Linux 定时自动备份数据到 OneDrive/Google Drive

鉴于上次的服务器崩溃事件，写一个数据自动备份脚本就显得尤为重要。折腾了一晚，最终实现效果是每晚三点自动备份数据库和网站等数据并使用 Openssl 加密归档，保留最近一个月的数据，通过开源的 rclone 工具同步到 Google Drive 和 Onedrive 上，这样就万无一失了🍟

1. Shell 脚本

脚本是自己使用，因此比较简单。

#!/bin/bash
# Writen by Atp on Nov 15, 2020
# Website:  https://atpx.com

DATE=`date +%Y%m%d`
BACKUP_TEMP_PATH=/backup/tmp
# Database
DB_NAME=
DB_USR=
DB_PW=
DB_OUT_NAME="db_$DATE"
# Website
WEB_PATH=
WEB_OUT_NAME="web_$DATE"
# Archive
ARCHIVE_PATH=/backup/archives
ARCHIVE_LOG_FILE=/backup/log/backup.log

# Backup mysql
# mysqldump -u$DB_USR -p$DB_PW --databases $DB_NAME > $BACKUP_TEMP_PATH/$DB_OUT_NAME.sql
mysqldump --login-path=$DB_USR --databases $DB_NAME > $BACKUP_TEMP_PATH/$DB_OUT_NAME.sql

# Backup webdsite
cd $WEB_PATH
zip -rq $BACKUP_TEMP_PATH/$WEB_OUT_NAME.zip *

# Archive files
cd $BACKUP_TEMP_PATH
# tar cf - * | openssl enc -e -aes-128-cbc -pbkdf2 -k [password] -out $ARCHIVE_PATH/$DATE.tar.aes
tar cf - * | gpg -e -r [recipient] -o $ARCHIVE_PATH/$DATE.tar.gpg

# Backup the latest 30 days
rm $BACKUP_TEMP_PATH/*
find $ARCHIVE_PATH -name "*.tar.gpg" -type f -mtime +30 -exec rm {} \;

# Sync to Google Drive
rclone sync $ARCHIVE_PATH gdrive:[sync path]

# Sync to Microsoft OneDrive
rclone sync $ARCHIVE_PATH onedrive:[sync path]

# Output log file
echo -e "\e[1;32m---------------------------------------------\e[0m" >> $ARCHIVE_LOG_FILE
echo -e "Backup date: "$(date +%Y-%m-%d)"\t""Finish time: "$(date +%H:%M:%S) >> $ARCHIVE_LOG_FILE
echo -e "\e[1;32m---------------------------------------------\e[0m\n" >> $ARCHIVE_LOG_FILE

这里说明一下，使用mysqldump备份的时候，如果通过账号密码导出会提示使用明文密码不安全的警告，虽然不影响使用，但看着就不爽，因此改用了 MySQL5.7 之后提供的新方式，通过 --login-path= 的方式登录数据库，首先保存一个加密验证信息：

mysql_config_editor set --login-path=[name] --host=localhost --user=[usr] --password

查看所设置的信息：

mysql_config_editor print --all

删除指定信息：

mysql_config_editor remove --login-path=[usr]

值得一提的，我第一次设置的时候毫无疑问的失败了- -，一直无法登录，后来才知道所设置的用户密码中不能包括"#“符号，不然就会报错。

2. 配置 rclone

官方有一键安装脚本，适用于 Linux/macOS/BSD 系统：

curl https://rclone.org/install.sh | sudo bash

之后需要在服务器上配置 Google Dirve 和 OneDrive 的连接，输入 rclone config 命令，根据提示的信息进行操作，下面演示的版本为 v1.57.0，不同版本可能会略有出入，但思路是一样的。

Google Drive

- using defaults
No remotes found - make a new one
n) New remote
s) Set configuration password
q) Quit config
n/s/q> n  # 输入 n，新建远程连接
name> gdrive  # 输入自定义名称，用于区分不同连接

连接 OneDrive 的 token 需要在本地 Windows 电脑上下载 Windows 版 rclone 获取，下载后解压，在 rclone 文件夹中的资源管理器地址栏输入 cmd，打开命令提示符，输入 rclone 配置中提示的命令：

rclone authorize "onedrive"

接下来会弹出浏览器，登录账号进行授权，然后返回 cmd 窗口会出现类似信息：

测试配置

配置完成后，你可以同步一个简单的文件进行测试，比如在 /home/rclone-test 目录下新建一个 1.txt 文件，然后使用同步命令：

rclone sync /home/rclone-test onedrive:rclone-test/temp

然后登录你的 OneDrive 查看 rclone-test/temp 目录下是否有 1.txt 文件。

至于 rclone 完整的命令操作，可以查看官方文档。

3. 定时任务

设置好 rclone 之后就该定时执行备份脚本了，这里通过 Crontab 设置定时任务，每晚两点执行备份脚本，记得给脚本可执行权限：

crontab -e
00 2 * * * /backup/backup.sh

使用说明：

分　时　日　月　周　执行命令
第 1 列：分钟 0-59，每分钟用 * 或者 */1 表示，整点分钟数为 00 或 0
第 2 列：小时 0-23（0 表示 0 点）
第 3 列：日 1-31
第 4 列：月 1-12
第 5 列：星期 0-6（0 表示星期天）
第 6 列：运行的命令

经研究发现，Openssl 并不适合用于文档加密，因此改用 GnuPG
