# Time Machine alternatives for Mac, and what each one is for

People look for a Time Machine alternative for three different reasons - a dead Mac, a folder broken an hour ago, or one file's earlier state - and no single tool answers all three, so the useful question is which layer you are missing.

## In short

- Time Machine answers "my Mac died" well and "I broke this an hour ago" badly, so the usual right answer is to keep it and add a layer rather than replace it.
- With Back Up Automatically on, macOS keeps hourly local APFS snapshots of the startup disk for 24 hours, which is why a restore often works with the backup drive unplugged, and why it rarely reaches back a week.
- Dropbox, Google Drive and iCloud Drive cover one folder, propagate deletions, and restore per file. iCloud Drive has no general version history at all: its 30-day Recently Deleted is for files you deleted.
- Backblaze and Arq cover fire and theft, Carbon Copy Cloner covers being back at work today, and folder version history covers the hour you just lost. Most people need two of the four.

## Three different questions people call "backup"

People go looking for a Time Machine alternative for one of three reasons, and
they need different software each time.

**"My Mac died."** You need a second copy of everything, somewhere the first
copy's failure cannot reach. Ideally two: one in the building for speed, one out
of it for fire and theft.

**"I broke this an hour ago."** Nothing is lost, nothing failed. One folder is
in the wrong state because a find-and-replace went too far, a sync half-finished
or a script renamed everything. What you want is the folder as it was at 14:20,
not a restore of the disk.

**"I need the version from last month."** A specific file, a specific earlier
state, and no idea exactly which day.

Time Machine answers the first well, the third adequately and the second badly.
That is not a flaw in it - it was built for the first - but it is why the honest
answer to "what should replace Time Machine" is usually "nothing, add a layer
next to it".

## What Time Machine is actually good at

It is free, it is already on your Mac, and it does the hard part: a complete,
bootable-adjacent copy of the whole disk with an interface non-technical people
can use under stress. Nothing on this page replaces that.

Two details are worth knowing because they explain most of the complaints. With
Back Up Automatically on and the disk formatted APFS, macOS takes a **local
snapshot** of the startup disk roughly every hour and keeps it for 24 hours,
plus one snapshot of the last successful backup. That is why Time Machine can
often go back an hour with the backup drive unplugged - and why it usually
cannot go back a week. You can see them with `tmutil listlocalsnapshots /`.

Those snapshots are also most of what System Settings reports as **purgeable**
space. macOS counts it as available and releases it when something needs the
room, which is correct behavior presented confusingly, and it is why no
third-party app can "free" it for you.

The limits, then: hourly granularity, whole-disk scope, and a restore
experience aimed at the disk rather than at one folder.

## Where the real alternatives win

**Backblaze** is the offsite answer: unlimited continuous backup of one Mac for
about $99 a year, restores by download or by a posted drive. It wins on the
scenario Time Machine cannot cover at all, which is the drive and the backup
drive being in the same room during the same flood.

**Arq** is the same idea with your own storage behind it - S3, Backblaze B2,
Wasabi, a NAS - and end-to-end encryption you hold the keys for. Arq Premium is
$59.99 a year with 1 TB included and covers five machines; Arq 7 is $49.99 once
if you bring your own bucket. Both rise on 1 September 2026, to $69.99 and
$59.99. It wins on control.

**Carbon Copy Cloner** and **SuperDuper** are not incremental backup at all.
They make a full, mountable copy of a volume, which is the fastest way back from
"this Mac is dead and I have a deadline". CCC is about $50, one-time, and its
snapshot navigator makes it a competent Time Machine substitute too.

**ChronoSync** is the one to reach for when the job is really scheduled
one-directional sync between machines and volumes rather than backup.

None of the five is a version history. They all answer "my Mac died", at
different distances and different prices.

## Sync is not history

![Retrace's list of watched folders, each with its history and any files something was put on top of](https://swiftfox.studio/retrace/listing/shot-1.jpg "A sync folder covers the files inside it. Everything else on the disk is somebody else's problem.")

Dropbox, Google Drive and iCloud Drive get counted as backup because they
usually do get your file back, and they are worth checking first for anything
inside them. But the shape is wrong in three ways.

They cover **one folder**. Everything outside the synced tree - which for most
people is most of their work - is not in scope.

Deletion **propagates**. Delete on the Mac, it is gone on the server; the
recovery window is a rubbish bin with a deadline, not a copy. Dropbox holds
versions 30 days on Basic and Plus, 180 on Professional. Google Drive keeps a
version 30 days or until 100 newer ones exist, unless you clicked Keep forever.
iCloud Drive does not offer general version history at all: its 30-day Recently
Deleted recovers files you deleted, not the file you saved over.

And restoring is **per file**. Dropbox Rewind can roll a folder back, on paid
plans, which is the exception that proves the point: everybody else makes you
repair a broken folder one file at a time.

## The layer none of them covers

![A folder's history in Retrace as a day-banded timeline, with each moment saying which files changed](https://swiftfox.studio/retrace/listing/shot-2.jpg "Seconds after a save rather than once an hour, and the unit you put back is the folder at a moment.")

That leaves the second question - "I broke this an hour ago" - with no good
answer, which is what [Retrace](https://swiftfox.studio/apps/retrace) is for. You right-click a folder
in Finder and switch history on. A few seconds after you stop editing a file it
saves a copy, and because those copies are APFS clones sharing their data with
the original, taking one costs effectively nothing.

The unit of restore is the **folder at a moment**, not one file, and the rewind
captures the folder's current state before it changes anything, so undoing the
rewind is just rewinding back. Everything stays on the same disk and on the same
Mac: no account, no upload, and it works with the network off.

Which is also the honest limit. Same disk means a dead drive takes the history
with it, so Retrace is a layer over a backup and never a substitute for one. It
is covered feature by feature in
[how to recover an overwritten file on a Mac](https://swiftfox.studio/handbook/recover-an-overwritten-file-on-mac).

## Side by side

| Tool | Answers | Copy lives | Granularity | Cost |
| --- | --- | --- | --- | --- |
| Time Machine | My Mac died | External disk, plus 24h of local snapshots | Hourly | Free |
| Backblaze | Fire, theft, flood | Their cloud | Continuous | ~$99/year |
| Arq | Fire, theft, flood | Your bucket or NAS | Scheduled | $59.99/year, or $49.99 once |
| Carbon Copy Cloner | Back to work today | A mountable clone volume | Scheduled | ~$50 once |
| Dropbox, Drive, iCloud | The synced folder | Their server | Per save, per file | Storage plan |
| Retrace | I broke this an hour ago | Same disk, same Mac | Per save, per folder | $8.99 once |

Most people should end up with two rows, not one: something that answers the
first column's first line, and something that answers its last. The two failures
have nothing in common except the word backup.

One thing every row shares is that it needs free disk space, and a Mac with a
full disk quietly stops backing up. If that is the actual problem,
[Sweep](https://swiftfox.studio/apps/sweep) files and cleans the folders you point it at, and there is
a survey in [free up disk space on a Mac](https://swiftfox.studio/blog/free-up-disk-space-on-mac).

## Frequently asked questions

### Do I still need Time Machine if I use something else?

Almost certainly yes. Time Machine is the only free, built-in, whole-disk answer to a Mac that has died, and its restore flow is the one non-technical people can follow under stress. Everything else on this page either sits next to it, covering a case it was never built for, or duplicates it somewhere safer, like offsite.

### What are Time Machine local snapshots?

With Back Up Automatically on and an APFS startup disk, macOS takes a snapshot of that disk roughly every hour and keeps it for 24 hours, plus one snapshot of the last successful backup. They live on the internal disk, which is why entering Time Machine often works with the backup drive unplugged. You can list them with tmutil listlocalsnapshots / and macOS deletes them on its own when it needs the room.

### Is Dropbox or iCloud Drive a backup?

Not really. They cover only what is inside the synced folder, a deletion on your Mac propagates to the server, and recovery is per file with a deadline. Dropbox keeps versions for 30 days on Basic and Plus and 180 on Professional; Google Drive keeps one for 30 days or until 100 newer versions exist. iCloud Drive has no general version history: its 30-day Recently Deleted recovers files you deleted, not a file you saved over.

### How do I put one folder back to how it was yesterday?

Time Machine can restore a folder from its last hourly snapshot, which is the closest built-in answer. If the change happened between snapshots, or the folder is not on a backed-up volume, nothing built in reaches it. That is the gap a local folder version history fills, by capturing seconds after each save and restoring the folder as a whole rather than file by file.

### Does keeping version history fill up the disk?

It is the standard failure of the category, and it comes from keeping rather than from capturing. On APFS a new version can be a copy-on-write clone that shares its data with the original and costs almost nothing to take, so the thing to check before installing anything is whether it thins old versions by age and lets you set a ceiling you can see.

### What do these cost?

Time Machine is free. Backblaze is about $99 a year for unlimited backup of one Mac, Arq Premium $59.99 a year with 1 TB included or Arq 7 $49.99 once if you bring your own storage, both rising on 1 September 2026, and Carbon Copy Cloner about $50 as a one-time license. Retrace is $8.99 one-time with a 30-day trial that needs no card and no email.
