Disk cloning vs. disk imaging

In both instances, Acronis True Image makes replicating a disk easier and more reliable than ever.

  • Disk Cloning
    • Create an exact, bit-by-bit replica of a disk on a second hard drive
    • Recommended for data migration
    • Instantly boot from a clone by connecting the new drive
    • Requires the same disk space as the original
    • Only one clone can be stored per disk
    • Disk clones cannot be updated with new data
  • Disk Imaging
    • Back up all the contents of a hard drive to a single compressed file
    • Recommended for data recovery
    • Image needs to be restored (installed) before booting
    • Compressed image files are smaller than the original
    • Multiple images can be stored per disk
    • Disk images can be updated incrementally

Flexible data migration

There’s no need to shut down and restart using bootable media. Unlike other disk cloning software, with Acronis True Image you can create a clone directly on your local or external USB drive while still using your Mac or Windows computer.

So keep working, listening to music, or whatever. You’ll be able to boot your entire system directly from the new disk, no problem.


Create a full image backup in two clicks

Make sure you protect everything you need to restore your system, including boot information, applications, settings and hidden files. By creating a full image backup – also called a mirror image backup – you’ll have any recent changes to your files, programs and preferences that have been added since the hard disk was set up … and the incremental approach requires less time than duplicating the entire source drive. You can also automatically replicate your full image backup in the cloud to ensure you always have an off-site copy.

With our disk imaging software, you’ll have an easy, efficient, secure way to restore your system.

Frequently asked questions
Does a system image back up everything on your computer?

Yes, a full image backup – also known as a mirror backup – is an exact replica of everything on your computer's hard drive. This includes your files, the operating system, boot information, apps, and hidden files, as well as the preferences and setting changes you’ve made. Instead of simply copying individual files you might want to protect, a full image backup includes everything you need to restore your system.

How long does it take to create a system image backup?

While the amount of data can affect the speed of creating a mirror image, by using an external drive and Acronis True Image, you can usually create an initial disk image in under 90 minutes. After that updates to that image can be made in a matter of minutes. Imaging software like Acronis True Image lets you schedule frequent full image backups, which ensures any new data or changes to your system are captured on a regular basis.

How to make system image backup?

With Acronis True Image, creating a full image backup is a two-click process. After launching Acronis True Image, select Create a backup. Your entire computer system will be the Backup source by default, so all you need to do is assign the Backup destination, including local storage (internal drive, external hard drive, network drives and NAS devices) or secure cloud storage. Once the destination is set, simply click Start backup.

Is Acronis True Image mirror imaging software?

Yes, but it also enables you to do so much more than traditional imaging software. Not only can you create a full mirror image of your disk, Acronis True Image allows you to back up individual files, folders and partitions, clone a system disk while it is in use (no rebooting needed), and you can archive files to the cloud to open space on your hard drive. It will also back up your Microsoft 365 data, as well as an unlimited number of mobile devices.
