Backing Up Efs Folder: Everything You Need To Know


If you are an Android user, you might have heard about the EFS (Encrypting File System) folder. This folder contains crucial data related to your device, including IMEI, Wi-Fi MAC Address, and other important information. Losing this data can be a disaster as it can render your device useless. That’s why it is essential to back up the EFS folder regularly. In this article, we’ll guide you on how to back up the EFS folder effectively.

Step 1: Root Your Device

The first and foremost thing you need to do is root your device. If you haven’t rooted your device yet, you can easily do so by following the instructions available online. Rooting your device will give you access to the system files, which are necessary for backing up the EFS folder.

Step 2: Install a Custom Recovery

Once you have rooted your device, the next step is to install a custom recovery. TWRP (Team Win Recovery Project) is the most popular custom recovery available for Android devices. You can download and install it by following the instructions available online for your specific device.

Step 3: Boot Into Recovery Mode

After installing the custom recovery, you need to boot your device into recovery mode. You can do this by turning off your device and pressing the required key combination to enter recovery mode. The key combination varies depending on the device you are using.

Step 4: Backup EFS Folder

Once you are in recovery mode, select the “Backup” option and choose the EFS folder. Make sure to store the backup in a safe location, such as your computer or cloud storage. You can also use a third-party app, such as Titanium Backup, to back up the EFS folder.

Step 5: Verify Backup

After backing up the EFS folder, it is essential to verify the backup to ensure that it is working correctly. You can do this by restoring the backup and checking if the data is intact. If the data is missing or corrupted, you need to redo the backup process.

Step 6: Regularly Back Up EFS Folder

Backing up the EFS folder once is not enough. You need to do it regularly to ensure that you have the latest data in case of any mishap. We recommend backing up the EFS folder weekly or monthly, depending on your usage.


In conclusion, backing up the EFS folder is crucial for every Android user. Losing this data can cause significant problems, and it is essential to take preventive measures to avoid such situations. Following the steps mentioned above, you can easily back up the EFS folder and ensure that your device is safe and secure.
