# ============================================
# 完整系统备份脚本 (PowerShell)
# ============================================
# 功能：
#   - 备份 PostgreSQL 数据库
#   - 备份 MinIO 文件存储
#   - 备份关键配置文件 (.env, docker-compose*.yml, prisma/schema.prisma)
#   - 生成本次完整备份的清单 (manifest)
#   - 自动清理过期备份（默认保留 7 天）
# 使用：
#   .\scripts\backup-all.ps1 [-BackupRoot ".\backups\full"] [-RetentionDays 7]
# ============================================
