两台机器都设置为 `BACKUP` + `nopreempt`（禁用抢占模式），由 priority 决定谁为主：

state BACKUP # 两台都设为 BACKUP

BACKUP_DIR="/etc/nginx/backups/$(date +%Y%m%d_%H%M%S)"

mkdir -p $BACKUP_DIR

cp -r $NGINX_CONF_DIR/* $BACKUP_DIR/

- 备节点（Backup）监听广播，主节点失联（3 次未收到广播）时自动接管 VIP

| state | MASTER | BACKUP | 初始状态，最终由 priority 决定 |

state BACKUP

Backup: 无 VIP + Nginx 待命

Master: check_nginx 脚本返回非 0 → priority -= weight → priority < Backup

- 新增标签：redis, database, persistence, backup, data-loss

- Created raw: raw/articles/redis-rdb-aof-backup-strategy.md

- Created concepts: redis-persistence-strategy, redis-backup-recovery

- Updated: redis-backup-recovery, redis-connection-management

- redis-backup-recovery: +2（→ redis-persistence-strategy, redis-memory-optimization）
