-## rclone (Google Drive)
-
-The system has `rclone` installed and a systemd job to sync `/data` to a remote named `gdrive`:
-
-- Service: `rclone-backup.service` (oneshot)
-- Timer: `rclone-backup.timer` (runs daily 03:00)
-- Log: `/var/log/rclone-backup.log`
-
-### 1) Create the remote `gdrive`
-Run on the fileserver:
-
-```bash
-sudo -i
-rclone config
-```
-
-Then:
-- n) New remote
-- name: `gdrive`
-- storage: `drive` (Google Drive)
-- Use auto config? For headless server choose "No"
-  - Follow the printed instructions using another machine, or run on a desktop and copy the token
-- Keep defaults unless you need a service account
-- y) Yes to save
-
-Verify:
-```bash
-rclone lsd gdrive:
-rclone mkdir gdrive:backup-daten
-```
-
-### 2) Test backup manually
-```bash
-sudo systemctl start rclone-backup.service
-sudo journalctl -u rclone-backup -e
-sudo tail -n 100 /var/log/rclone-backup.log
-```
-
-### 3) Check/enable timer
-```bash
-systemctl list-timers '*rclone*'
-sudo systemctl enable --now rclone-backup.timer
-```

----
-
-## SMB password for `danlin`
-
-The share configuration:
-- Protected share: `daten` → requires user `danlin`
-- Guest share: `daten-share` → guest access allowed
-
-Set the Samba password for `danlin` (independent from system login password):
-
-```bash
-sudo smbpasswd -a danlin
-```
-
-Useful commands:
-```bash
-sudo pdbedit -L                   # list Samba users
-sudo systemctl status samba
-sudo journalctl -u samba -e
-```
-
-Access examples:
-- Windows: `\\fileserver\daten` or `\\fileserver\daten-share`
-- macOS Finder: Go → Connect to Server → `smb://fileserver/daten` or `smb://fileserver/daten-share`

-## Troubleshooting
-- rclone auth on headless: use `rclone authorize 'drive'` on a desktop and paste token
-- Permissions: ensure `/data/daten` and `/data/daten/share` exist and are writable (`systemd-tmpfiles` creates them)
-- Firewall: SMB ports 139/445 are open by module config
