Just wrote a blogpost about my adventures with #OmniOS #Illumos #ZFS replication using #ZRepl : https://extrowerk.com/2026-03-03/ZFS-replacation-with-zrepl.html

#zrepl works well on my new #OmniOS #VM

So, I did something silly. I started backing up my primary #FreeBSD desktop after .. omg nearly 30 years. It was first installed in ~1996 and has been continuously, incrementally upgraded since then. Hardware, OS upgrades, CPU, etc.

Anyway, I was going to try and convert it to use #zfs boot environments. That's something that can't be done in-place on a legacy installation from ~1996. It's using ZFS for years but the FS layout doesn't allow a trivial rename etc in single user mode.

Then I realized.. wait, I've got important stuff on there. It's not being backed up regularly. This might not be a great idea.

So, #zrepl to the rescue! So now there is a second copy. No, a restore has not been attempted but I am reusing a process that I have tested before. Close Enough(tm), right? Nothing Could Go Wrong With This Plan(tm), right?

(Why zfs boot environments? I'm working on fixing some really annoying FreeBSD pkgbase, pkg etc limitations/problems and boot envs would be damn convenient! And of course, backups.)
