Mac Security and Data Recovery How-to Guide (Backup and Recovery)

Data is a precious asset and should be treated accordingly. Most Mac users take the intactness of their personal files for granted and don't bother safeguarding them proactively until disaster strikes. However, this is a slippery slope. Human error, hardware failures, and malware activity can ruin your data when you least expect it.

We all slip up sometimes and delete files unintentionally. Storage devices are susceptible to physical impact, aging, and corruption. Malicious code such as Mac ransomware can badly damage your files and make them inaccessible.

You should have a plan B for such predicaments. This guide will shed light on Mac security and Mac data recovery best practices. You will learn how to protect your files against unwanted interference and how to recover them if they suddenly go missing.

Part 1. Mac Data Security Fundamentals

An effective backup strategy is the best way to mitigate risks to your data no matter where they may come from. Recovering from a ransomware attack or dealing with the aftermath of disk corruption is easy as long as you have extra copies of your files stored in a safe place. Data encryption is another layer of protection that will make hackers frown even if they gain unauthorized access to your device.

Thankfully, your Mac provides both backup and encryption features out of the box. Here is a summary of effective techniques to strengthen your data security and privacy on Mac.

Method 1. Back up Your Data Using Time Machine

You don't have to reinvent the wheel – macOS comes with a backup feature that will do all the tedious work for you. Keep in mind that you need to connect an external storage device to your Mac to maintain data backups this way.

Step 1: Go to System Preferences

Click the "System Preferences" icon in your Dock. This will open a screen that embraces all controls and customizations that allow you to personalize your Mac experience.

Step 2: Set up a Data Backup with Time Machine

Open "Time Machine" from the System Preferences pane. Click "Select Backup Disk," pick the external media for backups, and follow further prompts to complete the process. From now on, Time Machine will be making periodic backups automatically.

Be advised that the first backup can take a long time to complete (most likely several hours), depending on the amount of data on your Mac. Once the feature is configured, you can restore previous versions of your files whenever you want. Once your files are lost, you can easily recover deleted files from Mac at anytime.

Method 2. Back up Your Data to the Cloud

You can alternatively use cloud services such as Dropbox, Google Drive, or iCloud to store backup copies of your files. The key benefit of doing so is that you can access your files anywhere from any device.

Method 3. Use FileVault to Add Encryption and Extra User Verification to the Mix

FileVault automatically encrypts files on your startup disk, thus making it useless for potential intruders who may stealthily gain a foothold on your Mac. When it's enabled, you will also be required to log in with your admin credentials every time your machine starts up.

Step 1: Open the FileVault Feature

Click the "System Preferences" icon in the Dock, select "Security & Privacy," and click the "FileVault" tab.

Step 2: Enable FileVault

Before you activate this feature, click the padlock sign at the bottom of the screen and enter your admin password to make changes. Then, click the "Turn On FileVault" button and follow on-screen tips to have your data secured through automatic encryption.

Part 2. How to Recover Data on Mac

Data loss scenarios vary, and so do the applicable recovery mechanisms. If you have accidentally deleted a file and it's still in your Trash, reinstating it is very easy. In case data has become corrupted or damaged in some other way, the procedure is more challenging. Either way, there are tried-and-tested methods to address the issue for Mac OS security.

Method 1. Recover Deleted Files from Trash

If the files you need to recover are still in the Trash folder, this technique is definitely worth a shot. It is something like the Mac system recovery. Here is how you do it.

Step 1: Open the Trash folder

Click the Trash icon in your Dock as illustrated below.

Step 2: Restore Files You Need Back

Check the Trash folder for the item or items you want to restore. For your convenience files are grouped by the time they were deleted (Today, Yesterday, Previous 7 Days, Previous 30 Days, etc.). Right-click the file you need and select "Put Back" in the context menu. It will now reappear in the directory it was originally removed from.

Method 2. Recover Data from Time Machine Backup

If you have previously enabled automatic Time Machine backups, using this feature is an amazingly simple way to get your missing files back. It works wonders even if you have emptied your Trash and the required files are no longer there.

Step 1: Open Time Machine

Click the Time Machine icon in the Finder toolbar and select "Enter Time Machine."

Step 2: Restore the Latest Versions of Your Files

Select the item you want to reinstate. The feature displays a timeline so that you can pick the most recent version or an older one if you so desire. When done, click the "Restore" button. That's it. The file is back. Redo the procedure for all the other items you want to recover.

Method 3: Use Coolmuster Data Recovery for Mac
