linux_dir_file_backup_sep

Linux 目录与文件备份 - 单个文件独立打包到时间戳目录，自动保留 7 份历史

一键脚本

半交互式

bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/linux_dir_file_backup_sep.sh) /源目录 /备份根目录

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_sep.sh) /源目录 /备份根目录 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_sep.sh) /源目录 /备份根目录 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 /备份根目录`	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 /备份根目录 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/www /mnt/backup zip`	备份 `/data/www` 内项目到 `/mnt/backup`，格式为 zip
备份规则	-	时间戳目录内独立打包，每个源文件/目录单独生成 `xxx.zip`，日志同目录
历史清理	-	自动保留最近 7 份备份，超出删除最早目录
支持格式	-	支持 `tar.gz` / `zip` 两种格式
日志记录	-	自动在本次备份目录内生成 `.log` 日志文件

补充说明

该脚本用于交互式或参数化备份目录和文件，每个源文件或目录独立打包成单独的压缩文件（而非整个目录打包成一个），所有压缩包放入一个以 源目录名_年月日_时分秒 命名的独立目录中，日志文件也生成在该目录内部。备份根目录下按时间顺序保留最近 7 份历史备份目录，超出自动清理最早目录。

功能特点

独立打包：每个源文件/目录单独压缩成 xxx.zip 或 xxx.tar.gz，便于按需恢复单个项目
时间戳目录：备份目录以 源目录名_YYYYMMDD_HHMMSS 命名，每次备份生成独立目录，不覆盖
自动清理：固定保留最近 7 份历史备份目录，超出自动删除最早目录
日志同目录：日志文件 源目录名_YYYYMMDD_HHMMSS.log 生成在本次备份目录内部，和压缩包同级
支持交互式和传参两种部署模式（可指定工作目录和备份根目录）
支持 tar.gz / zip 两种压缩格式
自动过滤已压缩文件，仅显示可备份项
水平多列显示文件列表，支持序号选择或手动输入名称
彩色输出，操作状态清晰可见
跨平台包管理器自动安装依赖（opkg/dnf/yum/apt/apk/pacman/zypper/pkg）

历史备份自动清理（固定保留 7 个，不可改、无需传参）

每次备份先执行清理：扫描备份根目录下所有 xxx_年月日_时分秒 格式文件夹
目录数 > 7 个 → 删除最早生成的目录，再新建本次备份目录

实例使用方法

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

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

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

注意事项

固定保留数量写死在函数 clean_old_backup 内 keep_max=7，如需修改数量只改这里数字即可
日志文件名自动放在本次时间戳目录内部，和压缩包同级
单个文件/文件夹逐个单独压缩成 xxx.zip，不再打包整目录大包
每次备份先清理旧目录再创建新目录，确保保留的是最新的 7 份
备份根目录下的非标准格式目录不会被清理（仅匹配 xxx_年月日_时分秒 格式）
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
确保备份根目录所在磁盘有足够空间
