# 本机 → 服务器 rsync 回退部署（当服务器 git pull 超时/失败时使用）
# ============================================
# 使用方法（在项目根目录执行）：
#   export RSYNC_DEPLOY_PASSWORD='你的SSH密码'   # 同 DEPLOY_QUICK.md 部署凭据
#   bash backend/deploy/deploy-rsync-from-local.sh
# 或一行（密码同部署凭据）：
#   RSYNC_DEPLOY_PASSWORD='yangyichenYANGYICHENkaifa859' bash backend/deploy/deploy-rsync-from-local.sh
# ============================================
# 会做：rsync backend/ 到服务器（--delete），再在服务器执行 install/prisma/build/pm2 重启。
