How it works

Bootable backup in three steps

From download to a verified, bootable clone — under 10 minutes on Apple Silicon, no expert knowledge required.

Download & install

Grab the carbon copy cloner download for Mac free from this page and drag CCC into your Applications folder. ~30 MB · Apple-notarised installer.

Pick source & destination

Choose your startup disk as source, plug in an external SSD as destination, and set a schedule. CCC handles APFS, snapshots and verification automatically.

Start the first clone

Click Start. The first run copies everything; every later run only copies what changed. If a drive ever fails, you boot from the clone and keep working.

What CCC does

Everything a serious mac backup needs

Six modules in one app — each one closes a different recovery gap so a single failure never costs you your work.

01

Bootable mac hard disk clone

Create a complete, bootable copy of your Mac's startup disk. Plug in the destination drive, hold Option at boot (or use Startup Disk on Apple Silicon), and you're up and running from the clone in seconds.

03

APFS snapshots

Roll back to any prior state — restore a single file or an entire folder from a week ago.

04

Cloud & network destinations

Back up to local drives, NAS, SMB/AFP/NFS shares or cloud storage — chain destinations in one task for layered protection.

05

Byte verification

Checksum pass after every clone confirms source = destination exactly.

Carbon Copy Cloner: the bootable backup built for dev workstations

Mac carbon copy cloner is the only backup tool that handles a developer's Mac the way a developer actually uses it. CCC clones the signed system volume, preserves the macOS file permissions a dev environment depends on, captures Xcode DerivedData and simulator runtimes, includes Docker images and Homebrew installs, and keeps ssh and gpg keys with their octal permissions intact. The result: a bootable mac hard disk clone that drops onto a new MacBook and your dev environment runs immediately, no brew bundle, no Xcode redownload, no dotfile-restore weekend.

Built by Bombich Software since 2002, carbon copy cloner (ccc) is free for the core bootable-clone capability and is the de-facto cloning software for engineers who refuse to lose a working dev box to a soldered Apple Silicon SSD. This guide explains what is carbon copy cloner from a dev's angle, how it compares to SuperDuper for engineering workloads, the Windows equivalents when you switch laptops mid-project, and the workflow that ships a backup macbook ready to compile on day one.

Quick answer: Is carbon copy cloner free? Yes — the bootable mac hard disk clone, scheduled tasks and snapshot retention are in the free download. Carbon copy cloner mac free covers every dev-workstation backup scenario described below.

What CCC handles

What is Carbon Copy Cloner on a developer's Mac

The "carbon copy" principle for a dev workstation: clone the source disk so completely that booting from the destination drops you into the exact same development environment. Carbon copy cloner for mac executes that principle correctly on Apple Silicon's signed system volume — APFS snapshots, file permissions, extended attributes, sparse files, hard links and resource forks all preserved.

For developers this matters because a Mac dev environment is not a folder of files. It is Xcode + Command Line Tools + Homebrew + dotfiles + ssh keys with chmod 600 + a global node_modules cache + Docker overlay layers + half a dozen language runtimes pinned to specific versions. Reinstalling that stack from scratch is a two-day job. Booting a CCC restore takes 90 seconds. That ratio is why mac carbon copy cloner is on every senior engineer's external SSD.

"My SSD failed during a release. I booted from the CCC clone, finished the build, shipped the binary — same machine state, no rebuild."

Three pillars for engineers

Carbon copy cloner for Mac: what a dev backup must do

Three capabilities matter most when CCC backs up a developer Mac — and they are exactly the ones generic backup software gets wrong on Apple Silicon.

Signed system volume clone

CCC mac handles Apple Silicon's signed system volume correctly — boot directly from the clone with Cmd-R, no rosetta dance, no kernel-extension reauthorisation.

File permissions preserved

ssh keys at chmod 600, sudoers config, Docker socket permissions, /usr/local ownership — every bit preserved on the clone. Boot, run, no chmod weekend.

Scheduled incremental + APFS snapshots

Hourly or daily Smart Updates copy only changed files. APFS snapshots let you roll the destination drive back to last week's environment when an upgrade goes sideways.

CCC vs the rest

Why CCC beats the alternatives for engineers

The three comparisons developers actually run when picking backup software for mac. CCC wins the engineering-workstation case on every axis that matters: signed system volume handling, file-permission fidelity and scheduling depth.

superduper vs carbon copy cloner
CCC handles dev edge cases SuperDuper cannot SuperDuper makes a perfect basic clone. CCC adds Smart Update scheduling, APFS snapshot history, cloud destinations, ssh-permission preservation under macOS Tahoe and proper handling of the dev directories most clone tools choke on.
vs Time Machine
Time Machine recovers files; CCC recovers a working dev box Time Machine restores documents in random order. A CCC clone boots into your exact dev environment — Xcode signed-in, brew up to date, ssh keys still authorised against your git remotes.
vs cloud backup
node_modules on your SSD, not on someone else's server Cloud backup uploads every gigabyte of node_modules and Docker layers monthly — bandwidth waste and a compliance headache for client code. A local mac hard disk clone keeps every byte on hardware you own.
Windows engineers

Carbon copy cloner for PC and Windows dev rigs

The official carbon copy cloner is a Mac-only build — there is no carbon copy cloner windows release, never has been. For Windows engineers who need the same disk-clone-and-restore guarantee, three free tools cover the developer workflow: WSL2 dev images, Visual Studio installs and Docker Desktop volumes all survive a clean restore.

Pair any of the three with an external NVMe SSD and you get the Windows equivalent of a backup macbook workflow — full system clone, bootable on a new chassis, restored in 20 minutes.

How to back up your Mac dev workstation with CCC

Setting up backup for macbook engineering rigs with CCC takes ten minutes the first time. After the initial Smart Update clone, every later run only copies changed source, build artifacts and Docker layers — fast even when DerivedData hits 40 GB.

Carbon copy cloner download

Grab the carbon copy cloner download from the Download button below — ~30 MB, Apple-notarised, universal binary, no subscription. Drag to Applications.

Pick source & an external NVMe SSD

Source: Macintosh HD (your full dev workstation). Destination: external Thunderbolt 3 or USB-C NVMe SSD at least as large as your used space. CCC handles the signed system volume automatically.

Schedule Smart Updates + APFS snapshots

Schedule daily incremental Smart Updates. Enable APFS snapshot retention on the destination so you can roll back to last week's dev environment if a brew upgrade breaks the toolchain.

Test the boot before you need to

Once a quarter, hold Option at boot and boot from the clone. Run a quick build to confirm — if the binary compiles, the back up your mac plan works.

CCC schedule editor — hourly, daily, event-driven dev backups

Schedule once, forget it. Daily Smart Updates run while you sleep — only changed source, builds, Docker layers and dotfiles get copied.

Why engineers back up

Why every dev workstation needs a bootable mac hard disk clone

Apple Silicon storage is soldered. A logic-board failure is a permanently lost SSD — no third-party recovery service can pull the data. iCloud syncs documents, not dev environments. Time Machine restores files in random order, not a working compiler stack. A current bootable carboncopycloner clone is the only way to back up mac dev workstations that boots straight into your exact toolchain.

An external SSD + CCC = a spare dev box

One Thunderbolt SSD plus carbon copy cloner mac free equals a working developer Mac waiting in your bag. On the day yours fails — borrow a colleague's MacBook, plug in the SSD, boot from it, finish the sprint. That is the entire value proposition.

iCloud doesn't sync your toolchain Xcode, Homebrew, Docker, node_modules, ssh keys — none of it.
Reinstall is a two-day job Re-cloning all repos, re-issuing ssh keys, restoring database fixtures — full week gone.
Soldered SSD = no recovery Apple Silicon storage cannot be transplanted. CCC clone is the only backup that survives the failure.

A mac hard disk clone made by CCC is the cheapest insurance any engineer can buy: one external SSD, one free download, ten minutes of setup, indefinitely automatic afterwards. The cloning software has been the trusted carbon copy cloner for mac answer since 2002 because it does one job perfectly — boot the backup, keep working, recover the failed box later.
