Best Backup Software for Mac

Every Mac user eventually needs a backup, usually on the worst possible day. The tricky part is choosing between tools that protect against different disasters. A backup that saves you from an accidental deletion cannot save you from a stolen laptop, and the reverse is also true.

This guide compares the main approaches and the best-known tools in each, so you can match the tool to the problem.

Quick recommendations#

These are matched to use cases, not ranked by a score. They are provisional until hands-on testing is complete.

Comparison table#

First, understand the three kinds of backup#

Most confusion disappears once you separate these:

• Versioned backup keeps multiple past versions of your files so you can go back in time. Time Machine and Arq work this way.
• Clone makes an exact copy of a disk at a moment in time. It's fast to restore from, but only gives you one state unless you keep several clones.
• Cloud backup sends encrypted copies to servers elsewhere, protecting you from fire, theft, and flood.

The long-standing guideline is the 3-2-1 rule: three copies of your data, on two kinds of storage, with one copy offsite. No single tool below meets all three on its own, which is why many people combine two.

Individual product notes#

Each section below describes what the tool is for, based on its documented approach. Pricing and our testing status come from the data file behind the panel, never from memory.

Time Machine#

Time Machine is Apple's built-in backup. You point it at an external drive or a compatible network disk, and it quietly keeps versions of your files, so you can go back to yesterday's draft or last month's folder. It also helps you move to a new Mac.

What it's good at: zero cost, deep integration with macOS, and straightforward file-by-file restores.

Carbon Copy Cloner#

Carbon Copy Cloner is built around tasks: you choose a source, a destination, and a schedule, and it copies. It's known for making bootable clones and for giving more control than Time Machine over what gets copied and when.

What it's good at: scheduled clones, fine-grained control, and recovery options that don't depend on Time Machine.

SuperDuper!#

SuperDuper! has long been the simple clone tool: pick a source and a destination, click copy. It's designed to be hard to use wrongly.

What it's good at: straightforward full-disk clones with little to configure.

Arq#

Arq backs up to storage you choose, whether a local disk, a network device, or a cloud storage provider, and encrypts the data with a key you control. It's popular with people who want to avoid being locked into one provider's storage.

What it's good at: flexibility. You choose where backups go and how long they are kept.

Backblaze Personal Backup#

Backblaze Personal Backup runs in the background and continuously sends your files to Backblaze's cloud. It is designed to be the offsite copy: install it, let the first upload finish, and it keeps up.

What it's good at: offsite protection with almost no setup and no extra hardware.

Best for specific situations#

• You only want one thing, and it should be free: Time Machine, with an external drive. It covers a real baseline, and an offsite copy completes the strategy.
• You edit video or have a huge library: a local backup (Time Machine or a clone) for fast restores, plus an offsite copy for safety.
• You travel with your laptop: an offsite cloud backup, because a bag stolen with the laptop and drive takes both.
• You want a bootable emergency copy: a cloning tool, subject to checking the current limits on your Mac model.
• You care about who holds the keys: an app with client-side encryption and your own storage, such as Arq.

How we test backup software#

When testing is complete, each product will be evaluated on the same checklist, on a current macOS. We record versions and the date for everything.

1. Install and first backup. Time how long setup takes and note permissions requested.
2. Restore a single file. Delete a file, then restore it, and record the steps.
3. Restore a full state. Where the tool claims to support it, recover a whole Mac or volume onto a spare drive.
4. Interrupt it. Unplug the drive or disconnect the network mid-backup and see whether the tool recovers cleanly.
5. Check the claims. Confirm price, retention, and encryption claims against the vendor's documentation on the day.

None of these steps has been completed for this guide yet. That is why the comparison shows no ratings.

Alternatives and combinations#

• Time Machine plus a cloud backup covers local restores and offsite disaster recovery, and is the combination most people should consider.
• A clone plus Time Machine gives you both a fast emergency boot option and version history.
• Manual copies to an external drive work if you do them reliably, but most people don't.

Backup drive problems#

If your backup drive stops appearing, follow how to fix an external SSD not showing up. If the drive came from a Windows PC and Time Machine rejects it, pick the right format and see NTFS software for Mac.

Frequently asked questions#

Is Time Machine enough?#

For many people it is a good start, particularly for recovering from deleted files or moving to a new Mac. It does not protect you against theft, fire, or the drive failing at the same time as your Mac, so adding an offsite copy is wise.

Do I need a bootable clone?#

Only if you want a way to start your Mac from the backup immediately after a failure. If you can wait to restore, versioned backups are enough. Bootable-clone behaviour varies by Mac model, so check before relying on it.

Cloud or local: which is better?#

They solve different problems. Local backups restore faster. Cloud backups survive physical disasters. The safest answer is both.

How often should I back up?#

Continuously or hourly is ideal for work you can't recreate. Time Machine and most cloud tools handle this automatically once set up.

Can I use one external drive for backups and files?#

You can, but a separate drive dedicated to backups is cleaner and avoids accidentally filling it with other files.

Our recommendation#

Until our hands-on testing is complete, we recommend a simple, defensible setup in place of a single winner: use Time Machine to a dedicated external drive, and add an offsite cloud backup. Choose a cloning tool if you specifically need a bootable copy, and Arq if you want control over storage and encryption.
