There are many reasons why you need to copy hard disk drive, for example, the entire hard disk is full, so you need to clone and migrate to larger one. If you installed Operating System in a traditional HDD, you may want to copy HDD to SSD to migrate OS, because SSD is much faster than mechanical hard disk. In this article, I'll show you detailed steps how to clone entire disk and single partition to another one on Windows Server 2019.
There are 2 ways to copy disk partition on Windows Server 2019: sector-to-sector and file-to-file copy.
It is very very slow to run sector to sector copy, because all sectors in source and target disk must be exactly the same. In this way, you cannot change partition size. If you copy a 250GB disk to a 500GB disk, the first 250GB will be the same with the source disk, the remaining 250GB will be Unallocated.
It is much faster to run file-to-file copy, because it works on file system level. It ensures all files are copied to new disk, but the sectors may be different. However, you won't find any difference in daily usage. Another benefit is that you can change size of the partitions on target disk.
In most cases, there's no need to waste a long time to do sector to sector clone.
Follow the steps in the video to clone Server 2019 hard disk:
When copying partition volume to a disk on Windows Server 2019, there must be Unallocated space in the target disk. If there's no such space, you can shrink a large partition to generate. This Unallocated space should be equal or larger than the used space of the partition that yo want to copy from.
To shrink a partition, right click it in NIUBI Partition Editor and select "Resize/Move Volume", drag either border towards the other one in the pop-up window.
Steps to copy partition volume in Windows Server 2019:
In many servers, drive D is used to install programs, so you should change drive letter of target partition to D. To other data volumes, you may ignore the step to change drive letter.
Besides copying disk partition in Windows Server 2019, NIUBI Partition Editor helps do many other operations such as shrink, extend, move, merge, convert, defrag, wipe, hide, scan bad sectors. Better than other tools, it has advanced Virtual Mode, 1-Second Rollback and Cancel-at-well technologies to protect system and data while modify disk partition.
