Docker, Truenas, and self-hosting... (shredderfood.net)

So I've been self-hosting for a few years now...got a decent setup...

But I only really got into docker-compose in the last few months... I mean, I've used it through the "Apps" in TureNAS, but never directly....

I ran a mastodon host on a VM (giant pain in the ass) and a few other things that weren't available as apps, but never mainstream...

Once I got into it, I managed to get everything moved over to truenas as docker containers..

Last week it saved my ass...the AC in the house failed..and I was able to shut down everything save the Truenas (with a fan pointed at the front of the server) and keep everything up and running throughout..

So it's been helpful to know, and an awesome learning experience. (I'm happiest when I'm learning new things)

My question is this...

How do you back them up? I mean, I have snapshot backups of my docker-volume ZFS dataset, and replicate that to a remote host...but I'm not even sure I'd know how to recover it if I had to...is it just a file copy and restart?

Truenas is hardened enough that it's pretty hard to screw it up... you can't install packages or anything like that.. My goal was to have one server that's "Production" so that I can nuke the lab from time to time as needed. (I have a proxmox server, a VMWare server, and one that bounces back and forth between nutanix and whatever else I want to play with at the time...

Also have another R730XD that I use for proxmox backup server, 6x 12TB drives (that were my nas drives before I got the 22TB upgrades) PBS is an amazing application, even when I'm not using the proxmox VM's, the filesystem backups work like a champ, and it replicates backups to an NFS datastore in my other house (running on Truenas on a T630 under my desk)

Yeah I am pretty comfortable with CLI on linux, but I just never bothered with TrueNas. Also I am lazy and once something works I just leave it there even when I could improve it lol.

I have been meaning to venture into Proxmox as well but I don’t have the time or spare parts to get a new machine running atm. Maybe someday I’ll get around to it though as it seems like a nice playground without breaking things.

It's just Debian, no surprises.
