# Backup CLI Migration Summary

## ✅ **Completed Migration**

Successfully migrated from shell scripts to Cobra CLI application for database backup and restore operations.

### **What Changed**

#### **Removed**
- ❌ `scripts/backup-db.sh` - Shell script deleted
- ❌ `scripts/restore-db.sh` - Shell script deleted

#### **Created**
- ✅ `cmd/backup/main.go` - Cobra CLI application
- ✅ `cmd/backup/README.md` - CLI documentation

#### **Updated**
- ✅ `Makefile` - Updated backup/restore commands
- ✅ `TESTING.md` - Updated backup documentation
- ✅ `TEST_ISOLATION.md` - Updated backup documentation
- ✅ `README.md` - Added backup CLI section

### **New Cobra CLI Features**

#### **Multiple Connection Sources**

1. **Dev Mode** (`--dev`):
   ```bash
   go run ./cmd/backup --dev
   ```
   - Uses Docker Compose configuration
   - localhost:5432, turash/turash123

2. **Environment Variables** (default):
   ```bash
   go run ./cmd/backup
   ```
   - Uses `pkg/config` environment variables
   - POSTGRES_HOST, POSTGRES_USER, etc.

3. **Connection String** (`--conn`):
   ```bash
   go run ./cmd/backup --conn "postgres://user:pass@host:port/db"
   ```
   - Direct PostgreSQL connection string

#### **Backup Command**

```bash
# Basic usage
go run ./cmd/backup --dev

# With options
go run ./cmd/backup --dev --dir /custom/path --keep 20
```

**Features**:
- ✅ Timestamped backups
- ✅ Gzip compression
- ✅ Automatic cleanup (keeps last N backups)
- ✅ Lists recent backups
- ✅ Connection validation

#### **Restore Command**

```bash
go run ./cmd/backup restore backups/turash_backup_20250124_120000.sql.gz --dev
```

**Safety Features**:
- ✅ Confirmation prompt
- ✅ Automatic safety backup before restore
- ✅ Error recovery with safety backup path

### **Makefile Integration**

```bash
# Backup commands
make db-backup              # Dev mode
make db-backup-env          # Environment variables
make db-backup-conn CONN=... # Connection string

# Restore command
make db-restore BACKUP=backups/file.sql.gz
```

### **Benefits of Cobra CLI**

1. ✅ **Cross-platform**: Works on Windows, macOS, Linux
2. ✅ **Type-safe**: Go-based, no shell script quirks
3. ✅ **Flexible**: Multiple connection sources
4. ✅ **Maintainable**: Single codebase, easier to extend
5. ✅ **Integrated**: Part of the Go project, versioned with code
6. ✅ **Helpful**: Built-in help and documentation

### **Usage Examples**

#### **Development**

```bash
# Quick backup before changes
make db-backup

# Custom backup location
go run ./cmd/backup --dev --dir ~/backups/turash
```

#### **Production**

```bash
# Backup production database
go run ./cmd/backup --conn "postgres://prod_user:prod_pass@prod_host:5432/turash_prod"

# Restore production database
go run ./cmd/backup restore backup.sql.gz --conn "postgres://prod_user:prod_pass@prod_host:5432/turash_prod"
```

#### **CI/CD**

```bash
# Backup before deployment
go run ./cmd/backup --conn "$DATABASE_URL" --dir /backups

# Automated backup retention
go run ./cmd/backup --conn "$DATABASE_URL" --keep 30
```

### **Migration Checklist**

- ✅ Shell scripts deleted
- ✅ Cobra CLI implemented
- ✅ Backup functionality working
- ✅ Restore functionality working
- ✅ Makefile updated
- ✅ Documentation updated
- ✅ Tested with dev mode
- ✅ Multiple connection sources supported

### **Next Steps**

1. Build binary for production use:
   ```bash
   go build -o bin/backup ./cmd/backup
   ```

2. Add to CI/CD pipeline for automated backups

3. Schedule regular backups (cron/systemd timer)

4. Consider adding backup verification/validation
