一键部署OpenClaw 网站备份是出事之后最后悔没做的东西。很多人服务器被黑后才发现数据库没备份，几年的内容一夜归零。 (ECNS) -- China Central Depository & Clearing Co., Ltd. (CCDC) supported Shanghai Electric Group Global Investment Ltd., a wholly owned overseas subsidiary of Shanghai Electric Group Co., Ltd., in issuing 1.5 billion yuan (about $209 million) in pilot free trade zone (FTZ) offshore bonds on Wednesday. The three-year bonds carry a coupon rate of 1.8%. The issuance set several records: it is the world's first corporate FTZ offshore bond, the first FTZ offshore bond to be listed on the Hong Kong Stock Exchange, and the largest single-tranche FTZ offshore bond issuance to date. The bonds attracted strong interest from investors in Hong Kong, Macao, Southeast Asia, the Middle East and Europe. The issuance marks a significant step forward in the development of the FTZ offshore bond market, broadening the issuer base from financial institutions to high-quality corporate entities while further diversifying market participants and product offerings.

二 | 其实一个shell脚本加一个定时任务就能解决。 下面这个脚本同时备份MySQL数据库和网站源码，按日期命名，保留最近7天。Linux服务器直接放到/root/backup.sh，Windows可以改成PowerShell版本，或者把Linux脚本放在宝塔面板的Shell终端里执行。
#!/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 {} \;
三 | 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
