提问by Kevin
How can I skip backing up my "Downloads" folder?
如何跳过备份我的“下载”文件夹？
here's my code:
这是我的代码：
#!/bin/bash
# Daily backup script
# Create some needed variable
day=$(date +%F)
Folder="/home/ME/"
File="/media/MediaTwo/Copy/UbuntuBackup/$day.tar.gz"
# Backup Server Configuration

# Remove backup files older than 90 days
find $File* -mtime +90 -exec rm {} \;

tar cpzf $File --exclude=Downloads $Folder

The easiest way to exclude your Downloads folder is to add an option (i.e. --exclude) to the tarcommand.
排除下载文件夹的最简单方法是向命令添加一个选项（即--exclude）tar。
I would suggest modifying line 12 of your code to read:
我建议将代码的第 12 行修改为：
tar cpzf $File --exclude "${Folder}Downloads" $Folder
tar cpzf $File --exclude "${Folder}Downloads" $Folder
I think this should do what you're looking for.
我认为这应该可以满足您的要求。

Use extended pattern matching:
使用扩展模式匹配：
shopt -s extglob; shopt -s dotglob
tar cpzf "$File" "$Folder"/!(Downloads)

I sugest this one for maximum speed on multi core machines :
我建议在多核机器上获得最大速度：
tar -c --use-compress-program=pigz -f $File --exclude=Downloads $Folder
