Introduction to ZFS Replication

Storage replication

Replication is an OpenZFS feature that really ups the data management game, providing a mechanism for handling a hardware failure with minimal data loss and downtime. Fortunately, replication itself is easy to configure and understand. In this article we’ll keep things simple, and practice replicating small amounts of data to a virtual machine.

Basics of ZFS Snapshot Management

One of the many powerful features of OpenZFS are snapshots. OpenZFS stands out in its snapshot design, providing powerful and easy-to-use tools for managing snapshots. Snapshots complement a backup strategy, as they are instantaneous and don’t require a backup window. Since snapshots are atomic, they are not affected by other processes and you don’t have to stop any running applications before taking a snapshot.
In this article we’ll start with the basics: creating, using, and deleting file system snapshots.
