# Configuration Reference
BackupX loads `./config.yaml` from the working directory by default. You can override the path with `--config`. Every key can also be set via a `BACKUPX_` prefixed environment variable.
## Full config reference
```yaml title="config.yaml"
server:
host: "0.0.0.0" # BACKUPX_SERVER_HOST
port: 8340 # BACKUPX_SERVER_PORT
mode: "release" # release | debug
external_url: "" # BACKUPX_SERVER_EXTERNAL_URL — public Master URL for Agent install scripts
database:
path: "./data/backupx.db" # BACKUPX_DATABASE_PATH — embedded SQLite
security:
jwt_secret: "" # BACKUPX_SECURITY_JWT_SECRET — auto-generated if empty
jwt_expire: "24h" # BACKUPX_SECURITY_JWT_EXPIRE
encryption_key: "" # AES-256-GCM key for storage config encryption
backup:
temp_dir: "/tmp/backupx" # BACKUPX_BACKUP_TEMP_DIR
max_concurrent: 2 # BACKUPX_BACKUP_MAX_CONCURRENT
retries: 3 # Per-upload rclone low-level retries
bandwidth_limit: "" # e.g. "10M" to cap transfers at 10 MB/s
log:
level: "info" # debug | info | warn | error
file: "./data/backupx.log"
```
## Secret generation
If `jwt_secret` or `encryption_key` is empty on first start, BackupX generates a random value and persists it to the `system_configs` table. Keep a backup of `data/backupx.db` — losing it invalidates all existing encrypted storage configurations.
## Environment variables
The environment wins when both file and env are set. All dot-paths become underscores and uppercase:
| Config key | Env variable |
|------------|--------------|
| `server.port` | `BACKUPX_SERVER_PORT` |
| `server.external_url` | `BACKUPX_SERVER_EXTERNAL_URL` |
| `security.jwt_expire` | `BACKUPX_SECURITY_JWT_EXPIRE` |
| `log.level` | `BACKUPX_LOG_LEVEL` |
| `backup.max_concurrent` | `BACKUPX_BACKUP_MAX_CONCURRENT` |
| `backup.temp_dir` | `BACKUPX_BACKUP_TEMP_DIR` |
| `backup.bandwidth_limit` | `BACKUPX_BACKUP_BANDWIDTH_LIMIT` |
## Master external URL
Set `server.external_url` when BackupX is behind Docker, Nginx, a load balancer, or any reverse proxy whose internal Host is not reachable by remote Agents:
```yaml
server:
external_url: "https://backup.example.com"
```
This value is used when BackupX renders one-click Agent install scripts and docker-compose snippets. It must be reachable from every Agent host. Leave it empty only when `X-Forwarded-Proto` / `X-Forwarded-Host` are reliable and point to the same URL that Agents can access.
