time machine vs icloud: which should you use on a mac?
time machine and icloud do different jobs. apple calls time machine the built-in backup feature of your mac: it copies your files to a drive you connect or a disk on your network, and deletes the oldest backups when that disk is full. apple's backup page files icloud under sync and store data, and with desktop & documents folders in icloud drive, deleting a file on one device removes it from every device signed in to the same apple account.
in our view, most mac users are better off with both. apple lists both as ways to protect your files.
this guide follows apple's time machine, backup and icloud drive support pages and the current mac user guide, as of november 2026.

what is the difference between time machine and icloud?
time machine makes backups, and icloud syncs and stores. this table follows apple's how to back up your mac page, published october 2, 2025, and its time machine article, published october 16, 2026.
| time machine | icloud | |
|---|---|---|
| what apple calls it | the built-in backup feature of your mac | sync and store data with icloud |
| where the copy lives | a usb, thunderbolt or other storage device, or a disk on your network | icloud, using your icloud storage plan |
| what it covers | all your files, apps, music, photos, email and documents included | contacts, calendars, photos, videos, notes, passwords and more, plus files you put in icloud drive |
| older versions | hourly, daily and weekly backups, oldest deleted when the disk is full | not described on the apple pages we used |
| when you delete a file | apple says your backup can recover deleted files | for desktop and documents files, it deletes on every device with the same apple account |
| getting it back | restore from a backup in time machine | recently deleted on icloud.com |
how does time machine back up a mac?
time machine backs up to a storage device you connect, such as a usb drive or thunderbolt drive. apple says it keeps hourly backups for the last 24 hours, daily ones for the last month and weekly ones for every month before that, and deletes the oldest once the backup disk fills up.
apple's backup disks page lists where time machine can save backups: an external storage device, another mac shared on your network (apple recommends this only when both macs use macos 11 or later), a nas device that supports time machine over smb, or an airport extreme base station or airport time capsule. apple says the airport options are no longer recommended, because afp isn't supported in macos 27 or later. icloud is not on that list.
to set it up in macos ventura 13 or later, apple gives these steps:
- connect the drive, ideally with at least twice your mac's storage capacity, and use it only for time machine backups.
- choose apple menu > system settings, click general, then click time machine.
- click add backup disk, select the drive, then click set up disk. your mac might ask to erase it first.
- turn on encrypt backup if you want a backup password. apple says you will need it to restore files later.
after setup, apple says backups start right away. later backups copy only files changed since the last one, and you can start one by hand with back up now in the time machine menu bar menu.
does icloud back up your mac?
apple says icloud keeps some kinds of data automatically backed up, and in our read it presents icloud mainly as sync and storage. apple's backup page says icloud keeps your contacts, calendars, photos, videos, notes, passwords and more safe, backed up automatically and available wherever you are. it also says to use icloud drive for other files, including your desktop and documents folders.
apple's desktop and documents guide adds two limits:
- deleting a file on one device removes it from every device signed in to the same apple account.
- icloud drive won't upload imovie, photos or aperture libraries from those folders to your other devices.
to turn it on, choose apple menu > system settings, click your name, then icloud, then drive (or icloud drive). check that sync this mac is on, turn on desktop & documents folders, and click done.
how do you get a file back from each one?
you get a file back from time machine by restoring it from a backup, and from icloud through recently deleted on icloud.com. for time machine, apple's mac user guide says to open the folder the item was in, open time machine with spotlight, use the arrows to move through backups, select the item and click restore.
restored items return to their original location. many apps also offer file > revert to > browse all versions.
for icloud, apple's icloud.com recovery guide says you can recover files deleted in the past 30 days from icloud drive and other apps. for icloud drive, go to icloud.com/iclouddrive and select recently deleted; for other apps, apple points to icloud.com/recovery. apple adds that you can't recover or restore files you permanently remove. for every route, including the trash, see how to recover deleted files on mac.
which one should you use?
our view: use time machine as the backup and icloud for sync. time machine is the one apple ties to older versions and to restoring a mac, and icloud is the one that keeps the same files on your iphone, ipad and other macs. apple's ways to back up or protect your files page lists both, along with other options.
our read: of the apple pages we used, only the time machine ones describe getting back older versions.
what does neither one keep?
both keep files, and in our read neither keeps a record of what you looked at on screen, such as a message you read once or a page you closed.
in microsoft's work trend index, published may 9, 2023, which surveyed 31,000 full-time employed or self-employed workers in 31 markets, 62% of respondents said they struggle with spending too much of their workday searching for information, and 86% said they were looking for ai to help find the information and answers they need.
where does remynd fit?
remynd records your screen, runs ocr locally with apple vision, and keeps a searchable index on your computer. text comes from the focused window only, and video covers windows you have not excluded.
you can exclude apps and sites, and private browser windows are excluded by default. press control space to search in plain language, refine by app, date or source, and jump to an exact moment, provided remynd was running then, the window was not excluded and, for text, it was the focused window. it needs macos 14 or later on an apple silicon mac.
