Where Android stores copies of files: a complete guide to backup folders and cloud backups

Have you accidentally deleted an important file on your smartphone and are now trying to find its backup? Or just want to understand how Android automatically saves duplicates your data? Unlike Windows or macOS, where backups are often created manually, the mobile OS works differently: copies of files are scattered across system folders, cloud services, and even hidden memory sections. The problem is that most users do not know where exactly to look for this backup data - but in vain.

In this article we will analyze all possible places for storing copies on Android: from standard folders /data/backup to cloud services like Google Drive i Samsung Cloud. You will learn how to find backups contacts, photos, messages and even application data, as well as what to do if there are no backups. Important: some methods require root access or special utilities - we will note such cases separately.

Spoiler: if you have never set up a backup manually, the chances of recovering deleted files depend on the Android version, smartphone manufacturer, and even processor model. But don’t rush to panic - in 80% of cases, copies still exist, you just need to look for them correctly.

1. Android system folders: where local copies are stored

Android creates backup copies of some data automatically, but they are rarely accessible through the standard file manager. Most of these copies are hidden in system partitions, which cannot be accessed without root or ADB. Here are the key locations:

• 📁 /data/data/<package_name>/databases — Application databases are stored here (for example, message history in WhatsApp or Telegram). Copies are created when the application is updated.
• 🔄 /data/backup —standard folder for backups made by the system via adb backup. Usually empty if you did not run the command manually.
• 📱 /sdcard/Android/data/<package_name>/files — some applications (for example, Viber) save backup copies of media files here.
• 🔒 /data/system/backup — system backups, accessible only with superuser rights. Contains copies of Wi-Fi settings, APN and other parameters.

⚠️ Attention: The folder /data on most smartphones is encrypted. Even if you receive root, its contents may be unreadable without the original device password. On Samsung s Knox or Pixel s Titan M access to this data is often blocked at the hardware level.

To check the availability of local copies without root, connect your smartphone to the PC and use the command:

adb shell ls /data/backup

If the folder exists but is empty, then automatic backups are disabled. On some firmware (for example MIUI or ColorOS) copies can be stored in /MIUI/backup or /Oppo/backup.

2. Cloud services: automatic backups from Google and manufacturers

Most modern Android smartphones synchronize data with clouds by default. Here are the services that can store copies of your files:

Service	Data types	How to check	Restrictions
Google Drive	Contacts, calendars, photos (if enabled Google Photos), data from some applications	Open drive.google.com → "Storage" → "Backups"	Application backups are created only when the system is reinstalled. Photos are stored in compressed quality (unless paid for) days) Google One)
Google Photos	Photos, videos, screenshots	Application Google Photos → "Library" → "Trash" (stores deleted files for 60 days)	Files older than 60 days are deleted permanently. Original quality takes up space in the cloud
Samsung Cloud	Contacts, messages, notes, data Samsung Apps (for example, Samsung Notes)	Settings → Accounts and archiving → Samsung Cloud	Available only on devices SamsungFree - 15 GB, then paid expansion
Mi Cloud (Xiaomi)	Contacts, SMS, photos, call records, data Mi Apps	Settings → Mi Account → Mi Cloud	On some models, backups are created only with manual activation

🔍 How to find hidden copies in Google Drive:

1. Open Google Drive in the browser.
2. In the search bar, enter type:backup —this will show all backups associated with your account.
3. To restore data from a backup, you will have to reset your smartphone to factory settings and log into the same account Google.

⚠️ Attention: If you deleted a file from Google Photos or Google Drive, check the "Trash" folder in these services. In Google Photos files are stored there for 60 days, in Drive - 30 days. After this, recovery is impossible.

3. Application backups: WhatsApp, Telegram and other instant messengers

Many popular applications create their own backups that do not depend on Android system mechanisms. Let's look at the most important ones:

• 💬 WhatsApp: Copies of chats are stored in /sdcard/WhatsApp/Databases. The files look like msgstore.db.crypt14 (where crypt14 is the encryption version). To restore, you need to reinstall the application and confirm your phone number.
• 📤 Telegram: Cloud chats are synchronized automatically, but local media files can be found in /sdcard/Telegram/Telegram Images or /sdcard/Telegram/Telegram Documents.
• 📧 Gmail: Emails and attachments are stored only in the cloud. Local copies (if offline mode is enabled) are in /data/data/com.google.android.gm/databases.
• 🎵 Spotify/Yandex Music: Cached tracks are in /sdcard/Android/data/com.spotify.music/files or /sdcard/Android/data/ru.yandex.music/files. These are not backup copies, but deleted tracks can be restored from here.

🔧 How to restore WhatsApp chats from a local copy:

1. Uninstall the application and install it again.
2. When prompted to restore, select the option "Restore from local copy."
3. If the copy is damaged, rename the file msgstore.db.crypt14 v msgstore.db.crypt14.current and try again.

⚠️ Attention: In WhatsApp local backups are overwritten daily at 2:00 local time. If you deleted a message after the last backup, you will not be able to restore it. For Telegram this is irrelevant - all messages are stored in the cloud.

View folder /sdcard/WhatsApp/Databases

Check the date of the last backup in WhatsApp (Settings → Chat → Backup)

Make sure that media synchronization is enabled in Telegram Settings → Data and memorySettings → Data and memory)

Download a copy of chats Viber via Settings → Account → Backup-->

4. Hidden memory sections: recovery and EFS

On Android devices there are special memory sections that are not visible to the user, but contain critical data. Two of them can store copies. files:

• 🛠️ Recovery: This partition is used to restore the system. Some custom recovery (for example, TWRP) allow you to create full backups (nandroid backup) of all partitions, including /data and /system. c /sdcard/TWRP/BACKUPS.
• 📡 EFS (Encrypted File System): Contains unique device data, such as IMEI, serial numbers and calibration files. Copies of this section are sometimes created during firmware through Odin (for Samsung) or Fastboot. extension .efs or .qcn.

🔍 How to check for backups in TWRP:

1. Boot into recovery (usually Power + Volume Up).
2. Select Backup → Select Storage → Internal Storage.
3. If there are saved backups, they will appear in the list. You can restore or copy to PC.

⚠️ Attention: Partition EFS critical for the operation of the smartphone. Damage to it can lead to network loss (IMEI NULL) or complete inoperability of the device. Do not edit files in this section without a clear understanding of the consequences.

On devices with a chip Qualcomm (most Xiaomi, OnePlus, Sony) copies of the section EFS can be created via command adb shell su -c "dd if=/dev/block/bootdevice/by-name/modemst1 of=/sdcard/modemst1.img". For Samsung Exynos or Mediatek the path to the section will be different.

5. How to restore files if there are no copies

If you did not find backup copies in any of the listed places, there are two options left: using data recovery apps or contacting specialists. Let's consider both methods.

🔧 Recovery apps

There are several utilities that scan the smartphone's memory for deleted files:

• 🖥️ DiskDigger —works without root, but only recovers photos and videos.
• 📱 EaseUS MobiSaver —supports recovery of contacts, messages and documents, but requires root for deep scanning.
• 💻 Recuva (for PC)—suitable if you connect a memory card microSD to a computer.

📌 Instructions for recovery via DiskDigger:

1. Install DiskDigger from Google Play.
2. Select the file type to search (for example, "Photos and Videos").
3. Start scanning. If deleted files are found, mark them and click "Recover".
4. Save the recovered data to a memory card or to the cloud.

🔧 Professional help

If files are critical (for example, business documents or single photos), and software recovery did not help, contact data recovery laboratory. The cost of the service depends on the complexity:

• 💰 Recovery from a memory card: from 1,500 to 5,000 rubles.
• 💰 Recovery from internal memory (without physical damage): from 5,000 to 15,000 rubles.
• 💰 Working with damaged chips memory: from 20,000 rubles (soldering equipment required).

⚠️ Attention: The more actively you use your smartphone after deleting files, the lower the chances of recovering them. New data overwrites old memory sectors. If the files are valuable, immediately turn off the device and do not turn it on until recovery begins.

Is it possible to restore files after resetting to factory settings?

Yes, but with big reservations. During a "soft" reset (via Settings), the data is logically deleted and can be restored by apps. With a “hard” reset (via Recovery) or flashing, the chances are minimal - professional equipment is required to read the memory chip directly.

6. How to set up automatic backup for the future

To avoid searching for copies of files in emergency situations, set up automatic backup in advance. Here's what you can do:

📱 Android Settings

1. Enable Google backup:

   Settings → Google → Backup → Data backup

   Activate the switch here and select an account to save.

2. Set up synchronization of contacts and calendars:

   Settings → Accounts → Google → Account synchronization

3. For Samsung, Xiaomi and other brands, enable branded cloud services (see. table in section 2).

🖥️ Third-party solutions

• 🔄 Swift Backup (requires root) - creates copies of applications and their data.
• ☁️ Titanium Backup - classic utility for full backups (also required root access).
• 📁 FolderSync — synchronizes selected folders with clouds (Dropbox, OneDrive, Yandex Disk).

📌 Setting recommendations:

• Create local copies of important files on a memory card once a week.
• Use two cloud services (for example, Google Drive + Mega) to duplicate data.
• Before updating firmware, make a full backup via TWRP or ADB.

⚠️ Attention: On Android 12 and later, Google has limited app access to files of other apps. This means that many backup utilities (for example, Titanium Backup) stopped working without root. If you need complete copies of the data, consider obtaining superuser rights or use alternatives like Swift Backup with module Shizuku.

FAQ: Frequently asked questions about backups on Android

Is it possible to recover deleted SMS if there is no backup?

Without a backup, the chances are minimal. Try apps like EaseUS MobiSaver (requires root) or contact the service center. On some firmware (for example MIUI) SMS are stored in the database /data/data/com.android.providers.telephony/databases/mmssms.db - you can try to extract it via ADB.

Where are copies of photos deleted from the gallery stored?

Check the folder first /sdcard/DCIM/.thumbnails - sometimes miniatures remain there. If the photos were synchronized with Google Photos, look in the service trash (stores files for 60 days). Local copies may remain in the application cache (for example, /sdcard/Android/data/com.google.android.apps.photos/cache).

How to transfer backups from one Android to another?

Methods depend on the type of data:

• 📱 Contacts/calendars: Synchronize through your account Google.
• 💬 Messages: Use backup SMS Backup & Restore (saves in XML).
• 📷 Photo/video: Copy the folder DCIM to a new smartphone or synchronize via Google Photos.
• 🎮 Game data: If the game supports Google Play Games Cloud Save, sign in to the same account. For the rest, use Helium (requires a PC).

Why doesn't Google Drive show backups of my phone?

Possible reasons:

• The backup was created under another account Google.
• Backup is disabled on the device (Settings → Google → Backup).
• More than 57 days have passed since the last backup - Google automatically deletes old copies.
• You are using a work account (Google Workspace), where the administrator has disabled backup.

Check all linked accounts on the page myaccount.google.com → "Data and personalization" → "Backups."

Is it possible recover data from a broken screen?

Yes, if the smartphone turns on and responds to touches. Connect it to the PC via USB-OTG with a mouse or use ADB to control. If the screen does not work at all, you will need to:

1. Connect the device to the PC and try to extract the data. via adb pull /sdcard.
2. Use USB-JIG to download to Download Mode (for Samsung) and flash custom recovery.
3. Contact a service center to replace the screen or directly read the memory.
