Owning a modern smartphone involves storing a huge amount of personal information, from work documents to family archives. Data loss when you break, steal or accidentally reset your settings can be a disaster, so regular copying of information is not just a recommendation, it is a necessity. In the Xiaomi ecosystem, this process is implemented as flexibly as possible, offering many scenarios for different types of users.
Before we take action, it is important to understand what we are saving, as backups can affect different levels of the system, such as contacts and messages, full system images, or selective media files, each method has its own advantages and limitations in speed, scope and ease of recovery.
In this article, we’ll break down all the available backup methods on MIUI shell devices and the new HyperOS. You’ll learn to use cloud services, on-premises storage, and computer utilities to maximize the security of your digital assets.
Preparation of the device for the redundancy procedure
Starting any maintenance process requires proper preparation, and making a copy of the data is no exception. The first step is to check the free space, as modern applications and photos can take up tens of gigabytes. Make sure that there is space available on the device or in the cloud that exceeds the amount of data being copied by at least 15-20%.
A critical aspect is battery level: interrupting the recording process due to battery discharge can damage backup files or even system failures, connect your smartphone to a power source or make sure the charge is at least 60-70% before starting the operation.
Connection stability should also be taken care of if you plan to use cloud services. Switching between Wi-Fi and mobile can interrupt the load, so it is better to use a reliable home network. Check the accounts that will be used for sync, making sure that the passwords from them are current and known to you.
Use of the built-in local backup MIUI
The fastest and most Internet-independent way is to use a regular system tool. This method creates a full picture of the device's state, including settings, applications and their data, storing everything in the phone's memory. To access the feature, you need to go to the Settings menu → About Phone → Reserve and Restore or search for settings by entering a "reserve" request.
In the menu that opens, the system will suggest selecting data categories to save, you can tick system settings, calls, messages, and installed applications, and pay special attention to the item "Other data", which often hides important settings of specific programs.
☑️ Checking before local backup
Once you have selected categories, click the "Start Reservation" button and set a password to encrypt your archive. Encryption protects your data from prying eyes, but if you forget the password, it will be impossible to recover the information. The process can take from a few minutes to an hour depending on the amount of data and the speed of the drive.
Where is the local copy stored?
Synchronizing data through Mi Cloud
The manufacturer’s cloud service provides a convenient way to automatically synchronize key data, and when activated, contacts, notes, voice recordings, and calendars are instantly updated on the server whenever they change, ideal for those who change devices frequently or fear physical loss of the gadget.
To set up, go to Settings → Mi Account → Mi Cloud. Here you will see a list of data categories with switches. Activate sync for those items that are important to you, and click Sync for immediate update.
Keep in mind that only 5GB of space is available for free, which may not be enough for high-resolution photos and videos, but that is usually more than enough for text, contacts and settings, and you can add an additional tariff if you need it, which will automatically expand storage limits.
💡
Use the Device Cleanup feature in Mi Cloud to remove photos already uploaded to the cloud from your phone and free up space, leaving them available for viewing through the gallery.
Backup in Google Services
Google’s ecosystem is the standard for Android and offers a reliable way to save data. Unlike a local backup, a copy in Google Drive is tied to your account and makes it easy to recover data when you switch to any other Android smartphone. Management is carried out through the Settings menu → Google → Backup.
The system allows you to save the list of applications, call history, SMS-messages MMS, It is important to note that the application data is only saved if the developer is supported by Google Play services, which occurs automatically when you connect to Wi-Fi and charge, but you can force it to start by clicking the "Start copying" button".
Special attention should be paid to synchronizing photos through Google Photos, which creates unlimited (in compressed quality) or volumetric (in original) storage of your images, regularly check the sync status of the application to make sure that the latest images have already been uploaded to the cloud.
💡
The combination of Mi Cloud and Google Services provides dual protection: if one service is temporarily unavailable, the data will remain in the other.
Creating a full copy on a computer
For maximum reliability and an accurate copy of all the contents of the memory, it is recommended to use a computer. This method allows you to create a physical copy of files that cannot be deleted by a remote hack or software failure of the cloud service. USB and the installed Mi program PC Suite or standard file explorer.
When connecting via USB, select File Transfer (MTP) mode. In this mode, the smartphone is defined as an external drive, and you can manually copy the DCIM (photo), Download, Documents and others folders to your computer's hard drive. This is a simple but effective way to save media files.
For deeper redundancy, you can use third-party utilities such as AdbLink or ADB Command Prompt. This method requires the USB debugging mode enabled in the Developer Menu. adb backup -all -f backup.ab allows you to create an archive of applications and data, although support for this feature in new versions of Android is limited.
| Copying method | Speed of operation | Network dependency | Type of data stored |
|---|---|---|---|
| Local backup | Tall. | Not required | Full system image |
| Mi Cloud | Medium | Wi-Fi required | Contacts, photos, settings |
| Google Drive | Medium | Wi-Fi required | Applications, SMS, settings |
| USB-cable) | Very high. | Not required | Files and media |
Data recovery after resetting
The recovery process depends on the previous method of backup. If you used a local copy, after resetting (or when you first set up a new phone) in the Applications and Data menu, select Restore from local copy. The system will find the archive in memory and offer to restore the data by requesting a previously set password.
When using cloud services, everything happens automatically when you sign in to your account. Once you log in to your Mi Account or Google, the system will prompt you to select a restore point from the list of available dates, select the desired version and start a process that can take a long time with a large amount of data.
⚠️ Note: When recovering from a local copy to a new version of Android (for example, switching from a local copy to a new version of Android) MIUI 14 on HyperOS) some settings or application data may not be compatible and may not recover correctly.
To return photos and documents copied manually to your PC, simply plug your phone and transfer the files to the appropriate directories. Media files are usually recognized automatically by the system after the device is restarted.
What to do if the backup is not readable?
Frequent errors and ways to fix them
When backups are created, users often experience process interruptions or write errors. One common reason is the power saving mode, which can "sleep" the copying process when the screen is off.
Another problem is the lack of space, which can manifest itself in the middle of the process. The system may not correctly calculate the required volume, so always leave a few gigabytes of storage. If the error recurs, try clearing the cache of the Security or Google Play Services app before you try again.
⚠️ Warning: Never interrupt the process of firmware or data recovery by forced reboot, which can lead to the "bricking" of the device or loss of part of the file system.
Regular copy creation is a guarantee of security. Set up an automatic schedule in Mi Cloud or Google Drive so you don't have to worry about manually running procedures. Weekly backup will minimize data loss in the event of unforeseen situations.
💡
Checking the integrity of the backup is a must: try opening the backup file or viewing the photo in the cloud immediately after you create it.
