iPhone Backup Software Comparison: iCloud, Encrypted Local, and Third-Party Tools

A backup is the single thing that turns an iPhone disaster — a failed update, a lost phone, or an IPSW restore that wipes the device — into a minor inconvenience. This guide compares the real options for backing up an iPhone: Apple's free iCloud and local backups, and the third-party tools that build on them. The framing that matters most is what actually survives a restore, because that depends entirely on the backup type you chose. If you want the rationale for backing up before a firmware restore, see why you should always back up before installing an IPSW; this article is about which backup to use.

Start here: what Apple already gives you free

• iCloud Backup. Automatic over Wi-Fi, restores during device setup. It backs up app data and device settings that aren't already synced to iCloud, plus your Apple Watch backup. The catch is storage: iCloud gives you 5 GB free, shared across backups, iCloud Photos, and iCloud Drive — most people need a paid iCloud+ tier for a full backup.
• Encrypted local backup (Finder / Apple Devices app / iTunes). Free, limited only by your computer's disk. Crucially, you must turn on Encrypt local backup — it is off by default — and doing so is what preserves saved passwords, Wi-Fi, Health, website history, and call history.

The detail that decides everything: what survives a restore

After an IPSW restore wipes the device, what you get back depends on the backup type:

This is the single most useful thing to know: an unencrypted local backup silently omits your Health data and saved passwords. For passwords specifically, a dedicated manager keeps them independent of backup type — see the best password manager for iPhone.

The methods, one by one

iCloud Backup — the hands-off baseline

iCloud Backup runs automatically over Wi-Fi and restores during setup, which makes it the easiest option to live with. It captures app data and settings not already synced to iCloud, and your Apple Watch backup rides along. Its real limit is the 5 GB free tier shared with Photos and Drive — a full device backup almost always needs a paid iCloud+ plan. Data already synced to iCloud (Contacts, Notes, Messages in iCloud, iCloud Photos) isn't duplicated in the backup because it already lives in iCloud.

Finder / Apple Devices app — the complete free option

A local backup to a Mac (Finder) or Windows PC (Apple Devices app, or iTunes on older systems) is free and as complete as it gets — if you enable Encrypt local backup. Encryption is off by default, and only an encrypted backup includes saved passwords, Wi-Fi, Health, website history, and call history. Store the encryption password somewhere safe: without it, the backup cannot be restored.

iMazing — Apple's backup format with a better interface

iMazing uses Apple's own iOS backup protocol and AES-256 encrypted-backup format, then adds what Apple's tools lack: browsing and extracting individual items, selective restore without wiping the phone, multiple archived snapshots over time, and automatic wireless backups (free for personal use via iMazing Mini). It doesn't capture more than Apple's format allows — Apple decides what a backup contains — but it makes that backup far more usable. Paid license with a free trial; macOS and Windows. See imazing.com.

AnyTrans (iMobie) — backup plus transfer

AnyTrans combines local backups (including "Air Backup" over Wi-Fi to your computer) with device-to-device transfer and selective export of photos, messages, and more. It's aimed at people who move data between devices as much as they archive it. Paid, with subscription and lifetime options; macOS and Windows. See imobie.com/anytrans.

What survives an IPSW restore — and what to do after

An IPSW restore erases the iPhone and reinstalls firmware, so everything you get back comes from your backup. Restore the backup during setup; an encrypted local backup returns the most (including passwords and Health). If you restored without a usable backup and need specific items back, that's a different job — see Best iPhone Data Recovery Software, or for photos specifically, How to Recover Deleted Photos from iPhone. Browse firmware for your model on the iPhone downloads page.

Frequently asked questions

Is iCloud Backup enough on its own?

For many people, yes — if you pay for enough iCloud+ storage. The 5 GB free tier rarely fits a full backup. Pairing iCloud with an occasional encrypted local backup gives you a free, complete fallback that doesn't depend on your storage plan.

What's the difference between an encrypted and unencrypted backup?

Only an encrypted local backup includes saved passwords, Wi-Fi settings, Health data, website history, and call history. An unencrypted backup silently leaves those out. Encryption is off by default, so you must turn on "Encrypt local backup" — and keep the password, or the backup can't be restored.

What does a backup not include?

Backups don't duplicate data already synced to iCloud (Contacts, Notes, Messages in iCloud, iCloud Photos), and no backup stores your Face ID, Touch ID, or device passcode. Face/Touch ID and passcodes are re-created on the device, not restored.

How much iCloud storage do I need to back up my iPhone?

It depends on your device's data, but it is almost always more than the free 5 GB — which is why a full iCloud backup usually requires a paid iCloud+ tier. Settings shows the estimated backup size before you commit.

Does restoring a backup overwrite my current data?

Restoring a backup replaces the device's current contents with the backup's contents, so anything created after that backup is lost. Restore is a point-in-time snapshot, not a merge.

Do third-party backup tools capture more than Apple's backup?

No. Tools like iMazing and AnyTrans use Apple's own backup format, so they capture what Apple's format allows. Their advantage is usability: selective restore, archived snapshots, wireless automation, and browsing individual items.

Can I back up an iPhone that won't turn on?

No. Backups read from a functioning device. If the iPhone won't boot, you may be able to revive it with a restore, but any data not already backed up is at risk. This is why backing up before problems occur matters.

Is a local backup safer than iCloud?

Neither is strictly "safer" — they're complementary. A local encrypted backup keeps a complete copy under your control; iCloud adds off-site, automatic protection. Using both is the most resilient setup.

Backing up preserves a copy of one device; if instead you are setting up a new iPhone, that is a different task — see the iPhone transfer software comparison.

Conclusion

The best iPhone backup isn't a specific app — it's the right combination: an encrypted local backup for completeness and a paid iCloud tier for hands-off, off-site protection. Reach for iMazing or AnyTrans when you want selective restore, archived snapshots, or wireless automation on top of Apple's format. Whatever you choose, make sure it's encrypted and made before you need it.
