linux里某个文件目录备份

#!/bin/bash

# 定义源目录和目标目录
SOURCE_DIR="/path/to/source"
BACKUP_DIR="/path/to/backup"
DATE=$(date +%Y%m%d%H%M%S)

# 创建备份目录（如果不存在）
mkdir -p $BACKUP_DIR

# 执行备份
tar -czf $BACKUP_DIR/backup_$DATE.tar.gz $SOURCE_DIR

# 输出备份完成信息
echo "Backup completed: $BACKUP_DIR/backup_$DATE.tar.gz"

#!/bin/bash

# 定义源目录和目标目录
SOURCE_DIR="/path/to/source"
BACKUP_DIR="/path/to/backup"
LAST_BACKUP=$(ls -t $BACKUP_DIR/*.tar.gz | head -1)

# 创建新的备份目录
NEW_BACKUP_DIR="$BACKUP_DIR/$(date +%Y%m%d%H%M%S)"
mkdir -p $NEW_BACKUP_DIR

# 使用rsync进行增量同步
rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} $SOURCE_DIR/ $NEW_BACKUP_DIR/

# 压缩备份目录
tar -czf $NEW_BACKUP_DIR.tar.gz -C $NEW_BACKUP_DIR .

# 清理临时目录
rm -rf $NEW_BACKUP_DIR

# 输出备份完成信息
echo "Incremental backup completed: $BACKUP_DIR/$(basename $NEW_BACKUP_DIR.tar.gz)"
