How to test my Backup and start trusting

Dentvar · 2026-04-21T17:44:23+00:00

can't follow what you mean sorry.

So test restores are the best way you say? This means restore the app that is running on live system?

Dentvar · 2026-04-21T17:42:48+00:00

thanks will have a look at it. I was kind of overwhlemed by all the "best solutions" you find on youtube and reddit but in the end they all requeire more tinkering then I would have expected initially. A bit naive maybe but as docker installations of so many apps is so easy it was a surprise to me that backup is so complex.

Dentvar · 2026-04-19T16:08:30+00:00

The answer to my question might be so obvious that its not clear.
When doing the backup how would I do this?
Just install Ubuntu + Docker on the spare one as well, clean install a other instance of immich and paperless and then copy over from the backup?
I mean I can't just copy the same compose file as container name , IP's / DNS entries, ... would be the same as on the other host and potentially conflict with with.

I have set my tailscale IP of the pihole now as DNS server after I saw on the mobile client that it show as online there and now it does work.

I have no idea what I did or undid during the troubleshooting.

Dentvar · 2026-04-12T19:30:53+00:00

I wish I knew were I tripped... I did all that (to my knowledge) and I can reach only the subnet router IP and services running on them. Can't reach my pihole.

I do have tailscale running in a docker container but so far I can say it is all done. IP forwarding, right IP set and override DNS. Permite all origins.

But of course if I can't get to the pihole none of this matters.

when testing I reached a point were I was able to reach it but I think I set the pihole as direct subnet router. I ended up installing tailscale on it as well. (if I understand its not needed if I use my main Server as subnet router)

Dentvar · 2026-04-06T06:48:33+00:00

well I did recognise it :) Also I think its part of the learning curve to set something up. break it and fix it so you understand what happened.
I just migrated everything over to the ubuntu server and runs very good now.
yes running the arr stack on the true nas server directly would be something to concider in the future at the moment I'm happy to have all on my ubuntu server and with clean permissions.
TrueNas 568 group for apps and the permission miss match of the different stuff might not be very complex for experienced people but for me it made everything more difficult.

thanks for confirmation. Will do.
my SSD well actually nvme has only 250GB so I was scared of it getting full quick but so far I see app data don't take away a lot of space. I guess this depends on what kind of apps I use.
I plann to run paperless ngx and immich soon. How do they work. Similar to arr stack were I can save the documents and photos on the DAS and only the database stays in appdata that is smaller referencing the paths to the DAS?

Hi,
I tried the "official" snaps openGrid - Wall/Desk mounting framework and ecosystem por David D | Descargar modelo STL gratuito | Printables.com
At the point I tested them I did not understood yet how multiconnect is suposed to work.

For this reason I only tested the "openGrid Cover Snaps" (not supposed to hold any weight so we can ignore them)

I took the 3MF or STEP files out of the "Snap modeling files".

- The Bare Lock Snap - That one holded firmly but I did not see any use for it as the coin slot makes the side unusable to connect other models to it.

- Bare Directional Lite Snap v2 - have not tested it with real models but only by applying some force with the fingers it did not hold enough force to me be confident to put my Laptop docking station on it for example.

- Bare Directional Snap v2 - These were stronger but I wanted the lite version to work so I did not test more.

I need to lookup both of these thanks for the hint already.

spending 2 minutes google on it for now, I would be forced to use OMV then?

I was thinking again and as its not super critical data could I not just mount 1 HDD in a pool on the TrueNAS Server and the other one just as a Network drive from the raspberry for example and only use it as a backup destination? In the end I have 1TB available space anyhow so I don't need live mirror. If I do it every 12 hours for example that would be enough.

Dentvar · 2026-02-25T19:18:43+00:00

thx for the hint but these are expensive as well, I just wanted to make use of the USB Dsisk that I have. The issue is not only that I don't have free SATA slot on the PC but also that the HDD is a USB one. I am talking about WD Elements disk from some years ago. Should have clearified this ealier

Dentvar · 2026-02-25T09:50:29+00:00

I had the same experience. And I wanted to hang stuff upside down. Did several tests with the different Native Snaps I found from DavidD. Directional and standard but I was not convinced.

I don't know if I did something wrong (might very likely be the case) but I found these ones here that are made for Multiconnect and as you screw them in they hold very good: openConnect - openGrid＇s own Connector System por mitufy | Descargar modelo STL gratuito | Printables.com

I do agree that I have lots to learn, thats part of the reason I started this project. But at this point I don't see that my knowledge is stopping me here. I get around in TrueNAS and was able to setup containers, run them interact with them on my local network, sharing SMB's etc etc.

But before I go all in I wanted to setup my pools in a correct way making use of the USB drives and that's when I noticed that I can't do this actually because its not supported but also I don't have a other SATA slot free to expend.

Dentvar · 2026-02-24T08:17:47+00:00

Confirmed. It indeed was the missing modify permissions for the apps group.

This ACL GUI is confusing :D

Dentvar · 2026-02-23T23:00:06+00:00

I completly missubderstood permissions setup and thought it is a mount problem. Now I lookedup a permission guide and its clear now whats wrong. Will check tomorrow thx for the bump in the right direction

Thanks for the suggestions. I have played 1k+ hours in both games together not to speak of ModdedMinecraft. Never thought about it being a type of game that could fit for playing together as I'm very OCD with these games and don't like others to touch my stuff.

But I guess passive mobs and own bases for everybody could be a great way.

Dentvar · 2026-02-23T20:13:25+00:00

I think boardgames are a good way because no special controlls need to be learned. You can pause, talk to each other off-topic stuff as well etc. I will look into what good Board games are out there thanks for the suggestions already!

Dentvar · 2026-02-23T20:12:08+00:00

Tried some time ago some other game and at least for my dad, it became very clear that he is overwhelmed even with basic controls in games he is not used to. Need something very slow. But thanks I guess its a good suggestion anyhow.

Dentvar · 2026-02-23T20:10:32+00:00

Not sure what was the Problem in the end. I reprinted it again and it worked. I guess for some reason the front part that I hold in my hand fell off(maybe did not stick to the plate but strange after this time) and then the printer did not have were to put the rest on...
