Configuring Advanced Settings
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.
Advanced settings have reasonable defaults in place. A warning message displays for some settings advising of the dangers of making changes. Changing advanced settings can be dangerous when done incorrectly. Use caution before saving changes.
Setting Up a Local Replication Task
A local replication creates a ZFS snapshot and saves it to another location on the same TrueNAS system using different pools, datasets, or zvols. This allows users with only one system to take quick data backups or snapshots of their data when they have only one system.
If you have only one pool, create a dataset in that pool to store the replication snapshots. You can use a zvol for this purpose. If configuring local replication on a system with more than one pool, create a dataset for the replicated snapshots on one of those pools.
Setting Up an Encrypted Replication Task
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.
Adding Periodic Snapshot Tasks
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.
Setting Up a Remote Replication Task
Remote replication backs up data stored on an originating TrueNAS system to a second remote destination TrueNAS system. TrueNAS allows scheduling a one-time or regularly scheduled ZFS snapshot of data stored in pools, datasets, or zvols, and saves them in another system.
With the implementation of the administration user and role-based permissions, setting up replication tasks as an admin user has a few differences from those set up when logged in as the root user. Setting up remote replication when logged in as the admin user requires selecting Use Sudo For ZFS Commands.
Unlocking a Replication Encrypted Dataset or Zvol
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 Screens
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. The widget shows a description of periodic snapshot tasks when a task is not configured.
Replication Task Screens
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.
Advanced Replication Tasks
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.
Replication from one pool or dataset to another pool or dataset on the TrueNAS system is called local replication. Replication from the TrueNAS system to another TrueNAS or other backup server is called remote replication. Both local and remote replication can involve encrypted pools or datasets.
Advanced Settings Screen
Advanced settings have reasonable defaults in place. A warning message displays for some settings advising of the dangers of making changes. Changing advanced settings can be dangerous when done incorrectly. Use caution before saving changes.
Make sure you are comfortable with ZFS, Linux, and system configuration, backup, and restoration before making any changes.
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, NTP servers, allowed IP addresses, isolated GPU device(s), self-encrypting drives, and global two-factor authentication.
