How Long Do iCloud Backups Last?

By Jack Smith · Updated March 8, 2026

iCloud keeps your most recent three backups for each device indefinitely, as long as iCloud Backup remains enabled and you have sufficient iCloud storage. However, if a device stops backing up for 180 days (about 6 months), Apple will delete that device's backup. Apple sends an email warning before deletion so you can take action.

How iCloud Backup Retention Works

iCloud Backup is designed as a rolling safety net, not a long-term archive. Here's how Apple manages your backups:

Active devices: iCloud keeps the three most recent backups for each actively used device. Every time your iPhone backs up (daily when plugged in, locked, and on Wi-Fi), the oldest of the three is replaced.
Inactive devices: If a device stops creating new backups for 180 days, Apple marks the backup for deletion and sends you an email notification. You have a grace period to back up the device again before the data is removed.
Manually disabled: If you turn off iCloud Backup for a device, the existing backup isn't immediately deleted but will eventually be removed.

What Triggers the 180-Day Countdown

The 180-day timer starts when your device stops completing iCloud Backups. This typically happens when:

You sell, trade in, or stop using an old iPhone or iPad
Your iCloud storage is full and backups can't complete
You disable iCloud Backup in Settings
Your device is off or disconnected from Wi-Fi for an extended period

The critical thing to understand: if your iCloud storage is full and backups are silently failing, the 180-day clock is already ticking. Check your backup status at Settings > [Your Name] > iCloud > iCloud Backup to see the last successful backup date.

How to Check Your Existing Backups

To see all iCloud Backups associated with your Apple ID:

Go to Settings > [Your Name] > iCloud > Manage Account Storage > Backups. You'll see a list of every device with a backup, along with the backup size and last backup date. Devices you no longer own may still have backups here, consuming your iCloud storage. You can delete old backups you no longer need to free up space.

iCloud Backups vs. iCloud Photos

It's important to distinguish between iCloud Backups and iCloud Photos. Your iCloud Photos library is not a "backup" — it's a continuously synced copy of your photo library. iCloud Photos data is not subject to the 180-day deletion rule. As long as your iCloud subscription is active, your photos remain in iCloud indefinitely. However, if you stop paying for iCloud+ and exceed the free 5 GB tier, Apple may eventually delete data after repeated warnings. See does iCloud backup include photos for more on this distinction.

What Happens If You Run Out of iCloud Storage

If your iCloud storage is full, new backups cannot complete. iOS will show notifications prompting you to upgrade your storage plan. Meanwhile, the last successful backup remains stored. If this situation persists for 180 days without a successful backup, Apple may delete the stale backup. This creates a dangerous gap where you think your data is backed up but it isn't.

To prevent this, either upgrade your iCloud+ plan, reduce backup size by cleaning your photo library with Swype Photo Cleaner, or switch to computer-based backups.

Local Backups Last Forever

Unlike iCloud Backups, backups made to a Mac (via Finder) or PC (via iTunes) have no expiration date. They remain on your computer's hard drive until you manually delete them. If long-term backup retention is important to you, maintaining periodic local backups alongside iCloud is a solid strategy.
