Immich Album Downloader

This Python script downloads all assets (photos/videos) from a specific album in your Immich instance, using its API. It supports resuming by skipping files that already exist locally.

Features

• Downloads all assets from a specified album
• Uses pagination to handle large albums
• Skips already-downloaded files
• Can be automated with systemd services and timers

Requirements

You can install dependencies with:

pip install requests

or you can use your system's package manager.

Running the script automatically

Create a service file at /etc/systemd/user/immich-album-downloader.service:

[Unit]
Description=Immich Album Downloader
After=network.target

[Service]
Type=simple
EnvironmentFile=/opt/immich-album-downloader/.env
ExecStart=/usr/bin/python3 /opt/immich-album-downloader/main.py
Restart=no

[Install]
WantedBy=default.target

Enable and start the service (only if you don't configure the timer below):

systemctl --user daemon-reload
systemctl --user enable --now immich-album-downloader.service

---

Running the script periodically

To run the download periodically, create /etc/systemd/user/immich-album-downloader.timer:

[Unit]
Description=Download an Immich album periodically

[Timer]
OnBootSec=15m
OnUnitActiveSec=6h

[Install]
WantedBy=timers.target

Enable the timer:

systemctl --user enable --now immich-album-downloader.timer

This will trigger the album download 15 minutes after boot and then every 6 hours.
