3. Click Next. When prompted about exporting the private key, select Yes to include the private key.
4. Click Next, then check the Password box, set a password to protect the backup, and click Next.
5. Choose where you want to save the backup file and click Finish to complete the export process.
Method 3: Backup Encrypting File System with Command Prompt
