Using Local Replication Setting Up a Simple Replication Task Overview Configuring a Local Replication Task Using Local Replication A local replication creates a zfs snapshot and saves it to another location on the same TrueNAS SCALE 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.
Snapshots Screen Show Extra Columns Snapshot Details Screen Dataset Rollback from Snapshot Window Clone Snapshot and Promote Dataset Delete Snapshot Batch Operations - Delete Add Snapshot Screen The Snapshots screen, accessed from the Datasets screen by clicking Manage Snapshots on the Data Protection widget, provides a list of existing snapshots filtered for the snapshot you selected, allows you to add new or manage existing snapshots.
The Snapshots screen also opens when you click Snapshots on the Periodic Snapshot Tasks widget found on the Data Protection screen.
Creating a Snapshot From the Data Protection Screen From the Datasets Screen Snapshots are one of the most powerful features of ZFS. A snapshot provides a read only point-in-time copy of a file system or volume. This copy does not consume extra space in the ZFS pool. The snapshot only records the differences between storage block references whenever the data is modified.
Why do I want to keep snapshots? expand Snapshots keep a history of files and provide a way to recover an older or even deleted files.
Viewing the List of Snapshots Deleting a Snapshot Deleting with Batch Operations Using Revert Browsing a Snapshot Collection Viewing the List of Snapshots 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.

New namespace and command documentation is continually added and maintained, so check back here often to see what is new! Snapshot Namespace The snapshot namespace has 10 commands, and is based on snapshot creation and management functions found in the SCALE API and web UI.
Creating a Periodic Snapshot Task Using the Advanced Scheduler Using Naming Schemas Setting Snapshot Lifetimes 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 SCALE storage snapshots from the Periodic Snapshot Tasks widget.
How should I use snapshots? expand Snapshots do not make not copies of the data so creating one is quick and if little data changed, they take very little space.

You must power on virtual machines for TrueNAS to copy snapshots to VMware. The temporary VMware snapshots deleted on the VMware side still exist in the ZFS snapshot and are available as stable restore points. These coordinated snapshots go in the VMware Snapshots list.
Use this procedure to create ZFS snapshots when using TrueNAS SCALE as a VMWare datastore. VMware Snapshots coordinate ZFS snapshots when using TrueNAS as a VMware datastore.
