Enterprise NAS Storage
TrueNAS ZFS
Deploy enterprise NAS with TrueNAS — the most reliable ZFS file system on the market. Anti-ransomware immutable snapshots, encrypted off-site replication, native S3. No subscription, no vendor lock-in.

TrueNAS enterprise features
Immutable ZFS snapshots
Instant snapshots (0 seconds), unmodifiable even by share administrators. Ransomware encrypting your SMB files cannot reach the underlying ZFS snapshots.
Off-site replication
Encrypted incremental replication to a second site (DR office, datacenter, S3 cloud). Only modified blocks are transmitted. Configurable RPO to the minute.
Compression & deduplication
Transparent LZ4 compression (20–50% space savings depending on data type). Deduplication for VM environments: store 10 TB of VMs in 3 TB physical space.
Multi-protocol
SMB 3.1.1 (Windows), NFS 4.1 (Linux/VMware), iSCSI (databases), S3 (native MinIO), FTP/SFTP. A single NAS for all your network clients.
AES-256 encryption
Per-dataset encryption with master key. Encrypted volumes at rest (FIPS 140-2 compatible). Ideal for GDPR compliance and health/financial data.
Monitoring & alerts
Disk SMART dashboard, failure prediction, email/SNMP alerts, Grafana/Prometheus integration. Real-time data corruption detection (ZFS scrub).
TrueNAS vs Synology / QNAP — Why choose TrueNAS?
For businesses with critical data, TrueNAS ZFS provides data integrity guarantees that proprietary NAS cannot match.
Guaranteed integrity
TrueNAS checks every block on read. Synology/QNAP use EXT4 or Btrfs — susceptible to silent bit rot. ZFS automatically detects and corrects corruption.
Reduced total cost
TrueNAS runs on your own standard server hardware — no proprietary hardware at 3–8× the price. No cloud subscription. No per-bay licence. 100% free software.
Performance
On equivalent hardware, TrueNAS with SSD cache (L2ARC + SLOG) outperforms high-end proprietary NAS in iSCSI latency and SMB throughput.
Frequently Asked Questions
Is TrueNAS a serious alternative to Synology or QNAP?
Yes, for enterprises. TrueNAS SCALE is based on Debian + ZFS. It is used in production by Netflix, Dropbox and thousands of companies. The difference: TrueNAS runs on your own hardware, without subscription, without vendor lock-in. Synology/QNAP offer a better user experience for small volumes (home NAS/light SME), TrueNAS is superior for critical enterprise data.
Does ZFS really protect against ransomware?
ZFS snapshots are immutable at the OS layer. Even ransomware with admin rights on SMB shares cannot encrypt or delete them. Replication to a second site adds geographic protection. This is the most effective ransomware defence after EDR.
What hardware configuration do you recommend?
For a 20–100 user SME: x86-64 server with ECC RAM (minimum 32 GB — ZFS requires it), 6–12 SATA/SAS HDD disks + 2 SSDs for cache (L2ARC) and log (SLOG). 10 GbE network connection recommended. Convergent sizes and integrates the full setup.
Does TrueNAS integrate with Proxmox VE?
Perfectly. TrueNAS exposes an iSCSI or NFS datastore that Proxmox VE uses natively as shared VM storage — equivalent to a 30,000 TND SAN at a fraction of the cost. Proxmox Backup Server (PBS) then uses TrueNAS ZFS as a backup target with native deduplication.
