把一些重要的配置文件定时保存在Telegram上，以防服务器出现硬件故障导致文件丢失。
#!/bin/bash
# Backup important files to telegram

BACKUPPASS='XXXXXX'
api_key='bot1577714372:BotKeyHereZtWBcXa0Fj7qHzLY8hTbqfzo'
chat_id='-10013chat_id50'
fList=$(tr '\n' ' ' < /data/_run/telegram-backup-data.backuplist)
fName=/tmp/tgbaklp1tt_$(hostname)_$(date +"%FT%H%M%S").tar.gz
fNameEnc=$fName.enc
tar -czvPf $fName $fList
openssl enc -aes256 -in $fName -out $fNameEnc -pass pass:"${BACKUPPASS}" -md sha1
# decrypt use -

curl -F chat_id=$chat_id -F document=@"${fNameEnc}" https://api.telegram.org/$api_key/sendDocument > /dev/null
rm -rf $fName $fNameEnc
exit 0
上面的脚本配合添加一个备份列表文件/opt/scripts/backuplist，将需要备份的文件/文件夹逐行添加
cat > /data/_run/telegram-baskup-data.backuplist <<EOF /etc/sysctl.conf /etc/sysctl.d /etc/sysconfig/iptables /etc/sysconfig/ip6tables /etc/systemd/system/*.service /etc/ssh/sshd_config $HOME/.vimrc $HOME/.bashrc $HOME/.gitconfig $HOME/.ssh EOF
chmod +x /data/_run/telegram-baskup-data.sh crontab -e # 添加 # run every wed 0110am 10 1 * * 3 /data/_run/telegram-baskup-data.sh
