TrueNAS Server

ZFS Filesystem Foundation

TrueNAS Server uses OpenZFS as its core storage engine, which automatically detects and repairs data corruption through checksums, self-healing, and copy-on-write architecture.

Storage Pool Creation

Users configure virtual storage pools (vdevs) by combining disks into RAID-Z, mirrors, or stripes, providing redundancy and performance optimization without traditional hardware RAID controllers.

Network Sharing Protocols

Supports SMB/CIFS for Windows, NFS for Linux/Unix, AFP for macOS, iSCSI for block storage, and S3-compatible object storage for seamless multi-platform access.

Snapshot and Replication

Creates unlimited, space-efficient snapshots for point-in-time recovery and enables scheduled replication to remote systems for backup and disaster recovery.

Web-Based Management

Features an intuitive web UI for pool management, user permissions, sharing configuration, monitoring, and plugin or VM deployment with REST API support for automation.

Data Protection Layers

Implements inline compression, deduplication, encryption, and scrubbing to maximize storage efficiency and security while preventing bit rot and ransomware threats.

Plugin and Virtualization

Runs FreeBSD jails for lightweight apps like Plex and supports the bhyve hypervisor for virtual machines, expanding TrueNAS into a full-featured storage platform.

High Availability Setup

Supports clustering and failover configurations for mission-critical environments, ensuring continuous data access during hardware or node failures.
