planned maintenance activities without impacting your production system. Replicate all of production or only select libraries and programs. Your data is available on your target server instantly. Using remote journaling and a high-speed apply routine, Robot HA can replicate 188 million journal transactions per hour across any distance—physical or virtual—and apply the data the moment it is received, which means that your hot backup is always a real-time copy of production. Get peace of mind by confirming that you are ready to role swap at any moment. Manually trigger a role swap audit as needed or set it up to run at regular intervals. You can configure the audit to examine the objects that are most important to your data center.
