The Windows 10 has a feature that allows you to configure an external hard drive to record a computer mirror for backup purposes. With the Storage Spaces feature, the user can keep a copy of the data working automatically without relying on a third-party program.

How to Use an External Hard Drive for Backup via Mirroring on the PC

Once configured, the Windows tool writes the old and new files to both disks simultaneously. If one fails, the redundant device retrieves the information. Learn in the tutorial how to configure on PC.

Step 1. Open Windows Search and type “Storage”. Then click on the corresponding menu in the results list;

Step 2. In the storage settings, look for the item “Manage storage spaces”;

Step 3. This is the wizard responsible for creating the mirror of your HD on an external device or on a second disk installed on the computer. To proceed, connect the external hard drive to the computer, if applicable, and click “Create a new pool and storage space”;

Step 4. Select your HD from the list and click on “Create Pool”. Remember that the process will format the external hard drive and erase any recorded content there. If there are important files in memory, make a backup before proceeding;

Step 5. Give a name and a letter to the disk and select the REFS file system. Below, choose “Simple (no resiliency)” to copy files from the HD to the external HD automatically. You can also create a two-way or triple mirror if you have two or three external HDs;

Step 6. Next, you must select the size of the pool. Space can be the same as the external HD or even larger if you are willing to switch external HD when the storage runs out. Finally, click “Create storage space.”

After a formatting process, you will see an extra drive in Windows Explorer indicating the new disk. From there, all the files on your PC will be synchronized with the HD, which can be used to recover data if there is a malfunction in the HD installed on the computer. Source:
