## Quick Start

### 1. Install

**Docker (recommended, no clone needed):**

```bash
# Create a docker-compose.yml then start
docker compose up -d

# Or run directly
docker run -d --name backupx -p 8340:8340 -v backupx-data:/app/data awuqing/backupx:latest
```

> Docker Hub: [`awuqing/backupx`](https://hub.docker.com/r/awuqing/backupx) — supports linux/amd64 and linux/arm64.

<details>
<summary>docker-compose.yml reference</summary>

```yaml
services:
  backupx:
    image: awuqing/backupx:latest
    container_name: backupx
    restart: unless-stopped
    ports:
      - "8340:8340"
    volumes:
      - backupx-data:/app/data
      # Mount host directories to back up (add as needed):
      # - /var/www:/mnt/www:ro
      # - /etc/nginx:/mnt/nginx-conf:ro
    environment:
      - TZ=Asia/Shanghai

volumes:
  backupx-data:
```

</details>

**Pre-built binaries (bare metal):**

Download from [Releases](https://github.com/Awuqing/BackupX/releases):

```bash
tar xzf backupx-v*-linux-amd64.tar.gz && cd backupx-*
sudo ./install.sh        # Auto-configures systemd + Nginx
```

**Build from source:**

```bash
git clone https://github.com/Awuqing/BackupX.git && cd BackupX
make build               # Build frontend + backend
make docker-cn           # Or Docker build with China mirrors (goproxy.cn / npmmirror / Aliyun apk)
```

### 2. Open the Console

Visit `http://your-server:8340` in your browser. First-time access guides you through admin account creation.

### 3. Add a Storage Target

Go to **Storage Targets** → **Add**, choose a storage type and enter credentials:

| Storage Type | Required Fields |
|-------------|----------------|
| Alibaba Cloud OSS | Region + AccessKey ID/Secret + Bucket |
| Tencent Cloud COS | Region + SecretId/SecretKey + Bucket (`name-appid`) |
| Qiniu Cloud Kodo | Region + AccessKey/SecretKey + Bucket |
| S3 Compatible | Endpoint + AccessKey + Bucket |
| Google Drive | Client ID/Secret → click Authorize for OAuth |
| WebDAV | Server URL + Username/Password |
| FTP | Host + Port + Username/Password |
| Local Disk | Target directory path |
| SFTP / Azure / Dropbox / OneDrive etc. | Select the type, fill in required fields; advanced options are collapsible |

> For Chinese cloud providers, just enter Region and AccessKey — the system auto-assembles the Endpoint. Rclone-type configs separate required fields from optional advanced options (collapsed by default).

Click **Test Connection** to verify.

### 4. Create a Backup Task

Go to **Backup Tasks** → **Create**, complete 3 steps:

1. **Basic Info** — Task name, backup type, Cron expression (leave empty for manual-only)
2. **Source Config** — File backup: select source paths (supports multiple); Database: enter connection info
3. **Storage & Policy** — Select storage target(s) (supports multiple), compression, retention days, encryption toggle

Save, then click **Run Now** to test. View real-time logs in **Backup Records**.

> Deleting a backup task automatically cleans up remote storage files while preserving backup records for audit purposes.

### 5. Set Up Notifications (Optional)

Go to **Notifications** to configure Email, Webhook, or Telegram alerts for backup success/failure.

---

## Deployment Guide

### Docker

```bash
docker compose up -d     # Using the docker-compose.yml above
```

Mount host directories for file backup (add to `volumes` in docker-compose.yml):

```yaml
volumes:
  - backupx-data:/app/data
  - /var/www:/mnt/www:ro
  - /etc/nginx:/mnt/nginx-conf:ro
```

Override config via environment variables:

```yaml
environment:
  - TZ=Asia/Shanghai
  - BACKUPX_LOG_LEVEL=debug
  - BACKUPX_BACKUP_MAX_CONCURRENT=4
```

To upgrade: go to **System Settings**, click "Check for Updates" to see if a new version is available, then run `docker compose pull && docker compose up -d`.

### Bare Metal

```bash
# From pre-built package
tar xzf backupx-v*-linux-amd64.tar.gz && cd backupx-*
sudo ./install.sh

# Or from source
make build
sudo ./deploy/install.sh
```

The install script creates a system user, installs to `/opt/backupx/`, configures systemd, and sets up Nginx reverse proxy.

### Nginx Reverse Proxy (bare metal)

```nginx
server {
    listen 80;
    server_name backup.example.com;

    location / {
        root /opt/backupx/web;
        try_files $uri $uri/ /index.html;
    }

    location /api/ {
        proxy_pass http://127.0.0.1:8340;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}
```

### Configuration

Config file: `./config.yaml` (or override with `BACKUPX_` prefixed env vars):

```yaml
server:
  port: 8340
database:
  path: "./data/backupx.db"
security:
  jwt_secret: ""          # Auto-generated and persisted to DB
  encryption_key: ""      # Auto-generated
backup:
  temp_dir: "/tmp/backupx"
  max_concurrent: 2
log:
  level: "info"           # debug | info | warn | error
  file: "./data/backupx.log"
```

### Password Reset

```bash
# Bare metal
./backupx reset-password --username admin --password newpass123

# Docker
docker exec -it backupx /app/bin/backupx reset-password --username admin --password newpass123
```

## SAP HANA Support

BackupX offers two SAP HANA backup modes — pick whichever fits:

### Mode 1: hdbsql Runner (Web-console managed)

Create a SAP HANA backup task in the Web console. The backend runs `hdbsql` to perform backups, suitable for BackupX-scheduled recurring jobs.

**Source configuration supports:**

| Field | Options | Description |
|-------|---------|-------------|
| Backup type | `data` / `log` | Data or log backup |
| Backup level | `full` / `incremental` / `differential` | Auto-disabled for log backups |
| Parallel channels | `1 ~ 32` | `BACKUP DATA USING FILE ('c1','c2',...)` parallel paths |
| Retry count | `1 ~ 10` | Exponential backoff (5s × attempt²) |
| Instance number | Optional | Inferred from port or manually specified |

### Mode 2: Backint Protocol Agent (HANA native)

BackupX ships a built-in Backint Agent. SAP HANA calls it via native `BACKUP DATA USING BACKINT` syntax, and data is routed automatically to BackupX storage targets (S3 / OSS / COS / WebDAV / 70+ backends).

**1. Prepare parameter file** `/opt/backupx/backint_params.ini`:

```ini
#STORAGE_TYPE = s3
#STORAGE_CONFIG_JSON = /opt/backupx/storage.json
#PARALLEL_FACTOR = 4
#COMPRESS = true
#KEY_PREFIX = hana-backup
#CATALOG_DB = /opt/backupx/backint_catalog.db
#LOG_FILE = /var/log/backupx/backint.log
```

**2. Prepare storage config** `/opt/backupx/storage.json` (same schema as BackupX storage targets):

```json
{
  "endpoint": "https://s3.amazonaws.com",
  "region": "us-east-1",
  "bucket": "hana-prod",
  "accessKeyId": "AKIA...",
  "secretAccessKey": "..."
}
```

**3. Create the hdbbackint symlink:**

```bash
ln -s /opt/backupx/backupx /usr/sap/<SID>/SYS/global/hdb/opt/hdbbackint
```

**4. Enable in HANA `global.ini`:**

```ini
[backup]
data_backup_using_backint = true
catalog_backup_using_backint = true
log_backup_using_backint = true
data_backup_parameter_file = /opt/backupx/backint_params.ini
log_backup_parameter_file = /opt/backupx/backint_params.ini
```

**5. Manual CLI invocation (for troubleshooting):**

```bash
backupx backint -f backup  -i input.txt -o output.txt -p backint_params.ini
backupx backint -f restore -i input.txt -o output.txt -p backint_params.ini
backupx backint -f inquire -i input.txt -o output.txt -p backint_params.ini
backupx backint -f delete  -i input.txt -o output.txt -p backint_params.ini
```

The Backint Agent maintains an `EBID ↔ object-key` catalog in a local SQLite DB. All operations follow the SAP HANA Backint protocol (`#PIPE` / `#SAVED` / `#RESTORED` / `#BACKUP` / `#NOTFOUND` / `#DELETED` / `#ERROR`).

## Multi-Node Cluster

BackupX supports Master-Agent mode for managing multiple servers:

1. Web Console → **Node Management** → **Add Node** — system generates a Token
2. Deploy Agent on remote server, connect using the Token
3. Create backup tasks and assign to specific nodes — Master dispatches automatically

- Local node auto-detects IP address and version
- Remote nodes report system info via Agent heartbeat (hostname, IP, OS, architecture, version)
- Node names can be edited directly from the console
- Visual directory browser lets you pick directories on remote Agent nodes
