1. Setting Up Storage

TrueNAS Scale offers many advanced storage options that allow you to configure the underlying storage as the base for your home server.

Disk Image, Zvols, and Storage System

TrueNAS Scale is built around the ZFS file system and ZVOLs. ZVOLs provide a block device storage solution that is scalable, performant, and resilient.

Once you have installed TrueNAS Scale, you will navigate to the Storage dashboard and Create a new Pool.

You can setup:

  • Windows SMB Shares

  • UNIX NFS Shares

  • Block (iSCSI) targets

  • WebDAV

3. Configure data backups or replication

One of the things I like about TrueNAS is that it has a wide range of ways to back up your data. These include the following:

  • Cloud sync – TrueNAS can send, receive, and perform data syncs with a cloud storage provider. It supports all the major providers, including: Amazon S3, Backblaze B2, Box, Dropbox, FTP, Google Cloud Storage, Google Drive, Microsoft Azure Blob, OpenStack Swift, etc

  • Periodic Snapshots – With periodic snapshots, you can create read-only versions of pools and dataset. You can also access VMware snapshot integration and storage snapshots from the snapshots task widget in TrueNAS Scale.

  • Rsync – Rsync allows you to copy data to another system for backup or you can also use it when migrating to a new system. You can either push or pull data .

  • Replication – Replication allows you to setup one-time or regular scheduled snapshots of your pool data, datasets, or ZVOLS. It takes regular snapshots of storage pools or datasets and saves them to the destination location which can be a different TrueNAS Scale solution.


Be sure to setup some type of data protection sooner than later. While TrueNAS and ZFS are highly resilient, mistakes happen and other data loss events happen. Backups are often forgotten after you are up and running and can lead to disaster if you don’t configure something to protect your data and have multiple copies stored outside of your NAS.

Scheduled Backups and High Availability

You can help avoid data loss by scheduling daily, weekly, or monthly backups. Enhancing this with the high availability feature of TrueNAS Scale can significantly reduce downtime.

4. Configure virtual machines, containers, and apps

TrueNAS Scale provides virtual machine software capabilities, allowing you to run virtual machines directly on your TrueNAS instance without a separate physical computer. You can run Windows VMs, Linux, and others with the operating systems running inside the TrueNAS Scale host computer.

Understanding Virtual Machines and Operating Systems

TrueNAS Scale allows you to run virtual machines with multiple operating systems. Running a virtual machine VM on the TrueNAS host system makes spinning up a Windows VM or Linux machine straightforward. TrueNAS Scale allows for virtual machines to perform with emulated virtual hardware, bridging the gap between virtual and actual hardware. So, in other words, you don’t need to have an extra virtualization host. You can do this natively with TrueNAS Scale.

Like VMware, Proxmox, XCP-ng, and others, the guest operating system runs inside the boundaries of the configured VMs inside TrueNAS. You are only limited in the number of VMs by the amount of system resources the host system supports.

Add your image file, use an existing disk image with your TrueNAS Scale instance, and load your virtual machine from the disk image.

Containerization: Docker and Linux Containers

In addition to using virtual machines, TrueNAS Scale allows you to embrace Docker containers and Linux containers fully, offering modern virtualization technologies to spin up services in your home lab environment more efficiently. Note the apps you can easily install in the applications section of TrueNAS Scale.

VM Settings for Storage

Remember that fine-tuning VM settings can drastically impact the performance of virtual machines in your TrueNAS Scale. Setting the correct memory size, allocating appropriate system RAM, and ensuring a balanced allocation between virtual CPUs can make a significant difference.

It is always a best practice to only allocate the resources needed for the workload. Overprovisioning can negatively impact the performance. You want it to be as lean as possible while having the needed resources.

5. Secure your TrueNAS Scale installation

Like any technology system, securing TrueNAS is extremely important. Note the following technologies built into TrueNAS Scale for security:

  • Data encryption – TrueNAS offers the ability to encrypt your TrueNAS storage pool. You can encrypt the root dataset of a new storage pool and all datasets added to a pool will inherit encryption.

  • Two-factor authentication – 2FA authentication has become the standard of securing authentication. It is great to see that TrueNAS Scale has this built-in. Be sure to get 2FA setup and configured before you go into production in the enterprise or home lab.

  • Use of cloud credentials and SSH keys – It also provides additional credential mechanisms, such as cloud credentials and SSH keys for more secure auth methods.

  • Syslog capabilities – For auditing purposes, be sure to enable the Syslog features built into TrueNAS. You can send Syslogs to your Syslog server you use for detailed log searching, etc.


Be sure to configure Two-factor auth as one of the first setup steps in your TrueNAS Scale installation.
