How to Set Up TrueNAS Cloud Sync Tasks for Off-Site Backup
The earlier replication guide covered sending ZFS snapshots to a second TrueNAS system, but not everyone has access to a second physical NAS for genuine off-site placement. TrueNAS Cloud Sync Tasks offers a built-in alternative, syncing data directly from your pools to cloud storage providers like Backblaze B2 or AWS S3 (covered in the earlier…

Understanding and Tuning ZFS ARC Cache in TrueNAS
If your TrueNAS system seems to be using far more RAM than any running service would explain, ZFS’s ARC is almost certainly why — and understanding ZFS ARC cache behavior prevents the common mistake of treating this as a problem needing to be “fixed” rather than the system working exactly as intended. What Is ARC?…

How to Set Up iSCSI in TrueNAS Scale for Proxmox Storage
The earlier SMB/NFS shares guide covered file-level sharing, but for VM storage specifically, block-level access via iSCSI offers a genuinely different performance profile — presenting TrueNAS storage to Proxmox as if it were a raw, locally-attached disk rather than a network file share, often with meaningful performance advantages for VM workloads. File-Level vs Block-Level Storage…

Choosing a ZFS Pool Layout: Mirror vs RAID-Z1 vs RAID-Z2
Creating a storage pool (referenced briefly in the earlier TrueNAS Scale introduction) asks you to choose a redundancy layout upfront — a decision that’s genuinely difficult to change later without rebuilding the pool from scratch. Understanding ZFS pool layout options properly before creating your pool saves you from discovering the wrong tradeoff months into using…

How to Set Up SMB and NFS Shares in TrueNAS Scale
Building storage pools is only half the picture — that storage needs to actually be reachable from your other devices and servers.

How to Set Up ZFS Replication in TrueNAS Scale for Off-Site Backup
Snapshots protect against accidental deletion and corruption on the same pool, but they don’t protect against losing the entire NAS itself — a drive…

Running Apps Directly on TrueNAS Scale: A Practical Guide
TrueNAS Scale Apps lets you deploy Docker-based services straight from the same web interface managing your storage pools, without needing a separate Pr…
