TrueNAS users should either replicate the dataset/Zvol without properties to disable encryption at the remote end or construct a special JSON manifest to unlock each child dataset/zvol with a unique key.

On March 31, 2025, Google changed the Google Photos API to allow external applications to access and manage only the media and albums they create. Cloud sync tasks continue to upload photos to albums created by the TrueNAS sync client, but reading from your full photo library or from shared albums does not work as expected. Some operations return permission errors.

TrueNAS stores cloud backup services credentials, SSH connections, and SSH key pairs configured using the widgets on the Backup Credentials screen. Users can set up backup credentials with cloud and SSH clients to back up data in case of drive failure.

The Backup Credentials screen displays the Cloud Credentials, SSH Connections, and SSH Keypairs widgets.

Click Add on the widget for the type of credential to add to open that configuration screen.

Taking snapshots requires the system have all pools, datasets, and zvols already configured.

File Explorer limits the number of snapshots Windows presents to users. If TrueNAS responds with more than the File Explorer limit, File Explorer shows no available snapshots. TrueNAS displays a dialog stating the dataset snapshot count has more snapshots than recommended and states performance or functionality might degrade.

There are two ways to view the list of snapshots:

After configuring your TrueNAS storage and data sharing or any other function, service, or application, it is time to ensure an effective data backup.

You should also:

• Download and save your system configuration file to protect your system configuration information.
• Download a debug file.
• Create a boot environment to use as a restore point.
• Backup Stored Data

TrueNAS provides several options to set up a data storage backup method, including using a cloud sync provider and a scheduled task or configuring a replication task.

The SSH service lets users connect to TrueNAS with the Secure SHell Transport Layer Protocol. When using TrueNAS as an SSH server, the users in the network must use SSH client software to transfer files with SSH.

Allowing external connections to TrueNAS is a security vulnerability! Do not enable SSH unless you require external connections. See Security Recommendations for more security considerations when using SSH.

To configure SSH go to System > Services, find SSH, and click edit to open the basic settings General Options configuration screen.

The System > Services > SSH screen allows you to set up SSH service on TrueNAS.

Click edit to open the Services > SSH configuration screen.

You must also configure SSH backup credentials to allow SSH access. See SSH Screens for more information.

TrueNAS advanced replication allows users to create one-time or regularly scheduled snapshots of data stored in pools, datasets, or zvols on their TrueNAS system as a way to back up stored data. When properly configured and scheduled, local or remote replication using the Advanced Replication Creation option takes regular snapshots of storage pools or datasets and saves them in the destination location on the same or another system.

The Replication Task widget on the Data Protection screen lists replication tasks configured on the TrueNAS system. The widget shows a definition of replication tasks before adding a task when none exist on the system.

Replication tasks work with periodic snapshot tasks to complete the replication. After scheduling a replication task, the Periodic Snapshot Task widget shows a new task for the newly added replication task.
