linux_dir_file_backup_new

Linux 目录与文件备份 - 无时间戳压缩并强制覆盖同名旧压缩

一键脚本

半交互式

bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/linux_dir_file_backup_new.sh) /源目录 /备份目录

免交互式自动 tar.gz 格式压缩

bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/linux_dir_file_backup_new.sh) /源目录 /备份目录 tar.gz

免交互式自动 zip 格式压缩

bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/linux_dir_file_backup_new.sh) /源目录 /备份目录 zip

功能模式	执行命令	作用说明
传参快速执行（2参数）	`./backup.sh /源目录 /备份目录`	直接指定路径，免交互批量备份全部项目
传参指定格式（3参数）	`./backup.sh /源目录 /备份目录 tar.gz`	额外指定压缩格式（tar.gz / zip）
交互模式	`./backup.sh`	不传参，手动输入目录可视化备份
批量全备份	交互界面输入 `666`	一键备份当前目录所有文件/文件夹
实用示例	`./backup.sh /data /mnt/backup zip`	备份 `/data` 内容到 `/mnt/backup`，格式为 zip
备份规则	-	无时间戳，备份文件同名强制覆盖
支持格式	-	支持 `tar.gz` / `zip` 两种格式
日志记录	-	自动在备份目录的 `logs/` 下生成日志文件

备份目录结构图

./backup.sh /mnt/data /mnt/backup tar.gz

# 源目录（待备份）
/mnt/data
├── project/
├── config/
└── readme.txt

# 备份后（无时间戳·同名覆盖）
/mnt/backup
├── project.tar.gz
├── config.tar.gz
├── readme.txt.tar.gz
└── logs/
    └── 2025-09-11-10-30-00.log

补充说明

该脚本用于交互式或参数化备份目录和文件，采用原名称打包（无时间戳），备份时强制覆盖同名旧压缩文件，适合快速备份项目或配置文件的场景。

功能特点

无时间戳命名：备份文件使用原目录名，方便覆盖更新
交互式操作：支持传参或交互式输入工作目录和备份保存目录
格式参数支持：支持 2 参数（自动 tar.gz）和 3 参数（指定格式）两种传参方式
强制覆盖：同名备份文件自动覆盖，无需手动删除
多格式支持：支持 tar.gz / zip 两种压缩格式
自动日志记录：每次备份自动在 logs/ 目录生成日志文件，记录备份详情、文件大小等信息
人性化显示：压缩文件大小自动转换为可读格式（如 1.2GiB）
彩色输出：全程彩色提示，操作状态清晰可见
智能列表：自动过滤已压缩文件，仅显示可备份项

实例使用方法

# 交互式操作（会提示输入工作目录和备份保存目录）
bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/linux_dir_file_backup_new.sh)

# 直接传参：工作目录 + 备份保存目录 + 指定 tar.gz 格式
bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/linux_dir_file_backup_new.sh) /vol1/1000/compose /vol2/1000/file/myfile/compose/downloads tar.gz

# 直接传参：工作目录 + 备份保存目录 + 指定 zip 格式
bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/linux_dir_file_backup_new.sh) /vol1/1000/compose /vol2/1000/file/myfile/compose/downloads zip

注意事项

备份文件名不带时间戳，多次备份会覆盖旧文件
如需保留历史备份，请手动重命名或改用 linux_dir_file_backup_old.sh
每次备份会自动在备份目录的 logs/ 子目录下生成日志文件（格式：YYYY-MM-DD-HH-MM-SS.log）
备份大目录可能需要较长时间，请耐心等待
确保备份保存目录有足够空间
3 参数模式仅支持 tar.gz 和 zip 两种格式，传入其他格式将报错退出
