网站数据自动备份：一个脚本+一个计划任务搞定_我的网站

A |     (ECNS) -- The 2026 Green Computing Power Conference opened Saturday in Hohhot, Inner Mongolia Autonomous Region, with 13 projects worth 136.1 billion yuan ($18.85 billion) signed across Hohhot and Ulanqab.    More than 500 participants attended the event, which showcased pilot achievements in AI application scenarios and green power infrastructure.         Organizers said the projects span the full computing power chain — from chip testing and hardware supply to data center coordination and downstream applications such as token trading and real world AI use cases.    (By Helen Mo & intern Xu Wenda)                    。

#!/bin/bash
SITE_DIR="/www/wwwroot/yoursite"
DB_NAME="yourdb"
DB_USER="root"
DB_PASS="yourpass"
BACKUP_DIR="/backup/$(date +%Y%m%d)"
 
mkdir -p $BACKUP_DIR
 
# 备份数据库
mysqldump -u$DB_USER -p$DB_PASS --single-transaction $DB_NAME | gzip > $BACKUP_DIR/db.sql.gz
 
# 备份网站文件
tar -czf $BACKUP_DIR/files.tar.gz -C $(dirname $SITE_DIR) $(basename $SITE_DIR)
 
# 删除7天前的备份
find /backup -maxdepth 1 -type d -mtime +7 -exec rm -rf {} \;

    脚本写好之后加一条crontab，每天凌晨3点执行。备份文件建议再同步一份到对象存储，比如阿里云OSS或腾讯云COS，做到异地容灾。    # crontab -e    0 3 * * * /bin/bash /root/backup.sh >> /var/log/backup.log 2>&1    数据来源：MySQL Reference Manual 8.0（mysqldump），Linux crontab官方文档
