Carbon Copy Cloner, SuperDuper!, ChronoSync, and Acronis True Image for Mac offer cloning-related workflows; Apple Time Machine is a versioned backup alternative, while Get Backup Pro is worth considering only after checking its current capabilities. These tools are not interchangeable, and a clone alone is not a complete recovery plan.
What cloning does—and what it does not
A clone copies data from one drive to another, often to create a local duplicate. A versioned backup retains earlier file states, synchronization keeps selected locations aligned, and migration moves data or settings to another Mac. Some apps span more than one of these jobs, but the distinction matters: a synchronized deletion can also affect the other copy, while a clone may not provide the file history you need to recover an older version.

For a bootable external macOS installation, the cloning app is only one part of the process. Apple Support says an external USB or Thunderbolt storage device can be used as a startup disk after macOS is installed on it. That guidance does not guarantee that every third-party clone will boot in every Mac configuration. Apple silicon also needs a working built-in startup disk to start from external storage, and an external macOS installation is specific to the Mac model. See Apple’s external startup disk guidance.
Six Mac backup and cloning options
| Option | Best fit | Evidence-based strengths | Check before choosing |
|---|---|---|---|
| Carbon Copy Cloner | Customizable scheduled local backup or cloning | Macworld’s 2025 comparison highlights configurable scheduling, scripting, NAS support, and SafetyNet. | Confirm current macOS and Apple silicon behavior, whether the workflow preserves file history, and whether external booting is supported for your setup. Macworld cautions that Apple restrictions can make bootable external volumes difficult. |
| SuperDuper! | Straightforward local cloning | Macworld describes scheduling, scripting, APFS and HFS+ support, and a simple interface in the reviewed version. | Check current network-volume support and which functions require payment. The reviewed version did not support network-volume backup. |
| ChronoSync | Synchronization and flexible backup destinations | Macworld describes customizable backup tasks, scheduled jobs, bootable backup, and network or cloud destinations. | Verify current destination and bootability support. Its broader workflow options can make the interface more complex. |
| Acronis True Image for Mac | Disk cloning through a dedicated utility | The 2026 Mac user guide documents a Clone disk utility and lists external drives and USB flash drives as possible destinations. | Acronis says the destination’s total capacity must be more than 10% greater than the used space on the source. This is an Acronis-specific rule; check the current edition and whether it supports your Mac and intended workflow. See the Acronis True Image for Mac 2026 user guide. |
| Apple Time Machine | Built-in incremental backups and file history | Macworld describes Time Machine as an incremental backup that works with Migration Assistant. | It is a backup alternative, not a one-to-one clone. Check Apple’s current restore workflow and whether its history suits your recovery needs. |
| Get Backup Pro | A possible Mac backup app to investigate | Macworld includes it in its comparison, but the available comparison details do not establish enough features to support a strong recommendation. | Confirm the current product, macOS compatibility, cloning behavior, and price before relying on it. |
The feature descriptions for CCC, SuperDuper!, ChronoSync, Time Machine, and Get Backup Pro reflect Macworld’s 2025 comparison, not a standardized test of all six tools. Product features, compatibility, prices, and licensing can change; check the developer’s current documentation before purchase or setup.

How to choose for your job
For a local duplicate
Start with a clone-focused workflow such as CCC or SuperDuper! if you want a scheduled or one-time local copy. Compare scheduling and scripting needs, and check whether the app’s current version supports the destination and Mac configuration you have. A local duplicate is useful, but it should not be the only copy of important data.
For flexible synchronization or destinations
ChronoSync is the strongest fit among these options when task customization, synchronization, or network and cloud destinations matter more than a minimal cloning interface. Confirm that the destination type and any bootable-backup behavior you need are supported in the current version.

For a disk-cloning utility
Acronis documents a specific Clone disk utility. Check its current edition and capacity rule before starting: the destination must exceed the source’s used data by more than 10%, according to the 2026 Mac guide. Do not apply that threshold to other cloning apps.

Time Machine is the built-in incremental-backup choice in this comparison, and Macworld notes its relationship with Migration Assistant. If your goal is moving to another Mac rather than making a duplicate drive, assess the migration workflow directly instead of assuming a clone is the right tool.

Prepare an external drive
An external SSD can serve as a destination for a Mac backup or startup-disk workflow; Apple recommends APFS especially for an SSD used as a startup disk. Apple accepts Mac OS Extended (Journaled) for traditional hard drives and requires it for macOS Sierra 10.12 or earlier. Choose the format for the intended use and macOS version rather than assuming all drives should be erased or formatted the same way.
- Check that the destination has enough capacity for the data and any history or additional copies the selected app requires.
- Before erasing or repartitioning a drive, confirm that it contains no data you need to keep.
- If you intend to start a Mac from the external installation, follow Apple’s current startup-disk instructions and verify compatibility for that specific Mac.
Apple’s guidance establishes that external startup is possible after installing macOS, not that a third-party clone is guaranteed to boot. On Apple silicon, the built-in startup disk must still work, and the external macOS installation is specific to the Mac model.

Practical decision checklist
- One-time copy: Choose a cloning workflow and verify source, destination, and current Mac compatibility.
- Recurring local backup: Compare scheduling, scripting, and how the app handles prior file versions.
- Network or cloud destination: Check current destination support; Macworld’s reviewed SuperDuper! version did not support network-volume backup, while its ChronoSync comparison describes network and cloud options.
- Bootable external macOS: Treat bootability as a separate compatibility requirement and follow Apple’s startup-disk guidance.
- Restore older files or migrate: Look at versioned backup or migration workflows rather than treating a clone as a complete recovery plan.
- Price and licensing: Verify current terms directly with the developer; the cited comparison does not establish up-to-date prices or trial terms.
