A local replication creates a zfs snapshot and saves it to another location on the same TrueNAS system either using a different pool, or dataset or zvol. This allows users with only one system to take quick data backups or snapshots of their data when they have only one system. In this scenario, create a dataset on the same pool to store the replication snapshots. You can create and use a zvol for this purpose. If configuring local replication on a system with more than one pool, create a dataset to use for the replicated snapshots on one of those pools.

TrueNAS replication allows users to create replicated snapshots of data stored in encrypted pools, datasets or zvols as a way to back up stored data to a remote system. You can use encrypted datasets in a local replication.

Advanced Settings provides configuration options for the console, syslog, kernel, sysctl, replication, cron jobs, init/shutdown scripts, system dataset pool, isolated GPU device(s), self-encrypting drives, system access sessions, allowed IP addresses, audit logging, and global two-factor authentication.

TrueNAS Enterprise

Enterprise-licensed system administrators have additional options to configure security-related settings, such as FIPS and STIG compatibility and Self-Encrypting Drive (SED) configuration.

The Advanced Settings screen provides configuration options for the console, syslog, audit, kernel, sysctl, storage (system dataset pool), replication, WebSocket sessions, cron jobs, init/shutdown scripts, allowed IP addresses, isolated GPU device(s), self-encrypting drives, and global two-factor authentication.

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

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.

Periodic snapshot tasks allow you to schedule creating read-only versions of pools and datasets at a given point in time. You can also access VMWare snapshot integration and TrueNAS storage snapshots from the Periodic Snapshot Tasks widget.

The Data Protection screen Periodic Snapshot Task widget displays periodic snapshot tasks created on the system. A periodic snapshot task allows scheduling the creation of read only versions of pools and datasets at a given point in time.

Periodic snapshot tasks display the machine time, browser time, or both depending on individual user timezone settings. Users can update timezone settings by utilizing the General Settings screen.

The Periodic Snapshot Task widget displays a list of tasks configured on the system.

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. 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.

The Replication Tasks widget displays No Replication Tasks configured before you add a task.
