Why backing up on the Mi A2 Lite is not a luxury, itโ€™s a necessity

Xiaomi Mi A2 Lite (codenamed daisy) is still popular with users due to its balanced features and support for custom firmware. However, its age (released in 2018) and limited internal storage (16/32 GB in the basic versions) make backup critical. One failed factory reset โ€” and you can lose years of WhatsApp correspondence, saved passwords, photos in DCIM or even data from banking applications.

Unlike the flagships with a reserve of memory, the Mi A2 Lite often works "back-to-back": users delete the cache, transfer files to the Internet SD-The card (if supported) and encounter errors when updating Android, a feature of this model is the lack of official support. MIUI 13+ Android 12+, So backup needs to be multi-level: separate for applications, separate for system settings, and always with the ability to restore to another version of the software.

Method 1: Standard backup via MIUI (for users on official firmware)

If your Mi A2 Lite runs on MIUI stock firmware (even an outdated version), use the built-in backup tool.

  • ๐Ÿ“ฑ System settings (Wi-Fi, wallpaper, sound profiles)
  • ๐Ÿ“ Application data (not all, but only supported)
  • ๐Ÿ“ž Call log and SMS
  • ๐Ÿ”‘ Accounts (but not passwords!)

To create a backup:

  4. Wait until the end (it can take 10 to 30 minutes depending on the amount of data).

โš ๏ธ Note: This method does not save gallery photos, music or downloaded files, but must be copied manually through Explorer or by connecting the phone to a PC. MIUI It will not recover on custom firmware (e.g. LineageOS or Pixel Experience).

Method 3: Full backup via TWRP (for advanced users)

If you plan to install custom firmware or want to keep a full copy of a partition (including /data, /system, and /boot), the only reliable way is to use TWRP Recovery.This method requires an unlocked bootloader and a TWRP installed, but gives you 100% control over backup.

If TWRP fails to detect SD-Map, try: 1. Format the map into FAT32 2. connect the card through OTG-Adapter (if the slot is not working) 3. Update TWRP Up to the latest version (old builds may not support exFAT). 4. Check the card for errors through chkdsk in Windows.

Method 4: Backup through ADB (for developers and without root)

If you don't have TWRP, but you have access to ADB (Android Debug Bridge), you can back up your computer, which doesn't require root rights, but has limitations: some applications (like banking) block backups of their data.

What you need:

adb restore C:\backup_mi_a2_lite.ab

โš ๏ธ Attention: Backup through ADB includes SMS, call log and Wi-Fi settings on some firmware, and use separate applications for these, such as SMS Backup & Restore.
