Users of the Xiaomi ecosystem often face the need to save important data before they run firmware or switch to a new smartphone. The question of where the backup in Xiaomi is located becomes critical when you need to quickly restore contacts, SMS or application settings. Standard paths in the Android file system can be hidden or changed depending on the version of the MIUI shell.
In this article, we will take a closer look at the structure of data archives, how to create them through embedded tools and cloud services, how to find hidden backup folders, how to transfer them to your computer, and what to do if a standard recovery mechanism fails, and understanding these processes will make you feel more confident whenever you manipulate your device.
Standard ways to store local backup copies
By default, the Android operating system, and in particular the MIUI shell, stores local copies of data in the root directory of internal memory. If you used the built-in tool "Reserve and Restore", your files are likely to lie along the path /MIUI/backup/AllBackup/. This is where archives with the extensions.bak or.ab accumulate.
Inside this folder, you'll find subdirectories with backup dates, which allows you to store multiple versions of backups, but it's worth remembering that when you reset to the factory, the contents of the internal memory are erased, so it's critical to periodically copy the contents of the AllBackup folder to an external drive or to the cloud.
To access hidden system folders, you may need to enable the display of system files in the Explorer. In the standard Explorer application from Xiaomi, you need to click on three dots in the upper corner and select the appropriate option. Without this step, the MIUI folder may not be visible or access to it will be limited.
⚠️ Note: When removing or moving files from the folder /MIUI/backup/AllBackup/ manually through third-party file managers, the system may stop "seeing" backups in the settings menu.
There is also a division into data types: System settings and application lists usually take up less space than multimedia files or messenger data, and heavy archives can weigh several gigabytes, which is important to consider when there is free disk space.
Use of built-in backup tool
The main tool for creating local copies in Xiaomi, Redmi and Poco smartphones is a system utility hidden in the depth of settings. To start the process of creating a backup, you need to go to Settings → About Phone → Reserve and Restore, where the user can choose what data is to be saved.
The utility interface allows you to flexibly configure settings. You can eliminate large files or specific applications to reduce the size of the final archive, which is especially useful if you plan to store copies on cloud services with a limited free rate.
☑️ Checking before creating a backup
It's important to note the difference between backup and account synchronization, because local redundancy creates a full snapshot of the status of the apps and settings you select at launch, and it even includes some data inside games and programs that isn't stored in normal Google sync.
The creation process can take anywhere from 5 to 30 minutes, depending on the amount of data and the speed of the drive, at which time it is better not to use the phone, so as not to damage the integrity of the archive being created, and after completion, the system will suggest setting a password to protect the file.
- 📂 Full backup: Saves applications, system settings, alarms, Wi-Fi passwords and SMS.
- 📸 Multimedia: You can choose to reserve photos and videos separately, although Google Photos are more often used for this.
- 🔒 Security: The ability to set a password to a backup file protects data when you lose your device.
Working with the Mi Cloud cloud service
An alternative to local storage is the Mi Cloud cloud service, which is integrated directly into the shell and allows you to synchronize key data in real time. To activate the function, you need to log into your Mi Account account through the Settings → Mi Account menu.
Unlike a local copy, cloud sync doesn't create a single archive file that can be moved; it stores data in a structured form on the company's servers, which means that when you restore it to a new device, you just need to log in to your account, and the data will "fly" automatically.
Free space is provided to the user, which is usually enough for contacts, notes, voice recordings and photos in compressed quality. Large amounts of data, such as full copies of the system or original high-resolution photos, will require an expansion of the tariff.
What is synchronized automatically?
If you have the option of sync with Mi Cloud enabled, original photos can be deleted from the device after uploading to the cloud to save space. Always check the download status before clearing the phone's memory.
Recovery from the cloud occurs either when you initially set up your phone or force it through the sync menu, which depends on the speed of the Internet connection, and when using mobile traffic, the system can pause the download of large files before connecting to Wi-Fi.
Search and Recovery of Data from the Archive
The procedure for recovering data from local copy requires care. If you reset your phone to factory settings, the first step is to reset the language and Wi-Fi. Then, by going down the Settings path → About Phone → Reservation and Restore → Mobile device, you will see a list of available backups.
Select the date you want and click Restore. The system will ask for a password if it was set when you created the copy. It's important to understand that it can take a long time to restore applications, since the phone will re-download the installation files from Google Play and then unpack your data.
Sometimes users are faced with a situation where the backup file is there, but the system does not see it. This can happen if the file was renamed or moved to the wrong directory, in which case you need to manually place the folder with the date back in /MIUI/backup/AllBackup/.
💡
If recovery is stuck at a certain percentage, try restarting the device and starting the process again, often bypassing temporary file system errors.
For advanced users, it is possible to use ADB (Android Debug Bridge) to force recovery or analysis of backup content. However, standard MIUI means to open the contents of the.bak file without recovery is not possible for security reasons.
Table of comparison of data retention methods
To choose the best way to protect your information, you should compare the options available, each with its advantages and disadvantages depending on your goals: full migration to a new phone or just insurance against data loss.
| Method | Where it's stored | We need the Internet. | Saves Wi-Fi passwords |
|---|---|---|---|
| Local backup | Phone memory | No. | Yes. |
| Mi Cloud | Xiaomi servers | Yes (for download) | Yes. |
| Google One | Google servers | Yes (for download) | Partially. |
| PC Suite / ADB | Computer | No. | Yeah (with root) |
As you can see from the table, local redundancy is the most autonomous method that doesn't require a connection to the network, but it's the least reliable in the event of physical loss or breakdown of the smartphone itself, and combining the methods yields the best result.
Using third-party cloud storage, such as Google Drive, is also possible, but the functionality there is often limited to basic settings and a list of applications, without saving their internal state (logins, progress in games).
Solving common problems and errors
When working with backups, users may encounter an error such as “failed to create a backup copy” or “Recovery interrupted.” Most often, the reason lies in a lack of free space or damage to the file system. Before starting the procedure, always check for at least twice the amount of free space relative to the data size.
Another common problem is incompatibility of MIUI versions. Trying to restore a backup made on a newer firmware version to a device with an older version can lead to errors or cyclical reboots. Always try to maintain current software or backups before major updates.
If the recovery process is suspended during the unpacking phase of the application, this may indicate damage to the archive itself, in which case only creating a new backup helps if the original data is still stored on the device.
To diagnose problems, you can use Safe Start mode to exclude the influence of third-party launchers or antiviruses that block access to backup system files.
⚠️ Warning: Never interrupt the recovery process by forced reboot, which can result in a database of contacts or system settings being compromised, requiring a complete reset.
