Today I was honored to give ZFS Boot Environments Reloaded talk at the NLUUG Najaarsconferentie 2018 (the NLUUG Autumn Conference 2018).

Dunno for how long the conference page will be available so below you will find both conference page and its program.

… and the program.

There were lots of interesting talks, I really liked the Salt workshop at the end of the day. I wanted to also attend Ansible presentation in the morning but having spend almost 17 hours in the car driving from central Poland to Netherlands I really needed some sleep 🙂

You are invited to download the PDF Slides – https://is.gd/BECTL – available here.

As I just finished the talk the video from the talk is not yet available, but I will update the post when it will be.

Besides obvious things that ZFS Boot Environments can do I also talked about upcoming FreeBSD 12.0-RELEASE improvements in this area. Currently FreeBSD 12.0-RELEASE is planned to be released around Christmas later this year and is at the BETA4 stage currently.

Also here is the abstract that I added at the conference page about the presentation.

Abstract As long as sysadmins need to maintain, change and update operating systems there is always need to protect against problems that may occur during these operations. Various solutions were used starting from simple backup/restore procedures or copying the contents of system filesystems into spare disks to snapshots and clones recently. None of these solutions were transparent enough or bulletproof enough to provide complete and consistent protection again failures in the change or update process. One of such holy grails is ZFS Boot Environments solution. It protects entire system (and even additional data when needed) against almost any change or update process. As ZFS Boot Environments matured in Solaris/Illumos systems and then on FreeBSD UNIX other systems started to copy its principles to provide similar solutions such as snapper with BTRFS in SUSE or Boot Environment Manager for DragonFly BSD with their HAMMER filesystem. The presentation aims to walk through the history of these solutions with the focus on practical ZFS Boot Environments solutions and examples.



Hope you will enjoy it.
