此文件夹在timeMachine 开启时回自动记录备份操作

将导致Mac pro 的存储空间慢慢减少 

解决方案如下

1、手动关掉time machine的移动时的备份功能

2、打开终端，这个命令

$ sudo tmutil disablelocal

3、重启机器，查看存储空间，就会发现备份显示的是0kb

How To disable Time Machine’s MobileBackup

July 24, 2011, Christian Kildau, 4 Comments

Starting with Lion I noticed that Time Machine is running even when my Time Capsule is not available. I also noticed that Finder shows a different amount of used disk space thandf. My MacBook Pro’s SSD also got somewhat slow. Turned out it’s Time Machines MobileBackup function.

 

If you want to disable MobileBackup and free up the abused disk space, simply run the following command and reboot.

 

1	sudo tmutil disablelocal
