Réduction de la perte de données
Interruptions évitées
Organizations face constant threats to data availability: hardware failures, system outages, cyberattacks, human error, and unexpected environmental events. Any disruption can lead to downtime, data loss, and operational impact if data is not continuously accessible and recoverable.
To maintain business operations without interruption, you need a resilient business continuity and disaster recovery (BC/DR) strategy that works reliably across diverse infrastructure. DataCore enables you to strengthen availability, minimize data loss, and recover rapidly by applying proven BC/DR principles consistently across your storage environment.
- How do you keep data accessible when components fail?
- How do you prevent outages from disrupting operations?
- How do you protect against data loss or corruption?
- How do you recover if your primary systems go down?
- How do you restore data to a known good state?
- How do you refresh storage hardware without downtime?
Three Lines of Defense to Avoid Downtime and Data Loss
DataCore applies three proven principles to help organizations prevent downtime and maintain continuous access to critical data. These lines of defense work together to address a wide range of disruption scenarios from minor component failures to full-scale outages and unwanted data changes. By combining local redundancy and failover, remote recovery, and point-in-time restore, you can strengthen resiliency across your storage environment without redesigning existing infrastructure.
This layered model forms a flexible BC/DR framework that adapts to different operational requirements. You can implement any one of the lines of defense individually, expand to additional layers as needs evolve, or leverage all three together for maximum protection and continuity. The result is simplified planning, streamlined recovery processes, and the right level of resilience without unnecessary complexity.
Contournement des défaillances (HA)
Résout de petits problèmes, par exemple lorsqu'un système ou certains de ses composants tombent en panne. La réplication des données en temps réel au sein d'un site ou d'un cluster urbain, ainsi que le basculement automatique vers la deuxième copie garantissent un accès continu aux données, sans aucune perte.
Récupération à distance (DR)
Traite des pannes plus importantes (par exemple, inondations, incendies ou pannes de courant) qui ont un impact sur une région entière. La création de répliques dans un site distant/DR permet de restaurer l'accès rapidement et de réduire au minimum la perte des données en transit à partir de ce site distant.
Retour au dernier état sain connu
Permet de revenir à un état antérieur aux modifications indésirables telles que la suppression accidentelle de données, une erreur logique (bogue) ou une attaque externe. Les sauvegardes ponctuelles et les snapshots permettent de restaurer les données à partir d'une copie fiable lorsque de tels événements imprévus surviennent.

Two DataCore Platforms for Comprehensive BC/DR Coverage
SANsymphony for Data Center Business Continuity & Disaster Recovery
SANsymphony is a software-defined storage platform that provides the resilience foundation for data center environments. It virtualizes and centralizes storage resources across diverse systems so that protection, availability, and recovery can be managed consistently, regardless of underlying block storage hardware (SAN, HCI, DAS, JBOD, etc.).
By orchestrating how data is mirrored, replicated, and preserved across fault domains and sites, SANsymphony shields applications from the effects of hardware failures, outages, and unwanted data changes. It gives organizations a unified way to enforce BC/DR policies, maintain dependable access to critical information, and streamline the operational effort required to keep storage continuously protected as infrastructure evolves.
