A person texting on a smartphone, with chat messages visible on the screen.
WhatsApp keeps your chats on your phone, not on its servers, so a lost, stolen, or replaced phone can wipe years of conversations in a single moment.
The fix is a cloud backup, and WhatsApp builds one into the app on both Android and iPhone, using Google Drive on Android and iCloud on iPhone.
This guide walks through both setups, plus restoring a backup and fixing the most common failures.
Key Highlights of WhatsApp Chat Backup
Android uses Google Drive: On Android, backups upload to your Google account, and since 2024 they count toward your 15 GB of free Google storage.
iPhone uses iCloud: On iPhone, backups upload to iCloud, and they count toward your 5 GB of free iCloud storage unless you pay for more.
Same number, same account: A backup restores only to the same phone number and the same Google or Apple account that created it.
Encryption is optional but worth it: End-to-end encrypted backup protects your chats in the cloud, but losing its password or 64-digit key makes restore impossible.
One backup replaces the last: Each new cloud backup overwrites the previous one, so there is no archive of older backups to roll back to.
Backups expire if neglected: Google may delete an Android backup that has not been updated for five months, so automatic backups are the safest habit.
Before You Start: What a WhatsApp Backup Covers
A WhatsApp backup saves your messages, photos, videos, voice messages, and documents, so a new phone can pick up exactly where the old one stopped.
It does not save everything, though, and media you exclude, such as videos, will simply be missing after a restore, so choose your settings deliberately.
You also cannot open a backup like a document, because it lives in a hidden app folder that only WhatsApp itself can read and restore.
Finally, backups do not move between platforms on their own, so an Android backup cannot restore directly onto an iPhone, or the other way around.
How to Back Up WhatsApp to Google Drive on Android
Before you start, sign in to a Google account on your phone, install Google Play services, and check that your Google storage has room for the backup.
Since the first half of 2024, WhatsApp backups on Android count toward the 15 GB of free storage shared by Gmail, Google Drive, and Google Photos.
That change matters most for heavy users, because years of photos and videos inside chats can quietly fill a free account and stall future backups.
Open Chat backup: Open WhatsApp, tap the three-dot menu in the top-right corner, then go to Settings, Chats, and Chat backup.
Choose your Google account: Tap Back up to your Google Account, pick the account you want to use, or tap Add account to sign in to a new one.
Set the frequency: Tap Back up to Google Drive and choose Daily, Weekly, or Monthly, or leave it on Never if you only want manual backups.
Decide about videos: Turn on Include videos only if you have storage to spare, because videos are usually the largest part of any WhatsApp backup.
Back up now: Tap Back up to start an immediate backup, stay on Wi-Fi while it uploads, and wait for the progress bar to finish before closing the app.
If you back up over mobile data, a large backup can burn through your data plan quickly, so Wi-Fi is the safer default for most people.
How to Back Up WhatsApp to iCloud on iPhone
On iPhone, WhatsApp backs up to iCloud instead of Google Drive, and the steps are similar but live in a different settings path inside iOS.
First, open your iPhone Settings, tap your name at the top, tap iCloud, and make sure iCloud Drive and WhatsApp are both switched on.
Backups count toward iCloud storage, and the free tier is only 5 GB, so a media-heavy backup can fill it fast unless you buy extra space.
Open Chat Backup: Open WhatsApp, tap Settings in the bottom-right corner, then tap Chats and Chat Backup to see your backup status.
Back up now: Tap Back Up Now to upload a fresh copy immediately, and keep WhatsApp open on Wi-Fi until the upload completes.
Set Auto Backup: Tap Auto Backup and choose Daily, Weekly, or Monthly, so future backups happen automatically without you remembering them.
Include or exclude videos: Toggle Include Videos on only if you have iCloud room to spare, since videos inflate the backup size more than anything else.
Apple recommends having at least 2.05 times the backup size free on both iCloud and your device, so a 1 GB backup needs roughly 2.05 GB free.
Turn On End-to-End Encrypted Backup
By default, your chats are end-to-end encrypted while you send them, but the cloud backup itself is not encrypted unless you switch that protection on.
Turning it on adds a password or a 64-digit encryption key, and neither WhatsApp nor Google nor Apple can recover that key if you lose it.
Store the password or key somewhere safe outside your phone, such as a password manager, because without it the backup can never be restored.
Find the setting: In WhatsApp, go to Settings, Chats, Chat backup, then tap End-to-end encrypted backup and follow the on-screen prompts.
Choose a password or key: Create a strong password you will remember, or use the 64-digit key option and save that key somewhere safe immediately.
How to Restore a WhatsApp Backup on a New Phone
Restoring works only on the same platform that made the backup, so a Google Drive backup restores to Android and an iCloud backup to iPhone.
Sign in to the same Google or Apple account first, then install WhatsApp, verify the same phone number, and tap Restore when WhatsApp finds the backup.
Messages restore first and media follows in the background, so do not panic if photos and videos take longer to appear after setup.
Moving between Android and iPhone needs a different tool, either Move to iOS or Switch to Android, and it must run during first-time setup.
Android also keeps a local backup on the phone itself, stored under Android/media/com.whatsapp/WhatsApp/Databases on newer Android versions each night.
Troubleshooting Common Backup Problems
Most backup failures come down to a handful of causes, and each one has a straightforward fix you can check before trying anything drastic.
Backup will not start: Check your Google or iCloud storage first, because a full account is the most common reason backups stop without a clear warning.
Wrong account signed in: A backup tied to a different Google or Apple account will never appear, so confirm the account matches the one that made it.
Restore prompt never appears: Make sure you verified the same phone number, since WhatsApp ties every backup to the number that created it.
Backup is too large: Turn off Include videos, delete large forwarded videos with WhatsApp's Manage storage tool, then run a fresh backup.
Old backup disappeared: Google may delete Android backups untouched for five months, so re-enable automatic backups and make a fresh one now.
Encrypted backup will not restore: Without the exact password or 64-digit key, an encrypted backup cannot be opened, and WhatsApp cannot reset it for you.
Frequently Asked Questions
Does WhatsApp back up automatically?
Yes, once you pick a frequency such as Daily, WhatsApp uploads new chats on that schedule, and you can also tap Back up at any time for a manual copy.
Do WhatsApp backups count toward my storage?
Yes, on both platforms, since Android backups count toward your 15 GB Google allowance and iPhone backups count toward your 5 GB iCloud allowance.
Can I restore a Google Drive backup to an iPhone?
No, not directly, because Google Drive backups restore only to Android and iCloud backups only to iPhone, so cross-platform moves need a transfer tool.
What happens if I change my phone number?
A backup is tied to the number that created it, so verify that same number on the new phone first, or use WhatsApp's Change number feature before switching.
Can I back up without Google Drive or iCloud?
On Android, WhatsApp also saves a local backup on the phone each night, and you can copy the WhatsApp folder to a computer as an extra safety net.
How often should I back up?
Daily is the safest choice for most people, because it limits what you can lose to a single day, while weekly backups risk losing up to seven days.
Set automatic backups on today, confirm the first one completes, and store your encryption password safely, because a backup you never test is only a hope.
