## Operations ## Operations
### Monitoring ### Monitoring
Uptime Kuma monitors the kopia service: monitor.url: tcp://kopia:51515 Kuma monitors are available for this service:
```bash ```bash
docker stack services kopia docker stack services kopia
docker service logs -f kopia
``` ```
### Backups ### Backups
Critical backups are stored in /DockerVol/kopia/config and /DockerVol/kopia/cache. Reconstructable backups are stored in /DockerVol/kopia/cert. Critical backups are stored in the `/DockerVol/kopia/config` volume. Non-critical backups can be restored from the `/DockerVol/kopia/cache` volume.
### Restore ### Restore

## Common Failures ## Common Failures
| Failure Mode | Symptoms | Cause | Fix | 1. **Service not available**: Check if Caddy is running and configured correctly.
|-------------|----------|-------|------| 2. **Incorrect environment variables**: Verify that all environment variables are set correctly in the `env` section of the YAML file.
1. Service not available | Docker service is not running | No services defined for kopia | Check the deploy script and ensure that all required services are defined. 3. **Volume issues**: Ensure that all volumes are properly mounted and accessible.
2. Caddy reverse proxy fails to start | Caddy service does not start | Insufficient permissions or incorrect configuration | Review the Caddy configuration and ensure that it matches the .env file. 4. **Network connectivity**: Verify that the service can connect to the network and other services.
3. Uptime Kuma monitoring fails | Kuma service does not detect kopia service | Inadequate monitoring configuration | Review the kuma configuration and ensure that it matches the monitor.url defined in the stack.
