Backups folder on Android: what is this directory, can it be deleted and how to clean it without consequences

Have you ever noticed a folder on your smartphone with the name Backups (or /sdcard/Backups, /storage/emulated/0/Backups) and wondered what she was like? This directory appears on most devices running Android —from budget Xiaomi Redmi to flagship Samsung Galaxy —but its contents are rarely explained in official documentation. Gigabytes of data can be stored inside, which takes up precious space, but deleting them “blindly” is dangerous: some files are critical for restoring the operation of applications or the system.

In this article we will analyze in detail:

• 🔍 What is a folder Backups and what types of backups it stores (from system to user).
• 📱 Which applications and services create backups in this directory (including hidden functions Google and smartphone manufacturers).
• ⚠️ Can it be deleted folder Backups without risk to data - and what happens if you do it incorrectly.
• 🧹 How to safely clear unnecessary backups without affecting critical files.

We will pay special attention to hidden backups that are created automatically when updating the firmware or resetting settings - deleting them can lead to inability of some functions after a system restore.

What is the Backups folder on Android and why do you need it?

The folder Backups is a standard directory in the file system Android, intended for storage data backups. It can be located in different places depending on the OS version and manufacturer:

• 📁 /sdcard/Backups/ — on older versions of Android (up to 10).
• 📁 /storage/emulated/0/Backups/ — on modern devices (Android 11+).
• 📁 /Android/data/[package_name]/files/Backups/ — backup copies of specific applications.

Unlike cloud backups (for example, Google Drive or Mi Cloud), files in this folder are stored local and take up space in the device’s internal memory. Their main purpose is fast data recovery without the need to download them from the Internet. For example:

• 🔄 Recovery after reset: If you did a factory reset (hard reset), some applications may automatically restore their data from this folder.
• 📲 Transfer to a new device: Some brands (for example Samsung or Huawei) use local backups to migrate data when replacing a smartphone.
• 🛠️ Rolling back updates: System backups allow you to return the previous firmware version if a new one the update is unstable.

However, not all files in this folder are equally useful. Often they accumulate here outdated or duplicate copies, which are no longer relevant, but continue to take up space. For example, backups of games that you deleted long ago, or backup copies of applications that have switched to cloud storage.

⚠️ Attention: On some devices (especially with custom firmware), the folder Backups may contain critical files for restoring IMEI or communication module. Deleting them will lead to loss of the network!

What data is stored in the Backups folder: a complete analysis of the contents

The contents of the folder Backups varies depending on the smartphone model, version Android and installed applications. Below is a table with the most common file types and their purpose:

File/folder type	Example path	Purpose	Can I delete
System backups	/Backups/backup_*.ab	Backups of system settings created before a firmware update or reset.	❌ No (risk of loss of functionality)
Application backups	/Backups/app_*/	Data of specific apps (for example, saving games, settings messengers).	⚠️ Partially (only if the application is deleted)
Logs and temporary files	/Backups/logs/	Logs of backup operations (usually not needed by the user).	✅ Yes
SMS/MMS backups	/Backups/sms_*.xml	Exported messages (created by applications like SMS Backup & Restore).	✅ Yes (if not needed)
IMEI recovery files	/Backups/nvram/ or /Backups/modem/	Critical data for the operation of the mobile network (on some devices).	❌ No (risk of loss of connection)

Deserving special attention hidden system backups, which are created:

• 🔧 When updating the firmware via OTA (by air).
• 🔄 When resetting the settings (Factory Reset).
• 📱 When using proprietary backup utilities (for example, Samsung Smart Switch or Xiaomi Cloud).

For example, on devices Samsung in the folder /Backups/ files with the extension .csc can be stored - these are backups of regional settings, without which, after resetting, the smartphone may “forget” the interface language or parameters networks.

What are *.ab files in the Backups folder?

These are binary archives created by the utility adb backup They contain encrypted application and settings data. You can delete them, but it will be impossible to restore them later without special tools.

What applications create backups in this folder (and how to disable it)

Many apps automatically save backups to the folder Backupswithout notifying the user Here are the most common culprits:

• 🎮 Games: Genshin Impact, PUBG Mobile, Clash of Clans and others save progress here if the cloud is disabled. backup.
• 💬 Messengers: WhatsApp, Telegram (if local backup of chats is enabled).
• 📱 Branded utilities: Samsung Smart Switch, Huawei Backup, Xiaomi Cloud.
• 🔧 System tools: Google One, Titanium Backup (for rooted devices).

To stop automatic creation of backups, check the settings:

1. For games: open Game Settings → Account → Backup and disable local saving.
2. For messengers: in WhatsApp go to Settings → Chat → Backup and select only Google Drive.
3. For system utilities: in Samsung Smart Switch disable the option Automatic backup.

On devices with Android 12+ some backups have been transferred to secure storage (/Android/obb/ or /Android/data/), but some applications still use the old folder Backups for compatibility.

Is it possible to delete the Backups folder: risks and consequences

The answer to this question depends on the contents of the folder i your model. devices. Here are the key points:

• ✅ You can delete:
  • Backups of deleted applications (for example, games that you uninstalled a long time ago).
  • Logs and temporary files (folders logs, temp).
  • Duplicate copies (for example, if you have a cloud backup the same data).
• ❌ You cannot delete:
  • Files with extensions .ab, .csc, .nvram (critical for the system).
  • Backups created before updating the firmware (if you plan to rollback).
  • Folders with names modem, radio, imei.

For example, if you delete files from a folder /Backups/nvram/ on a smartphone MediaTek, you risk losing it IMEI, which will lead to a lack of mobile network. On devices Qualcomm the files in /Backups/efs/.

⚠️ Attention: On some devices Xiaomi and Realme folder Backups contains files for recovery DRM keys (for example, for Widevine L1). Deleting them will lead to loss of support Full HD in streaming services!

If you are not sure which files can be deleted, use verified method:

1. Copy the entire folder Backups to a computer or cloud.
2. Delete only those files whose names you recognize as deleted applications (for example, com.game.removed_2023.backup).
3. Reboot the device and check operation.

How to safely empty the Backups folder: step-by-step guide

If you decide to free up space, follow this algorithm:

Step 1: Checking the contents

Use a file manager (for example, Solid Explorer or FX File Explorer) to analyze the folder:

1. Open /storage/emulated/0/Backups/.
2. Sort the files by date of modification —old copies (for example, 2020–2022) are most likely not relevant.
3. Check the size of the folders: if app_* occupies several gigabytes, and the application has been deleted for a long time - you can clean it.

Step 2: Removing unnecessary files

You can safely delete:

• 🗑️ Folders with the names of deleted applications (for example, com.nianticlabs.pokemongoif the game has been around for a long time uninstalled).
• 📄 Files with extensions .log, .tmp, .old.
• 📂 Folders sms, call_logsif you are not restoring old messages.

To delete:

1. Select unnecessary ones files.
2. Click “Delete” (or move to the trash).
3. Empty the trash to free up space.

Step 3: Check after cleaning

After deleting:

• Reboot the device.
• Check the operation of the mobile network (calls, Internet).
• Make sure that critical applications (banks, instant messengers) are working stably.

If problems arise (for example, the network is lost), restore deleted files from a backup copy (step 1).

How to transfer backups to the cloud and free up space

If the folder Backups takes up too much places, but you don’t want to lose data, transfer them to cloud storage:

Method 1: Google Drive

For backup:

1. Open Settings → Google → Backup.
2. Enable the option Upload to Google Drive.
3. Select what data to save (applications, SMS, settings).

After synchronization, local backups can be deleted.

Method 2: Proprietary cloud

Manufacturers offer their solutions:

• 📱 Samsung Cloud: Settings → Accounts and backup → Samsung Cloud.
• 📱 Xiaomi Cloud: Settings → Mi Account → Mi Cloud → Backup.
• 📱 Huawei Cloud: Settings → Huawei ID → Cloud → Backup.

Method 3: Manual copy to PC

If the cloud is not suitable:

1. Connect your smartphone to the computer via USB (in file transfer mode).
2. Copy the folder Backups to your hard drive.
3. Delete it from the phone, leaving only critical files (see section above).

You can use Syncthing or FolderSync —these applications synchronize folders between devices on a schedule.

What to do if problems arise after cleaning Backups

If, after deleting files from the folder Backups the smartphone begins to work incorrectly, do the following steps:

Problem 1: Lost mobile network

Symptoms: no signal, SIM card not detected, error IMEI Null.

Solution:

1. Check whether you deleted files from folders nvram, modem or efs.
2. If yes, restore them from a backup copy (if there is one).
3. If not, try manually re-registering the network: enter in the dialer ##4636##, select Information about the phone and press Turn off the radio, then turn it on again.

Problem 2: Some applications do not work

Symptoms: applications crash, do not save settings or require restarting authorization.

Solution:

• Reinstall the problematic applications.
• Check whether there are files in the folder Backups with the name of the application package (for example, com.whatsapp). them.
• Clear the application cache in Settings → Applications → [Name] → Storage → Clear cache.

Problem 3: The system asks to restore data after a reset

Symptoms: after Factory Reset the smartphone offers to restore data, but the process ends with an error.

1. Skip recovery and set up the device as new.
2. Download the necessary data from the cloud (Google Drive or the manufacturer's proprietary cloud).
3. If critical data was only in a local backup, try restoring it via Titanium Backup (required root access).

⚠️ Attention: On devices with Android 13+ Some system backups are stored in a protected section /data/system/backups/, which is inaccessible without root. Do not try to access it through standard file managers!

FAQ: Frequently asked questions about Backups folder on Android

❓ Why does the Backups folder take up so much space (10+ GB)?

This happens due to:

• 🎮 Game saves (for example, Genshin Impact or Call of Duty Mobile can weigh 4–5 GB).
• 📸 Backup copies of photos/videos (if local backup in the gallery is enabled).
• 📱 System backups created before several firmware updates (they accumulate).

Solution: Analyze the contents of the folder and delete old or duplicate copies.

❓ Is it possible to move the Backups folder to an SD card?

Technically yes, but:

• ✅ Works only for user backups (for example, copies of SMS or games).
• ❌ System backups (for example, to restore after a reset) must remain in the internal memory.

For transfer:

1. Copy the desired folders to the SD card.
2. Create a symbolic link (required root or Termux):
   

   ln -s /storage/extSdCard/Backups /storage/emulated/0/Backups

❓ Why does the Backups folder appear again after deletion?

This is normal system behavior. The folder is restored because:

• 🔄 Android automatically recreates standard directories when rebooting.
• 📱 Applications (for example Google One or games) create backups again.
• 🔧 System services are preparing for next update.

Solution: disable automatic backup in application settings or use Tasker to block folder creation (advanced users).

❓ How to restore data from the Backups folder?

The method depends on the type files:

• 📄 Files .ab: use adb restore in the command line:
  

  adb restore /path/to/file.ab

• 🎮 Game saves: copy the folder with backup in /Android/obb/[package_name]/.
• 💬 SMS/MMS: import via SMS Backup & Restore.

For system backups, you may need custom recovery (for example, TWRP).

❓ Is it dangerous to delete the Backups folder on a rooted device?

On rooted smartphones, the risks are higher because:

• ⚠️ You can delete files that are critical for Magisk or Xposed.
• ⚠️ Some modules (for example, ViPER4Android) store settings c Backups.

Recommendation: before cleaning, make a full backup via TWRP or Titanium Backup.
