每天定时备份

#!/bin/bash

# 设置备份目录
BACKUP_DIR="/home/zjl/etcd/backup"

# 获取当前日期作为备份文件名的一部分
DATE=$(date +%Y%m%d)

# 检查备份目录是否存在，不存在则创建
if [ ! -d "$BACKUP_DIR" ]; then
    mkdir -p "$BACKUP_DIR"
fi

# 执行etcd备份命令，将备份文件保存到指定目录并以当天日期命名
etcdctl snapshot save "${BACKUP_DIR}/apisix-etcd-${DATE}.db"

# 输出备份完成信息
echo "etcd backup completed on $(date) and saved as apisix-etcd-${DATE}.db in ${BACKUP_DIR}"
