OpenZFS – OpenZFS, Your Data and the Challenge of Ransomware
As commercial storage becomes increasingly expensive, more and more of the Education vertical is looking at Open Source solutions for storage. In this article, we discuss the value of OpenZFS for Universities and how system administrators can best leverage it to their benefit.
FreeBSD vs. Linux – Which Operating System to use for OpenZFS
Age-old discussion: ZFS running on Linux or FreeBSD? We’re not going to set out to tell you which operating system you should use. Both choices are excellent — but we’ll lay out how different (or alike) it is to run OpenZFS on either to help anyone on the fence decide which OS to use beneath our favorite filesystem.
httm – The Hot Tub Time Machine is Your ZFS Turn-Back-Time Method
You may already know how powerful ZFS snapshots are at enabling simple recovery from accidentally or maliciously deletion or corruption of files, but with a tool like Hot Tub Time Machine (HTTM) you can manage this on a per file basis even more easily. Enabling self-service restoration can reduce the load on your IT team, and HTTM even works on machines that do not use ZFS, as long as they are backed up to ZFS.
Tuning recordsize in OpenZFS
For many people, tuning OpenZFS isn’t really necessary—performance on the conservative default settings is more than ample to get what they need done.
However, To get the best performance, matching the recordsize to your application provides a large performance boost. Learn how to match your dataset to your workload.
Should I Upgrade to OpenZFS 2.1?
Beginning with version 13.0, FreeBSD supports the long-anticipated OpenZFS native encryption. If you’ve used FreeBSD’s GELI encryption in the past, you may wonder if switching to OpenZFS native encryption makes sense.
Check out the differences between GELI encryption and OpenZFS native encryption, and the main benefits of native encryption, let’s take a look at how to create an encrypted database and reroot to an encrypted database.
NFS Shares with ZFS
Why would you use the sharenfs property for NFS configuration and how to do so? FreeBSD’s built-in integration of OpenZFS and NFS makes it easy for any administrator to configure and manage NFS shares. By using OpenZFS’ sharenfs property, managing NFS shares can be added to your arsenal of scripts and procedures for monitoring and maintaining the data stored on OpenZFS filesystems.

Demystifying OpenZFS 2.0
OpenZFS 2.0 has been released for a while now and, needless to say, FreeBSD 13 was shipped with OpenZFS 2.0. However, there are still questions about how the change from feature flags happened and why version 2.0 of OpenZFS was decided.
With this article, we’re hoping to clear the air around the release of OpenZFS 2.0.
Advanced ZFS Snapshots
In our previous articles, we introduced you to the basics of ZFS snapshot management, and explained concepts such as creating OpenZFS snapshots, restoring files from a snapshot, and deleting snapshots.
With this article, we dive a bit deeper into OpenZFS snapshot management with snapshot holds, clone creation and promotion, and assigning permissions to snapshot-related operations.
Manipulating a Pool from the Rescue System
We’ve all been there: that moment of panic when a system fails to boot back up. Perhaps there was a glitch with an upgrade. Maybe you’re wondering if you fumble-fingered a typo when you made that last change to loader.conf.
Fortunately, with FreeBSD and its built-in rescue mechanisms it is possible to quickly recover from most scenarios that prevent a system from booting into normal operation. And if you’re using OpenZFS, you can rest assured that your data is intact.
With this article, let’s take a look at some common recovery scenarios.
