Xiaomi smartphone owners often face the need to transfer important data to a new device or secure it before flashing. MIUI shell (HyperOS) offers powerful backup tools, but they are not always obvious to the beginner. Simply reinstalling an app from Play Market won't bring back your progress in gaming, correspondence or setting up banking customers.
To save the data application on Xiaomi, you need to use built-in system utilities or third-party solutions. In this article, we will discuss all available methods, from cloud storage to local backup on the Internet. SD-A card so you can be sure of the security of your digital life.
Use of built-in MIUI backup
The most reliable way that doesn’t require an internet connection is local backup. MIUI-based Android has a hidden but functional mechanism for creating full copies of apps along with their cache and databases, which is ideal if you’re planning to reset or flash your phone.
To activate this feature, go to Settings → About Phone → Backup and Restore. You will need to enter the unlock password to confirm the operation. In the menu that opens, select “Mobile Device” and tick the required programs.
It is important to understand that by default, the system may not save data from some system applications without root rights, but for most user ulits, this method works flawlessly. Once you create a copy, the files are stored in the hidden folder MIUI/backup/AllBackup in internal memory.
💡
Copy the AllBackup folder to your computer or cloud drive immediately after you create a backup so you don’t lose data in the event of a physical smartphone breakdown.
Remember, the local backup takes up space on the internal drive, and if you're making a full copy of the system, make sure you have at least 10-15 GB of space, a critical parameter that will cause an error in the archiving process.
Sync with Mi Cloud and Google Account
Cloud technology automates data storage, and Xiaomi’s Mi Cloud ecosystem is deeply integrated, and it can save not only contacts and photos, but also the list of installed applications and their data, if the developer has the ability to do so.
To set up, go to Settings → Mi Account → Mi Cloud. Here you need to activate sync for the desired categories. Google Drive, in turn, saves the folder structure and some application settings, but often requires additional confirmation when you restore to a new device.
⚠️ Warning: Free space in Mi Cloud is limited to 5 GB. If you plan to store heavy archives with game or instant messenger data there, consider expanding storage or using Google One.
The main advantage of the cloud is automation. You don't have to remember to make copies manually, but the speed of recovery depends on the speed of your Internet connection. With a lot of data, the process can take several hours.
Data transfer with the Mi Mover application
If you want to upgrade to a new Xiaomi smartphone, the best solution is the Mi Mover utility, which is pre-installed on all current models and allows you to transfer data over Wi-Fi Direct without using the Internet, which is the fastest way to clone the system.
The process starts with running the app on both devices. On the old phone, select the role "Sender" and on the new one, "Receiver." Scanning. QR-The code will instantly create a secure communication channel. You can choose to transfer only applications or complete data with them.
The uniqueness of Mi Mover is the ability to transfer even system settings and the location of icons on the desktop. the application automatically recognizes the compatibility of Android versions and adapts the transmitted packages.
☑️ Algorithms for Mi Mover
It is worth noting that some banking applications and secure corporate clients may not be fully portable for security reasons, and in such cases, re-authorization will be required, but the basic data inside them is usually stored.
Comparison of data retention methods
The choice of the specific method depends on your goals: whether you need a full clone of the system or just save contacts and photos. Below is a table that will help determine the best option for your situation.
| Method | Speed of operation | We need the Internet. | Stores application data |
|---|---|---|---|
| Local backup | Tall. | No. | Yeah (almost all) |
| Mi Cloud | Medium | Yes. | Partially. |
| Mi Mover | Very high. | No. | Yes. |
| Google Drive | Low. | Yes. | Minimum. |
As you can see from the chart, local copying and Mi Mover both benefit in speed and completeness of stored information, and cloud services are better suited for background insurance against device loss than for the rapid transfer of heavy data.
When using cloud methods, it is important to consider carrier rates if you are not in a Wi-Fi zone. Downloading a few gigabytes of data can significantly reduce your monthly traffic.
Working with cache and specific data
Not all application data is the same. Cache is temporary files that speed up programs, but saving them is not always critical. However, in games with heavy graphic content (such as PUBG or Genshin Impact), cache can weigh tens of gigabytes.
When you remove an application as a standard, the cache is often deleted with it, so to save an application with this type of data, you better use Mi Mover or a local backup with the box "Other System Data" to avoid re-loading huge resource packets.
Where are the game cache files stored?
For instant messengers like WhatsApp or Telegram, there are their own backup mechanisms. Telegram stores all the history in the cloud, so just log in to your account. WhatsApp requires you to configure a local or Google backup in its internal settings, otherwise the history of correspondence will be lost when reinstalled.
Recovery of data from backup
The recovery process is as important as creating a copy. If you used the local method, go to the same Settings menu → About Phone → Backup, select the desired date and click Restore. The system will request a password and begin unpacking the archive.
When you restore from the Mi Cloud or Google cloud, the process starts automatically when you first log in to a new device or after a reset, you will be prompted to select a restore point from the list of available dates.
⚠️ Warning: Do not interrupt the process or turn off the smartphone screen during recovery. Interrupting the data record may damage the file system or cause applications to malfunction.
After the procedure is completed, it is recommended to restart the device, which will allow the system to correctly register all recovered components and establish background synchronization.
💡
Regularly backing up (at least once a month) will save you from losing important data in case of sudden system crashes or device theft.
