Case: how do I clone dynamic volumes?

"I have some volumes on dynamic disks and want to copy some of them to my spare Seagate hard drive for backup. However, it turns out I cannot perform a cloning or copying of dynamic volumes in Disk Management. Is there any easy way to copy dynamic volume to basic disk without data loss?"

Generally, people would like to copy dynamic volumes for extending storage space, upgrading hard disk or backing up important data. But if you’ve ever tried it, you must know the volumes on dynamic disks cannot be easily copied or cloned as on basic disks. What makes the difference? Is there a way to copy dynamic volumes without data loss?

Copy Dynamic Volume

Overview for dynamic volume, dynamic disk and basic disk

To find an effective solution to copy dynamic volumes of dynamic disks, you may need some more information.

What is a dynamic volume?

All volumes on dynamic disks are known as dynamic volumes. Common dynamic volumes include simple volume, mirrored volume, striped volume, spanned volume and RAID-5 volume.

What’s the difference between dynamic disk and basic disk?

A basic disk uses normal partition tables or logical drives to manage all partitions and data. It contains up to 4 primary partitions, or 3 primary partitions and 1 extended partition with multiple logical drives. There are 2 styles of partitions - MBR and GPT. In basic disk, already created partition cannot be changed or modified.

A dynamic uses dynamic volumes to manage data. It doesn't use a partition table to keep track of all partitions, and the volumes can be extended with dynamic disk configuration. In dynamic disk, the number of primary and secondary-extended partitions are not limited.

Can I convert dynamic disk to basic disk for volumes copying?

A basic disk can be easily converted to a dynamic disk without losing data. In Disk Management, right-click the basic disk, you will find the option Covert to Dynamic Disk. Just choose it and follow the wizard to complete the conversion.

However, only empty dynamic disk can be converted to basic disk, and the conversion is irreversible. That is to say, if you want to convert dynamic to basic, you need to delete all the existing volumes, which is obviously not a good way to copy dynamic volumes unless you make a backup first.

Convert To Dynamic

How to copy dynamic volumes on dynamic disks easily?

As mentioned above, you cannot directly copy a dynamic volume, and the conversion from dynamic to basic requires you to delete all the volumes in dynamic disk. In this case, a powerful dynamic disk clone software is indispensable.

It should be able to directly copy dynamic volumes including data volumes and system volumes to another disk, thus you can achieve replacing or upgrading hard drive without losing data. And the operation better be as simple as in Disk Management.

To meet all these standards, AOMEI Backupper Professional is a reliable choice.

★ It works on all Windows PCs and enables you to simply copy volumes between MBR and GPT, dynamic disk and basic disk. Individual files and folders are also supported.

★ In addition to cloning dynamic disk, it allows you to back up all the data to an image file, which cannot be accessed directly but will definitely save the storage space.

★ For cloning, there are options to edit partition size, choose intelligent or sector-by-sector mode, improve the performance if the destination is an SSD, etc. As for backup, you can set up a schedule to run it automatically, choose between full/incremental/differential backup, compress/split/encrypt the backup image, create a rule to auto delete old backups, etc.

Here are 2 common ways to copy dynamic volumes with AOMEI Backupper:

1. Clone dynamic volumes to basic disk

If you want to create an exact copy of dynamic volumes to a basic disk, partition cloning is the easiest solution. It’s safer than manual copy & paste, and the cloned data can be accessed directly and normally.

With AOMEI Backupper Professional, the operation can be so easy. You don’t need to covert the dynamic disk to a basic disk at first, just follow these steps:

◆ If you want to clone dynamic volumes to another hard drive, connect it to your computer. If there’s only one drive bay, use an USB-to-SATA adapter to help.
◆ Download and install AOMEI Backupper Professional.

Step 1. Launch the software, go to Clone tab and select Partition Clone to copy a volume.

If you want to copy only system volumes to another disk, System Clone would be a better choice. With it, you can migrate OS from HDD to SSD, from SSD to another SSD, etc.

Partition Clone

Step 2. Select the volumes on dynamic disk that you want to clone, then click Next.

Select Dynamic Data Volume

Step 3. Choose the destination to save the dynamic volumes. In this case it should be on the basic disk you just connected. Click Next to continue.

The destination can be an unallocated space or an existing partition. But please note all the data in the destination will be overwritten, so if there’s any important data, please backup it at first.

Dynamic Data Volume Destination

Step 4. Confirm the operation and click Start Clone. Before that, you can also click Edit Partition, SSD Alignment or Sector By Sector Clone to optimize the cloning as you like.

Edit Partition - modify partition size and drive letter on the destination disk.
SSD Alignment - accelerate the reading and writing speed if your destination disk is an SSD.
Sector By Sector Clone - create an intact copy of all the sectors with a longer cloning time. Without ticking it, the software will run intelligent cloning by default, which only copies used sectors and therefore save your storage space.

Clone Dynamic Data Volume

Tips: you cannot clone an entire dynamic disk directly, but with System Clone and Partition Clone, you can clone dynamic system volumes plus other data volumes separately to achieve the same goal of cloning dynamic disk.

2. Copy dynamic volumes as a backup image

The purpose of copying a dynamic volume is not limited to replace hard drive without losing data or such like. If all you want is to copy these volumes as a protection over important data, it’s also a feasible way to backup them to an image file, which will doubtlessly save your storage space.

Step 1. Launch AOMEI Backupper, go to Backup tab and choose Partition Backup. If you want to copy only system partitions, choose System Backup instead.

Choose Partition Backup

Step 2. Click Add Partition or Volume to add the dynamic volumes you want to copy, then click Add. You can copy multiple volumes at the same time.

Add Dynamic Volume

Step 3. Choose a destination to store the image file. In addition to internal/external hard drive, you can also choose USB, cloud drive, NAS, etc. as long as there’s sufficient space. Click Start Backup to execute the task.

Options - compress, split, encrypt backup image, choose backup mode, write comment, etc.
Schedule - set up a schedule to automatic execute the backup. Options include Daily/Weekly/Monthly/Event triggers/USB plug in.
Scheme - set up a rule to delete old backups automatically so as to free up your storage space.

Start Backup


Usually you can copy partition in Disk Management with a simple click, but to copy dynamic volumes, a powerful clone tool supporting dynamic disks is required.

AOMEI Backupper is such a program allowing you to backup or clone files, partitions, operating system and the disk. It comes with great compatibility and complete features, which can not only be used for data migration, but also for daily data protection. Even if you want to backup or copy dynamic volumes in Windows Server, there’s also a Server edition for you to choose.
