Expected Outcome

A working TrueNAS replication environment with automated snapshot schedules and a validated rollback procedure for data recovery.

Assumptions

Basic understanding of network configuration
Familiarity with TrueNAS interface
Two or more systems capable of running TrueNAS (physical or virtual)

Bill of Materials

TrueNAS installation media (USB or ISO)
Two or more servers or virtual machines
Network switch or router
Cables for network connectivity
Sufficient storage for data replication

Build Steps

Install TrueNAS on both servers
Download the TrueNAS installation media and install it on both servers.
Example pattern only. Adjust for your environment before running.
```
Download TrueNAS from the official website.
Create a bootable USB drive with the TrueNAS ISO.
Boot each server from the USB drive and follow the installation prompts.
```
Configure network settings
Set up the network settings for both TrueNAS servers to ensure they can communicate with each other. Manual action: Navigate to Network > Interfaces and configure the IP addresses.
Example pattern only. Adjust for your environment before running.
```
Access the TrueNAS web interface via the IP address.
Ensure both servers are on the same subnet.
```
Create datasets for replication
On the primary TrueNAS server, create datasets that will be used for replication. Manual action: Go to Storage > Pools > Add Dataset.
Example pattern only. Adjust for your environment before running.
```
Name the dataset (e.g., 'ReplicationDataset').
Set permissions as needed.
```
Set up snapshot schedules
Configure automated snapshot schedules on the primary TrueNAS server to take regular snapshots of the dataset. Manual action: Navigate to Tasks > Snapshots; Click on 'Add' to create a new snapshot task; Select the dataset and set the schedule (e.g., every hour).
Configure replication task
Set up a replication task on the primary TrueNAS server to replicate the dataset to the secondary TrueNAS server. Manual action: Go to Tasks > Replication Tasks; Click 'Add' to create a new replication task; Select the dataset and the target server's IP address.
Validate snapshot rollback
Test the rollback feature to ensure that snapshots can be restored correctly. Manual action: Navigate to Storage > Snapshots on the primary server; Select a recent snapshot and click 'Rollback'.
Example pattern only. Adjust for your environment before running.
```
Verify that the dataset is restored to the state of the selected snapshot.
```
Monitor replication and snapshots
Regularly check the status of replication tasks and snapshot schedules to ensure they are functioning as expected. Manual action: Go to Tasks > Replication Tasks to view the status.
Example pattern only. Adjust for your environment before running.
```
Check Storage > Snapshots for the list of snapshots.
```

Validation

Verify that snapshots are being created as per the schedule.
Ensure that replication tasks complete successfully without errors.
Test the rollback process to confirm data integrity.

Troubleshooting

Check service logs before changing the design.
Confirm ports, paths, credentials, DNS names, and container names match the guide assumptions.

Cleanup or Rollback

Stop test services you no longer need and keep a copy of working configuration before deleting volumes or data directories.

Next Improvements

Explore additional TrueNAS features such as cloud sync and user permissions.
Consider implementing alerts for snapshot and replication failures.
Expand the lab by adding more datasets and replication targets.
