Time Machine still can't back up to iCloud: what to use instead

Updated September 2026: still no way to point Time Machine at iCloud. What has changed is that the alternatives are better, so this post now covers what to use instead.

My MacBook Pro has died twice. Both times Time Machine got my files back, and both times I got lucky, because the backup that saved me was sitting on a drive in the same room as the laptop that failed.

That is the flaw. Time Machine on macOS backs up to a disk you own and can touch. An external drive over USB, or a network volume such as a NAS or another Mac sharing a folder. There is no option to send a Time Machine backup to iCloud, and after all these years there still isn't one.

Why a local-only backup is weaker than it looks

A backup protects you from the thing that destroys the original. Local backups only protect you from one of those things.

Drives fail on their own schedule. A spinning external drive that has been knocked off a desk once is a drive you should not be trusting with the only copy of your documents. Mine has been dropped. I still used it for another year, which was daft.

Then there is the interrupted backup. Unplug during a write, or let the Mac sleep mid-pass, and you can end up with a backup set that appears in Time Machine and fails when you actually ask it to restore. You find this out on the worst possible day. That is the category of failure people never plan for, because a backup that exists feels like a backup that works.

And the obvious one. Fire, flood, theft, or a house move gone wrong takes the laptop and the drive together, because they live in the same bag.

The travel problem

Accidents happen away from home more than at home. That is when the laptop is in a bag, on a train, on a desk that isn't yours. It is also exactly when the backup drive is sitting at home, plugged into nothing.

So the period of highest risk is the period with no recent backup. If you travel for work with a Mac and your only backup is an external drive in a drawer, you are carrying the risk without the cover.

What iCloud actually does, and what it doesn't

This is where a lot of Mac owners get caught, so it is worth being precise.

iCloud Drive with Desktop and Documents Folders turned on keeps those two folders in sync across your devices. That is sync, not backup. If a file is deleted or corrupted on the Mac, the change syncs up. You get 30 days to recover deleted files from iCloud.com, which is a real safety net but a short one, and it does not hold months of versions of a document the way Time Machine does.

iCloud also does not carry your applications, your system settings, or anything outside the folders you have chosen. Restoring a dead Mac from iCloud gives you your files back eventually. It does not give you your machine back in an hour, which is the thing Time Machine is genuinely good at.

So the two are not substitutes. Apple has never claimed they were. The gap is that Apple sells cloud storage, sells a backup tool, and will not let one write to the other.

What I do instead

Two copies, two kinds, and I test one of them.

Time Machine to a local drive stays. It is still the fastest way back from a dead Mac, because Migration Assistant can rebuild a new machine from it, applications and settings included. Nothing cloud-based restores a working Mac that quickly.

Alongside it, an off-site backup that runs without me remembering anything. Backblaze and Arq are the two most people end up on. Backblaze runs unlimited continuous backup from one Mac for a flat subscription and needs no thought after setup. Arq is a licence you buy once and point at storage you already have, including iCloud Drive, Dropbox, Google Drive or an S3-style bucket, which is the closest thing to the feature I originally asked for.

Check the prices yourself before you commit. Both change them, and a stale figure in a blog post is worse than no figure.

The part people skip is the test. Once a quarter, restore one file you actually care about from each backup. Not a screenshot. A real document. A backup you have never restored from is a theory.

If you only change one thing

Get the second copy out of the building. Any method. An off-site service, a second drive at a relative's house that you swap every month, even a folder of your genuinely irreplaceable files in cloud storage.

The local drive is not the weak link because it might fail. It is the weak link because it is in the same room as the Mac.

My own MacBook failure and what it cost me is written up in this account of the 2012 MacBook Pro breaking down, and the machine that replaced it is covered in the 14-inch MacBook Pro write-up. Both of those stories end better because a backup existed.
