About Windows Server 2019

Windows Server 2019, a part of the Windows NT family of operating systems, is the latest version of the Server operating system by Microsoft. It is built on the strong foundation of Server 2016 but with more features than Server 2016.

Gratifyingly, Server 2019 has made numerous innovations on four key themes: Hybrid Cloud, Security, Application Platform and Hyper-Converged Infrastructure (HCI). This is why more and more organizations or companies are willing to upgrade to Windows Server 2019.

Why need to clone C drive in Server 2019?

As you know, C drive (C:) is the main hard drive partition that contains the operating system, related system files, user profile, and other applications, etc. As the number of Server 2019 users’ increases, the need to clone C drive in Server 2019 is also increasing. Generally speaking, 3 aspects are responsible for this action.

  • Clone C drive to a new computer. The most common situation is that you bought a new computer, but reinstalling Server 2019 on the new computer is a troublesome job. C drive clone can save you from system reinstallation.

  • Clone C drive to external hard drive for a larger capacity. It is very common that C drive or the disk which contains C drive is filled up. At this time, you have to transfer data from C drive to a new larger drive.

  • Clone C drive to another drive for a much better performance. Using SSD for OS and HDD for storage is the best arrangement for hard drives. Compared to hard disk drive, solid-state drive has more merits like lighter volume, faster speed, and lower consumption, etc. Thus, many users would rather clone C drive to SSD in Server 2019.

To make this task as easy as possible, a professional and reliable utility has been developed – AOMEI Backupper Server. Following are its main features in regard to clone:

  • Disk Clone: it allows you to clone an entire disk to another disk, such as clone HDD to SSD or clone SSD to larger SSD.

  • Partition Clone: it enables you to copy a particular partition on a disk to another partition. It supports NTFS, FAT32, and exFAT partition, etc.

  • System Clone: it can help you migrate OS to SSD or another HDD easily by cloning only system related partitions.

  • Intelligent clone: it will clone only the used part of the source disk/partition by default, which makes it possible to clone C drive to a smaller drive.

  • OS supported: Windows Server 2003/2008/2011/2012/2016/2019 (including R2), SBS 2003/2008/2011, Windows 10/8.1/8/7/XP/Vista

How to clone C drive to SSD in Windows Server 2019 efficiently?

To clone C drive in Server 2019, it is suggested to use System Clone rather than Partition Clone. System Clone will choose C drive and boot related partitions like System Reserved Partition automatically as the source partitions, thus ensuring you can boot OS from the cloned drive successfully later. Let's see how it works.

Before cloning, connect the new SSD to your computer and make sure it can be detected by Server 2019. Please note that all data on the new SSD will be overwritten after cloning. You’d better do a disk backup of the new SSD if there are important data.

Step 1. Install and open this Windows Server clone software. Select System Clone under Clone tab.

Step 4. Now, you can change boot order in BIOS or replace old hard drive with the new SSD to boot from the cloned drive. The second method is recommended.


  • If you tick Sector by sector clone in Step 3, the program will clone all sectors on the source partitions whether they are used or not. It requires the destination drive to be equal to or larger than the source drives.

  • The original C drive will not be wiped out. You can use it as a backup or a secondary storage.


From the above you can see that all the steps are very easy to learn, even for a beginner. By the way, the cloning process will not interrupt the operations that are running, so you can do your work while cloning.
