# Backup & Restore Guide

## What gets backed up

| File | Contents |
|------|----------|
| `postgres.dump` | Full PostgreSQL database (pg_dump custom format) |
| `api-uploads.tar.gz` | User-uploaded files (vehicle images, documents, etc.) |
| `traefik-letsencrypt.tar.gz` | Let's Encrypt SSL certificates |
| `volumes/` | Raw Docker volume archives (Redis, pgmanage, etc.) |
| `manifest.txt` | Backup metadata (timestamp, project name) |

> **Note:** The `.env.docker.production` file is NOT included in backups. Store it separately in a secure location (password manager, encrypted storage). You will need it to restore on a new server.

---

## Running a Backup

```bash
cd ~/car_management_system

# Default — saves to ./backups/<timestamp>/
bash scripts/docker-prod-backup.sh

# Custom backup directory
bash scripts/docker-prod-backup.sh /mnt/external/backups
```

The script will create a timestamped directory, e.g.:
```
backups/rentaldrivego-prod-20260522T103000Z/
```

PostgreSQL does not need to be stopped. The script brings it up automatically if needed.

---

## Running a Restore

> **Warning:** Restore is destructive. It will overwrite the current database and uploaded files.

```bash
cd ~/car_management_system

bash scripts/docker-prod-restore.sh backups/rentaldrivego-prod-<timestamp> --yes
```

The `--yes` flag is required. Without it, the script exits with instructions.

### What the restore does (in order)

1. Stops all app services (api, dashboard, marketplace, admin, pgmanage, redis, traefik)
2. Starts PostgreSQL
3. Restores the database with `pg_restore --clean --if-exists`
4. Restores uploaded files into the api_uploads volume
5. Restores Traefik SSL certificates
6. Restores remaining Docker volumes (Redis, pgmanage)
7. Starts all services back up

---

## Automated Daily Backups (cron)

To schedule a daily backup at 3:00 AM:

```bash
(crontab -l 2>/dev/null; echo '0 3 * * * cd /root/car_management_system && bash scripts/docker-prod-backup.sh /root/car_management_system/backups >> /var/log/rentaldrivego-backup.log 2>&1') | crontab -
```

Verify the cron job was added:
```bash
crontab -l
```

### Cleaning up old backups

To keep only the last 7 days of backups, add a cleanup job:

```bash
(crontab -l 2>/dev/null; echo '30 3 * * * find /root/car_management_system/backups -maxdepth 1 -name "rentaldrivego-prod-*" -mtime +7 -exec rm -rf {} +') | crontab -
```

---

## Restoring on a Fresh Server

1. Install Docker and Docker Compose on the new server
2. Clone the repository
3. Recreate `.env.docker.production` (from your secure backup of that file)
4. Copy the backup directory to the new server
5. Run the restore script:
   ```bash
   bash scripts/docker-prod-restore.sh /path/to/backup --yes
   ```

---

## Verifying a Backup

Check the backup directory contents and sizes:

```bash
ls -lh backups/rentaldrivego-prod-<timestamp>/
cat backups/rentaldrivego-prod-<timestamp>/manifest.txt
```

Test that the database dump is valid:

```bash
pg_restore --list backups/rentaldrivego-prod-<timestamp>/postgres.dump | head -20
```
