Xiaomi system backup: how to save all data before resetting or firmware

Why Xiaomi Backup Is Not a Luxury, It’s a Necessity

Have you ever lost important photos, contacts or messages because of a factory reset? Or have you ever had a situation where Xiaomi stopped turning on after a failed firmware and all the data disappeared with it? Backup is a hedge against such trouble. Even if you're a neat user, no one is immune from accidentally deleting files, viruses or hardware failures.

Modern Xiaomi smartphones based on MIUI offer several ways of backup, from built-in tools to third-party solutions like TWRP or ADB. But not all methods are equally reliable. For example, cloud backup via Mi Cloud will not save system settings, and local backup through Settings → Additional → Backup may not restore some applications. In this article, we will analyze all available methods, from simple to advanced, and find out which is right for you.

It is especially critical to do backup before:

• 🔄 Reset to factory settings (for example, before selling the phone).
• 📥 Update your firmware via fastboot or recovery.
• 🔧 Unlocking the bootloader (unlock bootloader).
• ⚡ Install custom firmware (for example, LineageOS or Pixel Experience).

Method 1: Built-in backup via MIUI (local and cloud redundancy)

The easiest method is to use standard MIUI tools. It is suitable for beginners and does not require root rights or unlock the bootloader. However, it has limitations: some system data (such as Google Pay settings or individual application data) may not be saved.

To create a local backup:

1. Open Settings → About Phone → Backup (on some models, the path may differ: Settings → Additional → Backup).
2. Click Local Backup and select data to save: 📱 System data (wi-fi settings, wallpaper, sounds). 📁 Applications and their data (not all applications are supported!). 📞 Contacts, messages, call log. 📷 Multimedia (photos, video, audio – but it is better to copy them separately!).

MicroSD

For cloud redundancy via Mi Cloud:

• 🌐 Go to Settings. → Xiaomi account → Mi Cloud.
• Turn on synchronization for the desired categories (contacts, notes, photos).
• 🔐 Make sure you have enough space in the cloud (free 5GB).

⚠️ Attention: Built-in backup MIUI does not store data of some applications (for example, WhatsApp or banking programs) and requires separate reservations through the applications themselves.

Battery load (minimum 50%)

Free space on the device (at least 1 GB)

Method 2: Full backup via TWRP (for advanced users)

If you want to save the entire system, including the /data partition with application settings and user data, the best option is to use custom recovery TWRP. This method requires an unlocked bootloader and installed TWRP, but gives the most complete copy of the system.

Instructions for creating a backup through TWRP:

1. Turn off the phone and press Volume Up + Power to enter recovery.
2. In the main TWRP menu, select Backup.
3. Check the boxes for reservations: 📁 Boot - Boot section. 🗄️ System - System files. 📱 Data – User data and settings. 🔄 EFS — IMEI Serial numbers (critical for communication!).

Swipe for confirmation and wait for the process to end.

The advantages of TWRP-backup:

• ✅ Stores all data, including hidden system files.
• ✅ You can restore the system even after a complete failure.
• ✅ Supports incremental backups (save only modified files).

⚠️ Note: If you do a backup before installing custom firmware, make sure the version is TWRP compatible with your Xiaomi model, for example, for Redmi Note 10 Pro (sweet) and Poco X3 Pro (vayu) requires different builds.

Method 3: Backup through ADB (without root but with limitations)

If you don’t have an unlocked bootloader, but want to make the backup more complete than through MIUI, you can use the ADB (Android Debug Bridge) tool, which doesn’t require root rights, but doesn’t work with all applications (many block backups via ADB).

Instructions:

1. Install ADB and Fastboot Tools on PC.
2. Turn on the phone to Debug via USB (Settings → About Phone → MIUI version – press 7 times, then go back to Settings → Additional → For Developers).
3. Connect your phone to your PC and execute on the command line: adb backup -apk -obb -shared -all -f C:\backup.ab Where: -apk — retain APK-file. -obb — Stores additional data from the applications. -shared — includes files from internal memory. -all — All applications (but many may refuse).

On the phone, confirm the creation of a backup (a password may be required).

To recover data from ADB-backup:

adb restore C:\backup.ab

💡

If ADB doesn’t see your Xiaomi, try installing official Xiaomi drivers from en.miui.com or using Google’s universal USB Driver.

Method 4: Manually copying important data (photos, contacts, messages)

Even if you have a full backup done through TWRP or ADB, some data is better duplicated separately, for example, photos in Google Photos or contacts in Google Account can be restored even if the main backup is damaged.

What to copy manually:

• 📷 Photos and videos: Use Google Photos (automatic sync). or copy a folder DCIM PC-only MTP (plug-in).
• 📞 Contacts and Messages: Export contacts to.vcf via Contacts → Settings → Exports. SMS Use applications like SMS Backup & Restore.
• 🎮 Game data: Games with Google Play Games support sync automatically. For others, use Helium (requires root or root) ADB).
• 📄 Documents and Downloads: Copy Download and Documents folders to PC or cloud.

How to recover data from backup on Xiaomi

The way you recover depends on what type of backup you make.

1. Recovery through MIUI:

• Go to Settings → Additional → Backup.
• Select the backup file (usually in the MIUI/backup/AllBackup folder).
• Check the data for recovery and confirm.

2. Recovery through TWRP:

• Load to TWRP (Loudness Up + Nutrition).
• Select Restore and specify the folder with backup.
• Mark the partitions for recovery (usually Data and System).
• Swipe for confirmation and wait for completion.

3. Recovery through ADB:

• Connect your phone to your PC and execute the command: adb restore C:\backup.ab
• On the phone, confirm recovery.

⚠️ Note: If you restore the backup to another Xiaomi model or after changing the firmware (for example, with a new model). MIUI On LineageOS, some data may not work correctly, in which case it is better to restore only user files, not system partitions.

Frequent Xiaomi Backup Mistakes and How to Avoid Them

Even experienced users sometimes have problems with backups, and here are the most common mistakes and solutions:

1. the MIUI backup is interrupted or not created:

• 🔋 Check the battery charge (should be at least 50%).
• 📱 Free up space on the device (minimum 1-2 GB of free space).
• 🚫 Turn it off. VPN Firewalls – they can block the process.

2.TWRP does not see internal memory:

• 🔌 Connect. OTG-drive or use a microSD.
• 🔄 Reboot to TWRP Repeatedly, sometimes helps.
• 📁 Check if the memory is encrypted (if so, a password is required).

3. ADB doesn't backup:

• 🔧 Make sure that the debugging is enabled USB and confirmed PC authorization.
• 📋 Check if the antivirus is blocking adb.exe.
• 🔄 Reinstall Xiaomi drivers or use universal Google USB Driver.

4. Recovery from the backup leads to freezes:

• 🔄 Do not restore system partitions (Boot, System) to another version. MIUI.
• 📱 If the phone doesn’t turn on after recovery, try flashing clean firmware through fastboot.

💡

Before restoring your backup to a new firmware, always check for compatibility with MIUI versions. For example, a backup with MIUI 13 may not work correctly on MIUI 14.
