A phone backup is the single most valuable thing you can do before something goes wrong. A cracked screen, a stolen phone, water damage, a failed update, or just upgrading to a new device — in every scenario, having a current backup means you lose nothing. Without one, you lose everything that was not synced somewhere else: photos, text messages, app data, notes, health data, and settings that took years to accumulate.
iPhone backup methods
iCloud backup
iCloud backup is the easiest method because it runs automatically every night when your phone is plugged in, locked, and connected to Wi-Fi. It captures almost everything: app data, device settings, home screen layout, iMessage and SMS history, photos and videos (if iCloud Photos is enabled), purchase history, ringtones, and Visual Voicemail.
To enable or verify iCloud backup:
Go to Settings, tap your name at the top, then iCloud
Tap iCloud Backup
Toggle on Back Up This iPhone
Tap Back Up Now to run an immediate backup
The main limitation is storage. Apple gives you 5GB free, which is not enough for most people once photos are included. If your backup fails with a storage full message, you have three options:
Buy more iCloud storage. 50GB is $0.99 per month, 200GB is $2.99, and 2TB is $9.99. For most people, 50GB or 200GB is sufficient
Exclude large apps from the backup. Go to Settings, your name, iCloud, Manage Account Storage, Backups, tap your device, and toggle off apps with large backup sizes. Games with offline data are often the biggest consumers
Use iCloud Photos separately. If photos are your biggest data category, enable iCloud Photos (Settings, Photos, iCloud Photos) and choose Optimize iPhone Storage. Photos sync to iCloud independently of the device backup, and you can exclude them from the backup itself
Computer backup with Finder or iTunes
Backing up to a Mac (Finder in macOS Catalina and later) or a Windows PC (iTunes) creates a complete local copy of your iPhone on the computer's hard drive. This backup includes everything iCloud backup includes, plus additional data like saved passwords and Health data if you check the Encrypt Local Backup option.
Connect your iPhone to the computer with a USB or USB-C cable
Open Finder (Mac) or iTunes (Windows) and select your phone
Under Backups, select Back up all of the data on your iPhone to this Mac (or This computer in iTunes)
Check Encrypt local backup and set a password. This is important: encrypted backups include passwords, Wi-Fi settings, Health data, and call history that unencrypted backups skip. Write down the encryption password — if you forget it, the backup is unusable
Click Back Up Now
Local backups have no storage limits beyond your computer's disk space, so they capture everything regardless of size. The downside is that they only run when you manually connect the phone and initiate the backup, so they can become stale if you do not do it regularly.
Use both methods together
The strongest approach is iCloud backup running nightly for continuous protection, plus a local encrypted backup every week or two for a complete snapshot that includes passwords and Health data. This way you are covered whether you lose your phone (iCloud backup restores to any new iPhone over Wi-Fi) or need to restore data that iCloud does not include.
Android backup methods
Google One backup
Google's built-in backup for Android covers apps and app data, call history, contacts, device settings (including Wi-Fi passwords and permissions), SMS and MMS messages, and photos and videos (via Google Photos). It runs automatically when the phone is idle, charging, and connected to Wi-Fi.
To enable or verify:
Go to Settings, Google, All services, Backup (the path varies slightly by manufacturer)
Make sure Back up to Google One (or Back up by Google One) is toggled on
Tap Back up now to run an immediate backup
Google provides 15GB of free storage shared across Google Drive, Gmail, and Google Photos. If you need more, Google One plans start at $1.99 per month for 100GB.
Google Photos
Photos and videos are often the most irreplaceable data on a phone. Google Photos backs up your camera roll to the cloud continuously when enabled:
Open Google Photos, tap your profile picture, then Photos settings, then Backup
Toggle Backup on
Choose backup quality: Original quality uses your full storage quota, Storage saver compresses photos slightly (still very good quality) to use less space
Google Photos backup is independent of the Google One device backup. Even if you never enable the full device backup, having Google Photos backup on means your photos are safe.
Samsung Cloud (Samsung devices)
Samsung phones have an additional backup layer through Samsung Cloud. It backs up the Samsung-specific features: home screen layout, Samsung apps (Notes, Calendar, Contacts, Samsung Internet bookmarks), device settings, and call and message logs. It does not replace Google backup — it supplements it.
To check: Settings, Accounts and backup, Samsung Cloud, Back up data. Samsung provides 5GB free.
Local backup to a computer
Android does not have a single universal local backup method equivalent to iTunes. Options vary by manufacturer:
Samsung Smart Switch: Install Smart Switch on your computer, connect the phone via USB, and click Backup. Creates a complete backup including apps, settings, messages, and media. This is the closest Android equivalent to an iTunes backup
Direct file copy: Connect any Android phone to a computer via USB, select File Transfer mode on the phone, and copy the DCIM folder (photos), Download folder, and any other folders you want to preserve. This only copies files you can see — not app data, settings, or messages
Pixel: Google does not offer a dedicated desktop backup tool. Rely on Google One cloud backup plus manual file copies for anything not covered
What backups do NOT cover
Both iPhone and Android backups have blind spots you should be aware of:
Authenticator app codes. Google Authenticator (older versions without cloud sync), Microsoft Authenticator, and similar apps store two-factor authentication codes locally. If you lose your phone without backing up these codes separately, you can be locked out of accounts. Export your codes or use an authenticator that supports cloud sync
App-specific data stored only locally. Some apps store data only on the device and do not include it in backups. Check whether apps you depend on (note-taking apps, journaling apps, health tracking) have their own sync or export option
WhatsApp message history requires its own backup within the app (Settings, Chats, Chat backup) to Google Drive (Android) or iCloud (iPhone). It is not included in standard device backups
Downloaded music and offline content from streaming apps (Spotify, Netflix, YouTube). These must be re-downloaded after a restore — they are DRM-protected and cannot be backed up
Banking and payment apps often require re-authentication after restoring to a new device regardless of backup. Have your login credentials ready
How often to back up
With cloud backups enabled and running automatically, your data is protected every night. For local backups, a reasonable schedule depends on how much irreplaceable data you generate:
Weekly: If you take a lot of photos, receive important text messages, or use your phone for work notes and documents
Monthly: If you primarily use cloud-synced apps (Gmail, Google Docs, iCloud) and your phone is mostly a window to cloud data rather than storing unique data locally
Before any major change: Always run a manual backup before a major OS update, before a repair, before travel, or before switching to a new phone
