Sure thing—autofs is a pretty cool utility and it works with SMB as well.

If the storage isn’t present for PBS, the backup would fail. There are files inside the directory that PBS will notice are missing.

Mounting the NFS export in the PVE host is the simplest way to get shared storage into an LXC container. You have to fight apparmor to mount NFS or SMB inside the container directly.

No, I used an unprivileged container and I set the permissions on the NFS server to accommodate that.

I use it like I might use unbound or dnsmasq, but I’d think of it more like bind. It’s can be used as a recursive or authoritative resolver. It supports all kinds of protocols (DOT, DOH, DNSSEC, etc). Handles zone transfers easily. It’s pretty slick. Definitely worth a look

If you’d like some separation, one option is to create a VM on TrueNAS for PBS that connects to an NFS export where all the data would be stored.

What I did in this scenario is an LXC container running PBS, which uses a bindmount for storage. That bindmount is populated via an NFS export from my NAS, mounted on the PVE host using autofs so that if it disconnects, it will reconnect as soon as it can.

Technetium is a recursive DNS resolver with a nice web UI. If you’re familiar with PiHole or AdGuard Home, you can think of it in that genre, but much more full-featured.

That metadata is written into the photo by the camera, so Immich may not be able to accommodate this easily. Not sure about Canon specifically, but my Nikon cameras have a memory bank for manual focus lenses. Might be worth checking through your menus.

The two pieces of software have very different topologies.

In very broad strokes: Something like FunkWhale uses a server-client model. To get to it, you connect to it remotely and you need some way to get there. By contrast Syncthing behaves as a mesh of nodes. Each node connects directly to the other nodes and the syncthing project folks host relays that help introduce the nodes to one another and penetrate NAT.

No, you may not need a paid domain to use your self-hosted FunkWhale server (I haven’t dabbled with that service in particular). There are a few options.

1. You could probably use the direct public IP address or alternatively
2. Use a dynamic DNS provider (like afraid.org) to resolve your IP address
3. Use a VPN on all of your clients and use local DNS to resolve your FunkWhale server’s local IP address.

These all assume that you have a public IP address on your router and not one that’s being NAT-ed by your ISP.

Again, these are very broad strokes, but hopefully it helps point your in a direction for some research.

There’s definitely nothing magic about ports 443 and 80. The risk is always that the underlying service will provide a vulnerability through which attackers could find a way. Any port presents an opportunity for attack; the security of the service is the is what makes it safe or not.

I’d argue that long tested services like ssh, absent misconfiguration, are at least as safe as most reverse proxies. That doesn’t mean to say that people won’t try to break in via port 22. They sure will—they try on web ports too.

I’m not sure if this what you’re after, but it sounded to me that you were describing monitoring. Might be worth your checking out librenms or zabbix or checkmk. Those would give you a good overview of the health of your stuff and keep track of what’s where.

I’m not familiar with Zurg, but the WebDAV connection makes me recall: doesn’t LXC require that the FUSE kernel module be loaded in order to use WebDAV?

I’ve also seen it recommended that WebDAV be setup on the host and then the mount points bind mounted into the container. Not sure if any of that helps, but maybe it’ll lead you somewhere.

That’s a great tip. I’d completely forgot you can use telnet for that. Thanks!

Thanks for the response. I really should just dive in, but I’ve got this nagging fear that I’m going to forget about some DNS record that will bork my entire mail service. It good to hear about some working instances that people are happy with.

Tainted in that the kernel and ZFS have different licenses. Not a functional impairment. I have no way to check to check a system not using ZFS. For my use case, Debian plus ZFS are PVE’s principal features.

I have synapse server running in docker on a VPS and it’s been pretty reliable. At my office I use it as sort of a self-hosted Slack replacement. For our use case, I don’t have federation enabled, so no experience on that front. It’s a small office and everyone here uses either Element or FuzzyChat on desktop and mobile. It runs behind an nginx reverse proxy and I’ve got SSO set up with Authentik and that’s worked very well. Happy to share some configs if that would be useful.

Have you by any chance documented your PMG set up? I’m also a very happy Mailcow user and spinning up PMG is something I’ve been meaning to tackle for years so I can implement archiving with mailpiler, but I’ve never really wrapped my head around how everything fits together.

Ceph isn’t installed by default (at least it hasn’t been any time I’ve set up PVE) and there’s no need to use ZFS if you don’t want to. It’s available, but you can go right ahead and install the system on LVM instead.

I think you can do the same with LUKS (https://www.cyberciti.biz/hardware/cryptsetup-add-enable-luks-disk-encryption-keyfile-linux/) if that’s your preferred route.

Another idea for you: if you use ZFS for the install, check Debian directions on OpenZFS or zfsbootmenu and you’ll get directions for an encrypted installation. You’ll be able to specify the path to a key file, which you can keep on a thumb drive. When the machine boots up, it’ll see the thumb drive and decrypt the zpool automatically; yank the thumb drive and it won’t (backup the key of course).

The answers for this will vary widely, but the thing I think many people overlook when planning out expenses is a plan to back up the data. Having the file server is great, but start planning now for what to do when it breaks. Where will backup copies of your data live and how will you restore it?

As to the server itself, the hardware completely depends on your desires. Some like second hand enterprise gear; others prefer purpose-made home NAS devices or a DIY rig. On the software side my thought is keep it simple if you’re starting up. There are good readymade options (TrueNAS, XigmaNAS, openmediavault, unraid, etc). They’re all great and they help get up and running quickly. They also have a lot of tempting knobs to turn that can cause unexpected problems if you don’t fully understand them.

To my mind file servers have to be reliable above all else, so I’d avoid running anything besides file sharing on your server until it’s running like a top and then only add more layers one at a time.

Sorry for all the philosophy, but I really do think this is a common stumbling block for people getting started.

You ever see those Wired videos where they talk about a concept on five different levels ranging from beginner to expert?

The first level answer is likely that, yes, you’re reasonably secure in your current setup. That’s true, but it’s also really simplified and it skips a lot of important considerations. (For example, “secure against what?”) One of the first big realizations that hit me after I’d been running servers for a little while and trying to chase security is the idea of a threat model. What protects me from a script kiddie trying to break into one of my web servers won’t do much for me against a phishing attack.

The more you do this, though, the more I think you’ll realize that security is more of a process than an actual state you can attain.

I think it sounds like you’re doing a good job moving cautiously and picking up things at each step. If the next step is remote access, you’ve got a pretty good situation for a mesh VPN like Tailscale or Netbird or ZeroTier. They’ll help you deal with the CGNAT and each one gives you a decent growth path where you can start out with a free tier and if you need it in the future, either buy into the product or self host it.
