56634: Acronis True Image: how to clone a disk

Using Acronis True Image you can clone basic disks, both MBR and GPT.

Acronis True Image does not allow to clone a single partition; only cloning of an entire disk is possible.

If you are planning to clone a disk from your laptop, please see Cloning Laptop Hard Disk.
Recent versions of Acronis True Image can perform active cloning under Windows/macOS. See the following articles for more information:

.

Source and target disks must have equal logical sector size. Cloning to a disk with different logical sector size is not supported. E.g., you can clone a 512 bytes/sector disk to 512 bytes/sector disk; you can clone a 4096 bytes/sector disk to 4096 bytes/sector disk; but you cannot clone a disk with logical sector size 512 bytes to disk with logical sector size 4096 bytes.

Only basic disks can be cloned with Acronis True Image. You cannot clone dynamic disks.

Source disk volumes can be cloned to the target disk "as is" or resized proportionally. It is possible to clone a larger disk to a smaller one, provided that the smaller hard disk has enough capacity to fit the contents of the larger disk.

If you clone a disk with Windows to external USB hard drive, you will not be able to boot from it. Windows does not support booting from external USB hard drives. Please clone to internal SATA SSD or HDD instead.

It is recommended not to format the source hard disk after the cloning until you are sure that the cloned target disk boots fine.

Cloning RAID disks

Cloning is supported only for simple disk partitioning systems, such as MBR and GPT. Acronis True Image cannot clone RAIDs set up as LVM or LDM. Hardware RAIDs and storage spaces can be cloned provided the environment where Acronis product is running (e.g. operating system) supports them, as Acronis True Image gets the information about RAID configuration from the environment. Cloning of a hardware RAID will work if a reboot is not required: after reboot, the operation continues in standalone version of Acronis True Image, where support of all hardware RAID configurations is not guaranteed and thus the cloning operation may fail after reboot. Acronis development team is working on improving hardware RAID support in bootable environment. If you encounter a case where a hardware RAID cloning requires a reboot and the operation cannot continue because RAID is not recognized in bootable environment, please contact Acronis Customer Central.

Step-by-step guide

If you are going to do system disk cloning, we recommend that you do it using Acronis Bootable Media. 

Even when you start cloning in Windows, the computer will reboot into the Linux environment the same as when booting from the rescue media. Because of this, it is better to clone using rescue media. For example, there may be a case when your hard disk drives are detected in Windows and not detected in Linux. If this is the case, the cloning operation will fail after reboot. When booting from the rescue media, you can make sure that Acronis True Image detects both the source and target disks before starting the cloning operation.
