How To Create Mirrored Volume in Windows 10

In an Enterprise environment, hard drive failure can affect multiple users simultaneously trying to access their files on the drive and this can be a big blow to all operations that should run without interruption in an organization. With time, all ages and the same thing apply to that hard drive too. Sooner or later, hardware is worn out and your data is lost.




Backing up data on the hard drive or having a safe way to access it, if and when everything goes south is very important, given the importance of data. In this post, we will talk about Hard Drive Mirroring - real-time data replication from original disk volumes to separate secondary volumes, which is a very popular backup solution, and learn how to create Mirrored Volume for Instant Hard Drive Backups on Windows 10.

Make Mirrored Volume for Instant Hard Drive Backup


Hard drives are more vulnerable to failure than other computer components. Drive Mirroring is a technique used to overcome hard drive failure by automatically making multiple copies of data stored on the drive in question.

This way you always have the data you want - even in the case of an unfavorable drive failure. Hard Drive Mirroring is on a RAID-1 level on a standard RAID level (Redundant Array of Independent Disks), where copies of the right and reliable data are stored on two or more disks. After mirroring is active, files between these drives are automatically saved in synchronization so you always have a replica of your real-time data.

Create Mirrored Volume on Windows 10


To continue by creating a mirrored drive, you obviously need two different physical drives. The targeted mirror drive must have the same size or greater than the original drive and it must represent unallocated disk space. If it consists of any data, you can right-click and choose Delete Volume - assuming that you have an open Disk Management tool - to delete the existing data and mark it as unallocated. Once you are ready for the prerequisites, follow the steps below to make mirrored volumes:

  1. Press Windows Key + R on your keyboard to launch the Run tool. Enter diskmgmt.msc here and press Enter. This will open the Disk Management tool.
  2. In the Disk Management tool window, right-click on the disk that is not filled with blanks and select New Mirrored Volume.
  3. In the next window, select the disk from the one available and add it to the right. Select the amount of space you want to dedicate to mirrored volume and click Next.
  4. You can set your chosen drive letter in the next window or leave it, with the default settings. When finished here, click Next.
  5. Next, you will be asked if you want to format the disk before use. Select Format this volume with the following settings and select System file as NTFS, the size of the Allocation unit as Default and set the volume label of your choice for the disk. Also, check the Perform a quick format option. Click Next and complete the process.

If your drive is set to Basic Disk, you must convert it to Dynamic Disk before adding it as mirrored drive, otherwise the option to set it as mirror out.

Note :

  • Random disk read operations on mirrored volumes are more efficient than single volumes. Recovery from disk failure is very fast.
  • Disk write operations are less efficient and Mirrored volumes are the least efficient in terms of space utilization.

Mirroring is often confused as a backup strategy. Let me clarify - no! The main principle behind the existence of mirroring is different from the backup. While the backup focuses on complete data protection and accessibility reliability in the event of drive disruption, mirroring is a matter of keeping your system operating in full time with real-time data replication that is useful in case of a drive failure.

So, you know, when and if the original hard drive failed to read, the system automatically retrieves data from mirrored drive and you don't have to waste your time. Mirroring helps restore data faster while affecting the least system performance.
