Where the backup is stored on the Android phone: all possible places and how to manage them

Backup on Android is like insurance for your photos, contacts and settings. But where exactly are these copies stored? Many users get lost when they need to find or restore data: either search in the phone’s memory, or in the cloud, or in the manufacturer’s hidden folders. In fact, there may be several storage locations - and they all depend on the method of creating a backup, the Android version and even the smartphone model.

Some copies are created automatically (for example, through Google Account), others manually (via adb backup or third-party utilities like Titanium Backup). At the same time, files can take up gigabytes of memory that you don’t even know about. In this article, we will look at all possible storage locations for backups on Android - from standard to hidden, and also learn how to manage them so as not to clutter your device.

If you have ever tried to free up space on your phone and came across a folder backup or files with the extension .ab, but didn’t know if they could be deleted - this guide is for you. We will also reveal features of backups on Samsung, Xiaomi and Huawei smartphoneswhere manufacturers add their solutions on top of standard Android features.

1. Standard backup storage locations in Android

The basic Android system offers two main backup methods: via Google Account (cloud) and locally on the device. Let's look at both options in more detail.

Cloud copies (Google Drive) is the most common method. When you enable backup in the settings (Settings → Google → Backup), the system automatically saves:

• 📱 Contacts (synchronized s Google Contacts)
• 📅 Calendar data (Google Calendar)
• 📷 Photos and videos (if enabled Google Photos)
• ⚙️ System settings (Wi-Fi passwords, wallpaper, screen brightness)
• 🎮 Data of some applications (if the developer supported the function)

This data is stored on Google servers and does not take up space on the phone. However a complete backup of all applications and their data (as on iOS) Android does not - many apps simply do not support cloud saving.

Local copies are created less frequently, but are also important. For example, with a manual backup via adb backup the file is saved on your computer and not on the phone. However, some system utilities (for example, Samsung Smart Switch or Mi Movercan create temporary copies in the internal memory. They can usually be found along the path:

/sdcard/backup/
/data/data/com.android.backupconfirm/files/

Please note: the folder /data/ is not accessible without root access, so a simple file manager cannot open it.

2. Where are backups stored on Samsung, Xiaomi and Huawei phones? now an integrated solution with

Smartphone manufacturers often add their own backup solutions that work alongside standard Android features. This leads to data duplication and wasted memory.

Samsung uses the service Samsung Cloud (until 2021) and now an integrated solution with Microsoft OneDrive. Local copies created via Smart Switchare stored here:

• 📁 /sdcard/SmartSwitch/backup/ — for backups to a memory card
• 📁 /storage/emulated/0/SmartSwitchPC/ —if the copy was made via a PC

The files have the extension .spb (Samsung Phone Backup) and can weigh tens of gigabytes. They can be deleted manually, but it is better to use it yourself Smart Switch for management.

Xiaomi saves backups through the app Mi Mover to the folder:

/MIUI/backup/AllBackup/

The files here are format .xbk and contain complete images of the system, applications and data. A feature of Xiaomi is that backups are encrypted, so they can only be restored on devices of this brand.

Huawei uses Huawei Backup with saving in:

/Huawei/Backup/

Copies here are divided into two categories:

• 🔄 Full backups (all device data, weighs a lot)
• ☁️ Cloud copies (uploaded to Huawei Mobile Cloud servers)

What to do if the backup folder does not open?

If you are trying to open a backup folder (for example /data/data/com.android.backupconfirm/), but the system displays the error "No access", which means that you do not have root access. Without them, it is impossible to view the contents of system folders. However, you can manage backups through standard Android settings or manufacturer's utilities (Smart Switch, Mi Mover, etc.).

3. Hidden backups: what's taking up space without your knowledge

Many users wonder why their phone suddenly runs out of space even though they haven't downloaded anything. Often automatic backups that the system is silent about are to blame. Here's where they can hide:

1. Google Drive cache

Even if you haven't enabled manual backup, some apps (such as Google Photos or Google One) may create temporary files in:

/Android/data/com.google.android.apps.photos/files/
/Android/data/com.google.android.apps.docs/files/

These folders may weigh several gigabytes, especially if you have the "Original quality" function enabled in Google Photos.

2. WhatsApp and Telegram backups

Messengers automatically save copies of chats:

• 💬 WhatsApp: /sdcard/WhatsApp/Databases/ (files msgstore.db.crypt14)
• 📤 Telegram: /sdcard/Telegram/Telegram Backups/

WhatsApp creates new copies every nightif automatic backup is enabled. Old files are not deleted!

3. System backups from the manufacturer

On phones OnePlus, Oppo or Realme copies can be secretly created through proprietary utilities. data-i="122">saves data in: Oppo Clone Phone saves data to:

/OppoBackup/

These files are not visible in the standard file manager and require special tools for deletion.

4. How to find and delete unnecessary backups

If you decide to free up space, first determine which copies are safe to delete and which are best left alone. Here are the step-by-step guide:

Step 1: Check cloud copies

1. Open Settings → Google → Backup.
2. Click "Manage backups." data-i="133">Remove old or unnecessary devices from the list.
3. Remove old or unnecessary devices from the list.

Step 2: Clean up local backups

Use a file manager (for example, Solid Explorer) to search for folders:

• 🔍 backup
• 🔍 SmartSwitch
• 🔍 MIUI/backup
• 🔍 Huawei/Backup

Delete only those files which you confidently identify as backups. Do not touch folders with unknown extensions (.dat, .tmp) - these may be system files.

Step 3: Clear the messenger cache

In WhatsApp:

1. Open Settings → Chat → Backup.
2. Delete old local copies (the "Delete" button).

In Telegram, go to Settings → Data and memory → Storage location → Clear cache.

Check cloud copies in Google Drive

Delete old WhatsApp backups (older than 7 days)

Empty the /SmartSwitch/ folder on Samsung

View the contents of /MIUI/backup/ on Xiaomi

Remove unnecessary files from /Huawei/Backup/

5. How to transfer a backup copy to another phone

Transferring backups between devices is a common task when changing a smartphone. The method depends on the type of copy:

Cloud copies (Google, Samsung Cloud, Huawei Mobile Cloud)

The simplest option:

1. On the new phone, log in to the same account (Google, Samsung, Huawei).
2. When setting up for the first time, select "Restore from backup" copies."
3. Wait for the process to complete (may take hours if there is a large amount of data).

Please note: Not all data is restored. For example, SMS and call logs are not transferred on all devices.

Local copies (Smart Switch, Mi Mover, adb backup)

To transfer files with extensions .spb, .xbk or .ab:

1. Copy the backup folder to your computer or external drive.
2. Connect a new phone and move the files to the appropriate folder (for example, /SmartSwitch/backup/).
3. Use a proprietary utility (Smart Switch, Mi Mover) for recovery.

Manual backups (Titanium Backup, adb)

These copies are transferred as regular files, but for recovery you need:

• 🔧 root access (for Titanium Backup)
• 🖥️ Computer with installed ADB Tools (for adb restore)

6. Frequent problems with backups copies and their solutions

Even standard backup functions sometimes malfunction. Let's look at typical errors and ways to fix them.

Problem 1: The backup copy is not created

Possible causes and solutions:

• 🔌 No Internet - check Wi-Fi connection (cloud copies do not work via mobile data).
• 🔋 Low space in Google Drive — clear the cloud or buy additional space.
• ⚙️ Disabled backup —check your settings Settings → Google → Backup.
• 📱 Outdated version of Android - update the system (on versions below 8.0 backups are unstable).

Problem 2: Application data is not restored

Many apps (especially games) do not support cloud backup. Solutions:

• 🎮 Use built-in saving functions (for example, linking to an account in games).
• 📱 Create a local backup via Titanium Backup (requires root).
• ☁️ Check if it supports application Android Backup Service (the list can be found on the developer's website).

Problem 3: The backup files are damaged

If the "File is damaged" error occurs during recovery, try:

1. Download the copy again (for cloud backups).
2. Check the integrity of the file via 7-Zip or WinRAR (local copies).
3. Create a new backup copy from scratch.

7. Alternative backup methods

If standard methods do not suit you, consider third-party solutions. They offer more flexibility, but require additional steps.

1. Titanium Backup (requires root)

Allows you to create complete copies of applications and their data, including system settings. The downside is that it is difficult for beginners and requires superuser rights.

2. Swift Backup (without root, but with limitations)

Works on most devices without root, but does not save all data (for example, it cannot backup some system applications).

3. Cloud services (Dropbox, Yandex Disk, Mega)

You can manually upload important files (photos, documents) to these services. Minus - there is no automation for applications and settings.

4. Computer utilities (Samsung Smart Switch for PC, dr.fone)

PC apps allow you to create complete images of your phone and restore them to another device. Suitable for deep backup before sale or repair.

Backup method	Requires root	Automation	Application support	Where stored
Google Backup	❌ No	✅ Yes	⚠️ Partially	Google Drive
Samsung Smart Switch	❌ No	✅ Yes	✅ Full	Local/OneDrive
Titanium Backup	✅ Yes	❌ No (manual launch)	✅ Full	Local/cloud
ADB Backup	❌ No	❌ No	✅ Full (except for some system data)	On a computer
Swift Backup	❌ No (but with restrictions)	✅ Yes	⚠️ Partially	Local/cloud

Is it possible to restore a backup to a phone of another brand?

Technically yes, but with reservations:

- Google cloud copies (contacts, calendar, some settings) will be restored on any Android.

- Local backups (Smart Switch, Mi Mover) usually work only on devices from the same manufacturer.

- Application data will be restored only if the new device supports the same architecture (ARM/x86) and version of Android.

8. How to protect backups from loss

A backup is useless if it cannot be restored. Follow these rules to avoid losing data:

1. Store copies in multiple places

Don't rely only on the cloud or only on local storage. Optimal scheme:

• ☁️ Cloud (Google Drive or manufacturer) - for automatic copies.
• 💾 Local backup on a memory card or computer - for critical data.
• 🔐 Encrypted archive (for example, via 7-Zip) - for confidential information.

2. Check the integrity of the copies

Periodically test restoring from a backup, especially before important events (selling a phone, updating firmware). To do this:

1. Create a test copy.
2. Restore it on another device or after a reset.
3. Make sure that all data is in place.

3. Encrypt sensitive data

If your backup stores passwords, financial information or personal photos, encrypt the file. Suitable for this:

• 🔐 VeraCrypt (for PC)
• 📱 Cryptomator (for mobile devices)

4. Update backups regularly

Set a reminder (for example, once a month) to create a fresh copy. Automatic solutions (Google Drive, Smart Switch) simplify the task, but do not cover all cases.

⚠️ Attention: Some manufacturers (for example, Samsung) may change the location of backup folders in new versions of shells (One UI, MIUI, EMUI). Before deleting files, check their contents or use official utilities to manage copies.

🔍 Frequently asked questions

Is it possible to restore a backup after resetting the phone to factory settings?

Yes, but only if a copy was created before reset. After a hard reset, all local backups (except those on the memory card) are deleted. Cloud copies (Google Drive, Samsung Cloud) will remain available. To restore your data, when you first set up your phone, select the "Restore from backup" option and sign in to your account.

Why does a WhatsApp backup weigh so much?

WhatsApp by default includes in the backup not only text messages, but also all media files (photos, videos, voice messages) that you have ever received or sent. To reduce the size:

1. Open Settings → Storage → Storage management.
2. Delete unnecessary media files (they will remain in chats, but will not be included in the backup).
3. Disable automatic media downloading in the chat settings.

How to find out when the last backup was made?

For Google cloud copies:

1. Go to Settings → Google → Backup.
2. Click on the name of your device - the date of the last backup will be displayed.

For local copies (for example, Smart Switch), open the folder with the backup and look at the date the files were modified (sort by date).

Can I restore a backup to a phone with a different version of Android?

Depends on the type of copy:

• ☁️ Google cloud copies —usually restored, but some settings may not apply if the Android version is very different (for example, from 9 to 13).
• 📱 Local backups (Smart Switch, adb)—may not work if the system architecture has changed (for example, from Android 10 by 12).
• 🎮 Application data — are restored only if the application supports the current OS version.

Before restoring, check compatibility on the forums (for example, 4PDA) or in the manufacturer's support.

What to do if the backup is not restored due to the "Insufficient space" error?

This error occurs if the phone does not have enough memory to unpack the backup. Solutions:

• 🗑️ Free up space (delete unnecessary files, applications, cache).
• 📁 Transfer the backup to a memory card (if your phone supports it).
• 🖥️ Restore the copy via your computer (for example, using Samsung Smart Switch for PC).
• ⚙️ Break the backup into parts (if you use Titanium Backup or adb).

For cloud copies, make sure that there is enough space on the phone for temporary files (they are created during recovery and then are deleted).
