备份策略（数据库/代码/文件）设计

#!/bin/bash
# 每天晚上11点执行备份
BACKUP_DIR="/path/to/backup/directory"
DATE=$(date +"%Y%m%d")
DB_USER="your_username"
DB_PASS="your_password"
DB_NAME="your_database_name"

# 创建备份目录
mkdir -p $BACKUP_DIR/$DATE

# 执行备份
mysqldump -u $DB_USER -p$DB_PASS $DB_NAME > $BACKUP_DIR/$DATE/$DB_NAME.sql

# 压缩备份文件
gzip $BACKUP_DIR/$DATE/$DB_NAME.sql

# 删除30天前的备份
find $BACKUP_DIR -type d -mtime +30 -exec rm -rf {} \;

#!/bin/bash
# 备份Git仓库到外部存储
REPO_DIR="/path/to/your/repo"
BACKUP_DIR="/path/to/backup/directory"
DATE=$(date +"%Y%m%d")

# 克隆仓库到备份目录
git clone $REPO_DIR $BACKUP_DIR/$DATE

# 压缩备份
tar -czf $BACKUP_DIR/$DATE/repo_backup.tar.gz -C $BACKUP_DIR/$DATE .

# 删除备份目录
rm -rf $BACKUP_DIR/$DATE

# 删除30天前的备份
find $BACKUP_DIR -type f -mtime +30 -exec rm {} \;

#!/bin/bash
# 备份重要文件到云存储
SOURCE_DIR="/path/to/important/files"
BACKUP_DIR="/path/to/backup/directory"
DATE=$(date +"%Y%m%d")

# 创建备份目录
mkdir -p $BACKUP_DIR/$DATE

# 复制文件到备份目录
cp -r $SOURCE_DIR/* $BACKUP_DIR/$DATE/

# 压缩备份
tar -czf $BACKUP_DIR/$DATE/files_backup.tar.gz -C $BACKUP_DIR/$DATE .

# 删除备份目录
rm -rf $BACKUP_DIR/$DATE

# 上传到云存储（这里假设使用了rclone）
rclone copy $BACKUP_DIR/$DATE/files_backup.tar.gz remote:$BACKUP_DIR/$DATE/

# 删除30天前的备份
find $BACKUP_DIR -type f -mtime +30 -exec rm {} \;
