Ubuntu 19.10 Install with ZFS some Tweaking and Snapshots

In this video I will be installing Ubuntu 19.10 Code Named Eoan Ermine, I will be installing with the new experimental file system ZFS, be cautious if trying it, it's best to have one whole disk alone to install to, installing with ZFS will take up the whole disk and delete everything on it. The original install will be completed within a Virtualbox setup as I had some trouble getting my simplescreenrecorder working on real hardware. Post install regarding theming and tweaking is performed on my Desktop PC. After initial setup I take a look at ZFS Snapshots and the process involved, this was performed once again in a Virtualbox setup as I found out the hard way that recording while rolling back Snapshots is a very bad idea Lol!!! Hope you enjoy the video.

Start of install - 03:45
Setup on Real Hardware - 07:56
Snapshots - 28:26

Nice one Colin. Made me realise I'm still such a noob with certain things! :)

Yesterday I installed new 20.04 on ZFS, and watching your video to get to know a little bit about snapshots.
You just made my life easier and safer I guess, because I manage to do snapshot of freshly clean ubuntu.
Thanx.

your plan (0:45) paid off—this was just what i wanted!

Yes, ZFS can have 64k snapshots. Normally you take a snapshot each hour or day or week and if you need the space again, you destroy e.g. the oldest snapshots or you delete 3 of the 4 weekly snapshots in a month. Currently I have 8 snapshots with the oldest from 14th of July. I kept one snapshot from July, August and September and for October and November I have weekly snapshots. Saturday on my snapshot/backup day I will delete 3 snapshots of October except the one in the middle of the month.

You should also snapshot the OS itself and you can produce nice scripts for snapshotting all those datasets. Three scripts one for snapshot, destroy and rollback, with the snapshot name as $1 parameter. I boot from ZFS since January and on two occasions it saved me from doing a reinstall or a complex recovery. Once when I detected that Virtualbox did not work with Linux 5.3, I even rolled back the upgrade to "Ubuntu 19.10 Beta" and rebooted again in Ubuntu 19.04 :) :)

Normally I use e.g 191116 as snapshot names, it nicely sorts your snapshot listings on date. But Saturday for the OS snapshot I will use 191116R23, to indicate that it is the first snapshot with Linux 5.3.0-23. In general I snapshot the OS once per month, since you can always rollback and rerun the updates, but you could insert an additional snapshot before you upgrade in future to 20.04 :).
