I use the first option, but with the addition of using an LVM snapshot to guarantee that the database (or anything else in the backup) isn’t changed while taking the backup.

Getting a domain name may not be enough, if you don’t have a static IP you’ll still need a DDNS service.
What do you get for the paid no-ip service? Is it just a nice subdomain? You can get a custom domain and use a CNAME record to point one or more subdomains to a free DDNS subdomain.

I followed the guide found here, however with a few modifications.
Notably, I did not encrypt the borg repository, and heavily modified the backup script.
#!/bin/bash -ue
# The udev rule is not terribly accurate and may trigger our service before
# the kernel has finished probing partitions. Sleep for a bit to ensure
# the kernel is done.
#
# This can be avoided by using a more precise udev rule, e.g. matching
# a specific hardware path and partition.
sleep 5

do
if grep --quiet --fixed-strings $uuid $DISKS; then
break

if [ ! $uuid ]; then
echo "No backup disk found, exiting"
exit 0

echo "Disk $uuid is a backup disk"

Most of my services are stored on individual LVM volumes, all mounted under /mnt
, so immich is completely self-contained under /mnt/photos/immich/
. The last line of my script sends a notification to my phone using ntfy.
Here are a few more details of my setup:
Components:
custom.domain
)The home router has WireGuard port forwarded to server, with no re-mapping (I’m using the default 51820). It’s also providing DHCP services to my home network, using the 192.168.1.0/24 network.
The server is running the dynamic DNS client (keeping the dynamic domain name updated to my public IP), and I have a CNAME record on the vpn.custom.domain
pointing to the dynamic DNS name (which is an awful random string of characters). I also have server.custom.domain
with an A record pointing to 10.30.0.1
. All my DNS records are in public DNS (so no need to change the DNS settings on the computer or phone or use DNS overrides with WireGuard.)
Immich config:
version: "3.8"
services:
immich-server:
container_name: immich_server
image: ghcr.io/immich-app/immich-server:release
entrypoint: ["/bin/sh", "./start-server.sh"]
volumes:
- ${UPLOAD_LOCATION}:/usr/src/app/upload
env_file:
- .env
ports:
- target: 3001
published: 2283
host_ip: 10.30.0.1
depends_on:
- redis
- database
restart: always
networks:
- immich
WireGuard is configured using wg-quick
(/etc/wireguard/wg0.conf
):
[Interface]
Address = 10.30.0.1/16
PrivateKey =
ListenPort = 51820
[Peer]
PublicKey =
AllowedIPs = 10.30.0.12/32
[Peer]
PublicKey =
AllowedIPs = 10.30.0.11/32
Start WireGuard with systemctl enable --now wg-quick@wg0
.
Phone WireGuard configuration (iOS):
[Interface]
Name = vpn.custom.domain
Private Key =
Public Key =

Listen port =

Allowed IPs = 10.30.0.0/16
Persistent Keepalive = 25
[On Demand Activation]
Cellular = On
Wi-Fi = On
SSIDs = Any SSID
This connection is then left always enabled, and comes on whenever my phone has any kind of network connection.
My laptop (running Linux), is also using wg-quick
(/etc/wireguard/wg0.conf):
[Interface]

Endpoint = vpn.custom.domain:51820

My wife’s window’s laptop is configured using the official WireGuard windows app, with similar settings.
No matter where we are (at home, on a WiFi hotspot, or using cellular data) we access Immich over the VPN: http://server.custom.comain:2283/.
Let me know if you have any further questions.
If you want to change the name of the directory without breaking your volumes (or running services, etc), you can specify the name of the project inside the compose file
It saves into the tiddlywiki HTML file. The default behaviour is to then trigger the browser to download the file. You can absolutely store it in a git repository.
TiddlyWiki might be a good option. Technically it’s a wiki, but it is a single HTML page with all functionality built in JavaScript, you could host it on GH pages, though you wouldn’t be able to use its save feature there (you would have to save to your local machine and the deploy a new version). It stores text in little (or large) cards which can be given a title, tags and other metadata, and it providesa full search system.
The peer range shouldn’t be your LAN, it should be a new network range, just for WireGaurd. Make sure that the server running Immich is part of the WireGaurd network.
My phone and laptop see three networks: the internet, the lan (192.168.1.0/24, typically) and WireGaurd (10.30.0.0/16). I can anonymize and share my WireGaurd config if that would help.
I use WireGaurd, it’s set to on demand for any network or cellular data (so effectively always on), no DNS records (I just use public DNS providing private range IP addresses). It doesn’t make any sort of dent in my battery life. Also, only the wiregaurd network traffic is routed through it, so if my server is down the phone/laptop’s internet continues to work. I borrowed my wife’s phone and laptop for 15 minutes to set it up, and now no one has to think about it.
If you’re seeing an OOM killer messsage note that it doesn’t necessarily kill the problem process, by default the kernel hands out memory upon requestt, regardless of whether it has ram to back the allocation. When a process then writes to the memory (at some later time) and the kernel determines that there is no physical ram to store that write, it then invokes OOM Killer. This then selects a process and kills it. MySQL (and MariaDB) use large quantities of ram for cache, and by default the kernel lies about how much is available, so they often end up using more than the system can handle.
If you have many databases in containers, set memory limits for those containers, that should make all the databases play nicer together. Additionally , you may want to disable overcommit
in the kernel, this will cause the kernel to return out of memory to a process attempting to allocate ram and stop lying about free ram to processes that ask, often greatly increasing stability.
I backup to a external hard disk that I keep in a fireproof and water resistant safe at home. Each service has its own LVM volume which I snapshot and then backup the snapshots with borg, all into one repository. The backup is triggered by a udev rule so it happens automatically when I plug the drive in; the backup script uses ntfy.sh (running locally) to let me know when it is finished so I can put the drive back in the safe. I can share the script later, if anyone is interested.
It’s been added recently, in the form of External Libraries.
I did not know that, last I looked it was still in development, I believe.
Something that LVM supports but ZFS and BTRFS don’t, is the ability to reduce your storage. (That is, to empty and remove a drive from the array, without having to completely destroy the storage array.) As a home user without sufficient storage to have complete duplicates of everything, I find this an important feature.
I know it’s not ideal, but if you can afford it, you could rent a VPS in a cloud provider for a week or two, and do the download from Google Takeout on that, and then use sync or similar to copy the files to your own server.
