Losing important data on a smartphone is always a nasty surprise, especially when it comes to contacts, messages or system settings. Xiaomi and Redmi device owners have a powerful built-in backup tool that is often ignored until critically needed. Local backup allows you to keep a full cast of the system, including applications and their data, without resorting to cloud services.
The recovery process can be confusing because of the features of the MIUI shell and the new HyperOS, which periodically change the location of the menu. However, with the correct algorithm of actions, you can return all data in minutes. It is important to understand that the local backup is stored directly in the device memory, which requires a backup file.
In this article, we will take a look at all the recovery steps, from finding hidden files to eliminating common errors. You will learn how to properly prepare your gadget so that the process goes without crashes and loss of information. The local backup is encrypted by default and is tied to your current Mi Account, which is a key security point.
Preparation of the device and verification of the availability of a backup copy
Before any manipulations are initiated, you need to make sure that the backup file is real and not corrupted.The standard backup storage path in the Android file system is usually hidden from the user's eyes to prevent accidental deletion. To access this data, you will need a file manager with system folder viewing rights or a standard conductor with hidden files displayed enabled.
Find the MIUI/backup/AllBackup folder in the internal storage. This is where the backup date folders are located. If you plan to recover data after a reset or on a new device, this file must be moved to the specified directory before it is located. Without the file in the correct folder, the system simply will not see the possibility of recovery.
⚠️ Warning: Make sure that the battery is at least 50%, as the process of unpacking and installing data can be energy intensive.
Check the disk space. To deploy the backup successfully, the amount of free memory must be about twice the size of the backup file itself, which is required by the system to temporarily store the decompressed data before it is finally integrated.
☑️ Pre-reconstruction checks
Recovery through the standard settings menu
The safest and most correct way to return data is to use a regular shell interface, which ensures that all system permissions are respected and the data is in the right memory areas. Go to Settings → About Phone → Backup and Restore (the path may vary slightly depending on the version of MIUI).
In the window that opens, select the Mobile Device tab. If the backup file is found and compatible with the current firmware version, you will see a list of available restore points with the date and time of creation. Click on the desired file to go to select data categories.
The system will suggest you to choose which to restore: contacts, messages, call log, system settings or installed applications. Be careful when choosing applications, since it can take a long time to recover their data. Once the selection is confirmed, a process will begin, the progress of which will be displayed on the screen.
While it is not recommended to switch between apps or lock the screen during the process, while modern versions of Android are able to pause background tasks, it is better not to risk the stability of the procedure.
Solving Password and Encryption Problems
A common problem with local copy recovery is asking for a password, and if backup protection is installed, the system will require you to enter it before unpacking, an Android security mechanism that prevents unauthorized access to your personal data even when you have physical access to the files.
If you forget your password, you can't recover it with standard tools, you can't encrypt it with reliable algorithms, you can't get around it without a key, but if the backup was created without a password, and the system requires it, it could indicate a conflict of Mi Account accounts.
- 🔑 Make sure that the phone settings have the same Mi Account that was used to create the copy.
- 🔄 Try resetting your Mi Account password through the official website if your phone is lost.
- 📱 Check if there was a system update that could have changed the storage encryption algorithms.
⚠️ Warning: multiple failed attempts to enter the password may temporarily lock the backup restoration feature.
In some cases, creating a new backup with a new password helps, after which the old data can be tried to integrate manually through the file manager, although this applies only to media files and documents, but not to application settings.
Comparison of recovery methods: locally or cloud
Users often wonder which way to back up is more reliable: Local copying gives full control over data and does not depend on Internet speed, but requires the physical preservation of the file. Mi Cloud cloud storage is convenient for syncing contacts and photos, but has limitations on the amount of free space.
| Parameter | Local backup | Mi Cloud | Computer (Mi PC Suite) |
|---|---|---|---|
| Speed of operation | High (depends on memory) | Depends on the Internet. | High (USB 3.0) |
| Data volume | Limited to phone memory | 5GB free of charge | Limited to a PC drive |
| Type of data | Complete copy of the system | Contacts, photos, notes | Media and files |
| Security | Encryption on the device | Account protection | Physical access |
For maximum reliability, combine these methods: Keep critical documents in the cloud, and save full system images locally or on a computer. This 3-2-1 approach (three copies, two media, one elsewhere) is considered the gold standard in IT.
Why can’t cloud backups see local?
Data recovery after reset to factory settings
The most critical situation is when the phone is reset to factory settings, in which case all user data is deleted, and the only salvation is a pre-created backup file. If the file is left on the memory card or transferred to the computer, the process begins with its return to the phone memory.
Copy the backup date folder to the MIUI/backup/AllBackup directory, and then the action algorithm repeats the standard procedure through the settings menu, and the system scans the folder, finds the file, and suggests recovery.
It is important to note that the post-reset firmware version must be the same or newer than the version on which the backup was created. Attempting to restore data from the old version of MIUI to the new version is often successful, but backward compatibility (from new to old) is usually blocked by the system to avoid conflicts.
💡
If after recovery, the application icons disappeared, but the applications themselves work, try restarting the launcher or resetting it in the Applications menu.
Once the process is complete, check the integrity of the data, open the gallery, phone book, and messengers, and if any data is missing, it may not have been selected when you created the original copy or may be in secure areas that require re-authorization.
Frequent errors and ways to fix them
The recovery process is not always smooth. Users may encounter a message "File is corrupt" or "No space" even if visually all conditions are met. Often the problem lies in the file system or access rights.
One common mistake is to try to restore a backup made on a device with a different processor architecture or a very different version of Android, in which case the system may refuse to restore applications by saving only contacts and media files.
- 📉 “Not enough space” error: Clear the app cache or delete unnecessary downloads before starting.
- 🚫 Format Not Supported Error: Check if the file has been renamed or moved to the wrong folder.
- 🔒 Access Error: Make sure the file manager is given permission to work with memory.
⚠️ Warning: Do not attempt to edit the contents of files inside the backup folder manually.This will break checksums and restore will become impossible.
If standard methods don’t help, you can try using Safe Mode for Recovery to eliminate the impact of third-party antivirus applications or optimizers that can block the recording of system files.
💡
The success of recovery is 90% dependent on the correct path to the file and the matching versions of the operating system at the time of creation and recovery of the copy.
Use of third-party utilities and ADB
For advanced users, it is possible to work with backups through USB debugging and the ADB utility (Android Debug Bridge), which allows you to forcibly copy the backup folder even in cases where the phone interface does not respond correctly.
Connect your phone to your computer, enable USB debugging in the Developer Menu. With the adb push command, you can upload a backup file to the right directory if the standard file manager can't handle it.
adb push C:\Backup\date_folder /sdcard/MIUI/backup/AllBackup/This method is especially useful when you need to recover data on a device with a broken screen using previously installed drivers and settings. However, for ordinary users, it is recommended to stay within the GUI to avoid the risk of damage to the loader.
There are also third-party apps from Google Play that promise enhanced backup functionality, but using them requires caution, and they may request excessive permissions, which compromises your data privacy.
