Data security is an issue of extreme concern to everyone. Who do not want their important data exposed in public places. This article to your Mac-depth analysis of several safe manner.
Data security divided into two categories: 1 from theft; 2 avoid data corruption.
Prevent data theft Section 1: Firmware Password
Most ordinary Mac users will set up a user account password, but you may not know the password only one command can be easily lifted. For the strong hands of people, the password is useless. If you are a very important Mac data lost, only to set up the account password, then the other as long as Baidu, you can see all your data.
Solution: open firmware password, the other party will not be able to reset your user account password.
1, after opening Mac hold down the Command (⌘) -R immediately start the recovery from macOS. Release the button when you see the Apple logo.
2, in the "Utilities" window appears, select the "Utility - Firmware Password Utility" from the menu bar.
3. Click "Open Firmware Password."
4. Enter the firmware password in the fields provided, then click "Set Password." Remember this password.
5, "Utility Firmware Password" exit, and then select the top left corner of the Apple () menu> "Restart."
"Not all models support firmware password." Be sure to keep in mind their own firmware password once you forget your firmware password, you need to provide a receipt to the Apple Store invoice processing application, take several business days. If your invoice receipt has been lost, then congratulations: finally have an excuse to get a new Mac.
Prevent data theft Section 2: FileVault disk encryption
Firmware password and user account passwords are just a lock. Others find a way to pry open the lock or bypass this road, you can still read your data. For example, try to remove the Mac hard disk, read the contents inside by special tools. So if there are highly confidential content. You can use FileVault full disk encryption, as long as your computer at work, it will always encrypt the contents of your disk. Of course, little will consume more power. Even if the hard disk torn down, you can not read the contents inside.
Activation:
1、系统偏好设置 - 安全性与隐私
2、点击 FileVault 标签页
3、连接电源情况下， 打开 FileVault
注意事项：牢记恢复秘钥，或者你的 Apple ID 帐号密码。一旦全部忘记，你的资料就真的化为乌有，别去找苹果，他们也无能为力。
避免数据损坏第 1 节：Time Machine
工作中，数据损坏丢失的概率远比硬件被盗的概率大，且大很多。
数据的价值比硬件本身要贵，且贵很多。
Time Machine 会将你的所有文件备份至外置储存设备，以便你可以稍后进行恢复或查看过去某个时刻的状态。
如果你曾经发生过丢失重要资料的经历，并且讨厌传统复制粘贴方式的备份。那么请继续往下看。
Time Machine 备份优点：
1、后台自动备份，对工作没有任何打扰；
2、备份所有内容，甚至包括电脑里的垃圾文件；
3、迅捷恢复到之前备份过的某一天的某时刻。
如何操作：
1、买一个大于等于电脑硬盘容量的移动硬盘，任何牌子。笔者在电商某东买的某芝 1TB 移动硬盘，无故障运行好几年；
2、定期把硬盘连接到电脑上。后台会自动备份；
3、初次启动时，需要「系统偏好设置 - Time Machine - 自动备份」打开，选中在菜单栏中显示 Time Machine；
4、一定要开启硬盘加密。一块没有密码保护的备份硬盘反而会成为安全漏洞。
根据资料重要程度，来决定硬盘连接电脑的频率。比如我差不多一个月连接一次，也可以每周一次或者买 Time Capsule 来实现备份，只是成本有些高。 如果某一天要还原备份，那么点击屏幕右上角的 Time Machine 图标即可。
避免数据损坏第 2 节：网盘
在 Mac 系统下好用的备份网盘有以下几个。
国内首推：坚果云。速度超快，增量备份，跨平台支持，简直是一个完美的工具。免费空间不是很大，但是只备份文档之类的重要文件是足够。更多需求，就付费吧。
iCloud Drive：现在苹果的云储存服务器已经部分在中国，访问速度和以前相比快了很多。笔者 20M 的宽带，下载速度经常达到 2MB/s，但是其区分备份成功和未备份标识不够清晰，不如 Dropbox 看着明朗。如果你的工作生态圈都是 iOS 和 Mac，那不妨试试，价格也不贵。如果你是跨平台用户，坚果云更好，支持两步验证，可以用 WebDav，差异性备份等等，中国区最好用的，没有之一……
国外：Dropbox 和 Google 备份和同步。目前笔者更喜欢用 Google 备份和同步服务。功能和免费空间比 Dropbox 大很多。国内用户如果没有特殊需求，文档交流也都是中国同事的话，还是推荐用坚果云。安全，稳定，有保障。虽然大家对国产网盘的安全性都表示怀疑。
设备有价，数据无价。别总是等到资料泄露，丢失时才想起来，为啥当初没有仔细看文章呢。
