This article explains how to implement quickly a Siveillance cluster with real-time replication and automatic failover of the management services and the SQL database. Management services and SQL can be split on several clusters. ### Recorder redundancy * Replication of recorders is not suitable for SafeKit due to the volume of data. * The solution integrated into Siemens VMS can be used (failover recording server without real-time replication). * Two recorders can also run in an active/active configuration and the cameras are distributed so as not to lose all the cameras in the same area in the event of a failure. * The stream from each camera can also be sent to two recorders with the [Vega / RMF](https://vega25.com/) solution. ### A generic product Note that SafeKit is a generic product on Windows and Linux. You can implement with the SafeKit product real-time replication and failover of any file directory and service, database, complete Hyper-V or KVM virtual machines, Docker, Podman, K3S, Cloud applications ([see the module list](#modules)). ### A complete solution SafeKit solves: * hardware failures (20% of problems), including the complete failure of a computer room, * software failures (40% of problems), including restart of critical processes, * and human errors (40% of problems) thanks to its ease of use via its web console. ## SafeKit quick installation guide with Siemens Siveillance VMS and SQL (SiveillanceVMS.safe mirror module) **Download the SiveillanceVMS.safe module and go the [Milestone installation](https://safekit.evidian.com/products/high-availability-software-for-application-clustering/milestone-xprotect-corporate-high-availability-synchronous-replication-failover/#trial) replacing milestone.safe by SiveillanceVMS.safe in the instructions.** [Siemens Siveillance VMS module >](/wp-content/uploads/downloads_safekit/version-82/modules_windows/SiveillanceVMS.safe) [🧑 Contact us](https://safekit.evidian.com/products/high-availability-software-for-application-clustering/contact-us-for-safekit/) [🎁 SafeKit free trial](https://safekit.evidian.com/products/high-availability-software-for-application-clustering/safekit-free-trial/) [🏅 Free certification](https://training.my.evidian.com/mod/page/view.php?id=712) [💰 Perpetual license cost](https://safekit.evidian.com/products/high-availability-software-for-application-clustering/get-a-quote-safekit-en/) ## How the SafeKit mirror cluster works with Siemens Siveillance VMS and SQL? ### Step 1. Real-time replication Server 1 (PRIM) runs the Siemens Siveillance VMS and SQL application. Clients are connected to a [virtual IP address](https://safekit.evidian.com/products/high-availability-software-for-application-clustering/how-a-virtual-ip-address-works/#mirror). SafeKit replicates in real time modifications made inside files through the network. ![File replication at byte level in a mirror Siemens Siveillance VMS and SQL cluster](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20300%20169'%3E%3C/svg%3E)![File replication at byte level in a mirror Siemens Siveillance VMS and SQL cluster](https://safekit.evidian.com/wp-content/uploads/2023/02/safekit-prim-second-300.png) The replication is [synchronous](https://safekit.evidian.com/products/high-availability-software-for-application-clustering/synchronous-replication-vs-asynchronous-replication/) with no data loss on failure contrary to asynchronous replication. You just have to configure the names of directories to replicate in SafeKit. There are no pre-requisites on disk organization. Directories may be located in the system disk. ### Step 2. Automatic failover When Server 1 fails, Server 2 takes over. SafeKit switches the virtual IP address and restarts the Siemens Siveillance VMS and SQL application automatically on Server 2. The application finds the files replicated by SafeKit uptodate on Server 2. The application continues to run on Server 2 by locally modifying its files that are no longer replicated to Server 1. ![Failover of Siemens Siveillance VMS and SQL in a mirror cluster](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20300%20169'%3E%3C/svg%3E)![Failover of Siemens Siveillance VMS and SQL in a mirror cluster](https://safekit.evidian.com/wp-content/uploads/2023/02/safekit-stop-alone-300.png) The failover time is equal to the fault-detection time (30 seconds by default) plus the application start-up time. ### Step 3. Automatic failback Failback involves restarting Server 1 after fixing the problem that caused it to fail. SafeKit automatically resynchronizes the files, updating only the files modified on Server 2 while Server 1 was halted. ![Failback in a mirror Siemens Siveillance VMS and SQL cluster](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20300%20169'%3E%3C/svg%3E)![Failback in a mirror Siemens Siveillance VMS and SQL cluster](https://safekit.evidian.com/wp-content/uploads/2023/02/safekit-resynchro-alone-300.png) Failback takes place without disturbing the Siemens Siveillance VMS and SQL application, which can continue running on Server 2. ### Step 4. Back to normal After reintegration, the files are once again in mirror mode, as in step 1. The system is back in high-availability mode, with the Siemens Siveillance VMS and SQL application running on Server 2 and SafeKit replicating file updates to Server 1. ![Return to normal operation in a mirror Siemens Siveillance VMS and SQL cluster](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20300%20169'%3E%3C/svg%3E)![Return to normal operation in a mirror Siemens Siveillance VMS and SQL cluster](https://safekit.evidian.com/wp-content/uploads/2023/02/safekit-second-prim-300.png) If the administrator wishes the application to run on Server 1, this can be done manually through the web console at an appropriate time, or automatically through configuration. ### How to configure a SafeKit Mirror Cluster for Siemens Siveillance VMS and SQL? ![SafeKit Web Console: High Availability configuration dashboard for Siemens Siveillance VMS and SQL showing heartbeat networks, virtual IP setup, and real-time directory replication for a mirror cluster.](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20763%20497'%3E%3C/svg%3E)![SafeKit Web Console: High Availability configuration dashboard for Siemens Siveillance VMS and SQL showing heartbeat networks, virtual IP setup, and real-time directory replication for a mirror cluster.](https://safekit.evidian.com/wp-content/uploads/2026/01/safekit-mirror-cluster-config.png) The **SafeKit web console** provides an intuitive interface to orchestrate high availability for your critical applications. In just a few steps, you can configure a **SafeKit mirror cluster** to ensure business continuity: * **Application Failover (Macros Tab):** Define the specific application services to be automatically restarted in the event of a failure. * **Heartbeat network(s):** Dedicated communication path(s) used by cluster nodes to continuously monitor each other's health and availability and synchronize failover decisions. * **Virtual IP Management:** Set up the Virtual IP (VIP) for transparent client reconnection after a failover. * **Real-Time Replication:** Select the critical directories for host-based, synchronous byte-level replication. * **Checkers:** Monitor the application's health and trigger automatic recovery if a process failure is detected. The SafeKit cluster includes a dedicated split-brain checker to resolve network isolation issues without the need for a third witness machine or an additional heartbeat network.

It allows administrators to monitor the **operational state** of the cluster and track data synchronization in real-time. For a 2-node mirror cluster, the console clearly displays the roles of each server: * **PRIM (Primary):** The active node currently running the application and managing the Virtual IP. It performs writes to the local storage and real-time replication to the secondary node. * **SECOND (Secondary):** The standby node receiving synchronous byte-level updates. It is ready to take over instantly if the Primary fails. * **ALONE State:** Visually alerts you when the cluster is running on a single node (e.g., during maintenance or after a failure), indicating that redundancy is temporarily lost. * **Resynchronization Progress:** When a failed node recovers, its status turns orange during background data reintegration, ensuring no downtime during the "return to normal" phase. Beyond simple status icons, the interface provides **one-click failover orchestration**, allowing you to manually reassign the primary role for planned maintenance while ensuring continuous availability for user activity. ## SafeKit, a recognized solution on the security market ### Milestone has chosen SafeKit SafeKit is deployed in 30+ countries with the video management software of Milestone. [SafeKit is validated by Milestone](https://www.milestonesys.com/technology-partner-finder/evidian/milestone-redundancy-and-high-availability/) for redundancy and high availability of the management server.
