Apple states that if iCloud Backup is turned off for a device, any backups already stored in iCloud are kept for 180 days before being deleted. That single sentence, from Apple’s own support documentation, is the only expiration window Apple publishes for a consumer’s iCloud backups.
It is a specific, dated number in a part of Apple’s support library that otherwise deals in general reassurance rather than figures, and it answers a question a lot of people assume has no answer at all: what happens to an old backup once you stop backing up.
The 180-day figure, in Apple’s own words
| Key facts | Detail |
|---|---|
| Retention after Backup is turned off | 180 days, then deleted |
| What triggers the clock | Turning off iCloud Backup for that device |
| Source | support.apple.com/en-us/108770 |
| Page last dated | May 1, 2025 |
Apple’s exact wording is that backups are kept for 180 days before deletion once Backup is switched off. Nothing on that page states whether the clock resets if Backup is switched back on and off again, or whether a partial backup is treated any differently from a complete one.

What actually sits inside that backup
Apple’s page on what iCloud backs up lists device settings, Home Screen layout and app organization, purchased ringtones and a Visual Voicemail password, app data for downloaded apps, and, notably, an Apple Watch backup bundled inside the backup of its paired iPhone. iMessage, SMS and MMS messages are included only when Messages in iCloud is switched off, and the same logic applies to photos and videos when iCloud Photos is off.
That last distinction is the one most people get backwards. Anything already syncing through iCloud Photos, iCloud Drive, Notes or Messages in iCloud is not duplicated inside the device backup, because it already lives in iCloud on its own. The 180-day countdown applies to the backup itself, not to that already-synced content, which follows its own storage rules under whichever iCloud+ plan is active.
Where this collides with a storage bill
Apple’s backup instructions include a specific line for the moment it goes wrong: if there is not enough iCloud storage to complete a backup, the onscreen prompt directs a user to buy more iCloud storage. That is the point where the 180-day retention question and iCloud+’s $0.99 to $59.99 monthly pricing tiers meet in practice. A subscriber who declines to upgrade and instead turns off Backup for that device is the exact scenario the 180-day figure is written for.
Backup storage is not the same as device storage
Apple maintains a separate support page distinguishing device storage, the space used on the iPhone or iPad itself, from iCloud storage, the space used by backups and synced content in the cloud. Buying more iCloud storage does not free up space on the device, and freeing up space on the device does not change what an iCloud backup contains. Confusing the two is common enough that Apple gives it a page of its own.
The other route, backing up with a Mac, carries no published retention figure
Apple’s page for backing up with a Mac, dated June 23, 2026, describes a different process entirely: connect the device to the Mac with a cable, allow the accessory to connect, open the Finder, select the device in the sidebar, trust the computer, enter the passcode, then click Back Up Now. Nowhere on that page does Apple state how long a Mac backup is kept once it exists, whether the device is still backing up to it or not. The 180-day figure is specific to iCloud Backup; a computer backup carries no matching number.
| Detail | iCloud Backup | Mac Backup |
|---|---|---|
| Stored where | iCloud | Local drive, via Finder |
| Retention once stopped | 180 days, then deleted | Not stated by Apple |
| Health and Activity data | Included automatically | Only if “Encrypt local backup” is selected |
| “How to back up” page dated | May 15, 2026 | June 23, 2026 |
That Health and Activity line is the sharpest, most consequential difference between the two methods. Apple’s Mac-backup page states plainly: “If you want to save Health and Activity data from your device or Apple Watch, select ‘Encrypt local backup’ and create a password,” adding the warning, “You can’t recover your backup without this password.” An unencrypted computer backup taken before iOS 27 arrives will not carry Health and Activity data at all, a limitation iCloud Backup does not share, since Apple’s page on what iCloud backs up lists an Apple Watch backup as included by default.
Why this is worth checking before Monday
Apple’s documented update sequence lists backing up as the first step, ahead of connecting to power and Wi-Fi. With iOS 27 arriving Monday, September 14, anyone who has ever turned off iCloud Backup and forgotten about it is closer to that 180-day cutoff than they might assume, and Apple’s page gives no warning notification before deletion beyond the countdown itself.
What Apple has not said
- Whether the 180-day clock resets if Backup is turned back on before the window ends.
- Any advance warning Apple sends before a stored backup is actually deleted.
- Whether a partial or interrupted backup is retained on the same 180-day schedule as a complete one.
- Any retention window for a backup stored on a Mac, the way it publishes one for iCloud Backup.
Today is Saturday, September 12, 2026. With iOS 27 shipping Monday, checking Settings for a device’s current iCloud Backup status, on or off, is a two-minute step worth taking before, not after, the update arrives.
