Data Management: Simplified.

Simplify your data management with powerful features including data protection, snapshots, replication, scrubbing, data reduction, and security. Integrated enclosure management capabilities save time and effort by making it easy to monitor the state of your drives from a single screen.

Proven Data Protection

Built on the self-healing OpenZFS file system, the TrueNAS R-Series features powerful data protection tools like copy-on-write and automatic bit-rot detection to prevent corruption. Built-in RAID protection, unlimited snapshots, and resilient replication protect your data and make it easy to restore data in the event of hardware failures or malware attacks.

Scale Up or “SCALE” Out

The TrueNAS R-Series appliance can be installed with any edition of TrueNAS. Choose TrueNAS CORE or Enterprise to use the R-Series for conventional, general-purpose storage or install SCALE to start laying the foundation for a scale-out storage cluster. Start with a single R-Series node and build out as your needs grow.

Flexible Integration

Integrating TrueNAS into your workload is easy with support for block, file, and object storage protocols as well as integrated support for all major virtualization hypervisors and cloud sync services. Additionally, all TrueNAS systems are fully compatible and allow secure data replication and migration between each other.
