How to make a backup (backup) on Xiaomi Redmi 9T: all working ways

Xiaomi Redmi 9T is a popular smartphone with a balance of price and performance, but even it is not immune to crashes, data loss or the need to reset to factory settings. Without a backup (backup), you risk losing contacts, photos, messages and application settings. In this article, we will discuss 5 proven ways to create a backup on the Redmi 9T, including built-in MIUI tools, cloud services and advanced methods for power users.

The Redmi 9T features a hybrid firmware based on Android 10/11 with a MIUI 12/13 shell, which offers its own backup tools, but they do not always cover all needs: for example, the standard MIUI backup does not store data from some third-party applications. So we will consider alternatives from Google Drive to custom TWRP (for users with an unlocked bootloader).

Important: the backup procedure depends on the target, if you're planning a factory reset, cloud redundancy is enough, and if you're going to have to run a Fastboot or replace a motherboard, you'll need a full backup via TWRP or ADB.

1. Standard backup via MIUI (no root)

The easiest way is to use the built-in Backup feature in MIUI. It saves:

  • ๐Ÿ“ž Contacts, call log and SMS
  • ๐Ÿ“ท Photos and videos (optional)
  • โš™๏ธ System and application settings (Wi-Fi, wallpaper, sounds)
  • ๐Ÿ“ฑ Data from some system applications (e.g. Notes or Calendar)

To create a backup:

  1. Open Settings โ†’ About the phone โ†’ Backup.
  2. Click Create a backup and select the data to save.
  3. Specify storage location: internal memory or Mi Cloud (requires Xiaomi account).
  4. Confirm the action and wait until it is completed (may take 5-15 minutes).

โš ๏ธ Note: This method does not store data from third-party apps (such as WhatsApp, Telegram or games) and will require separate backups or the use of Titanium Backup (requires root).

At least 30% of the battery is loaded

Enough free space (backup weighs 1-3 GB)

Wi-Fi connection (if you use Mi Cloud)

Memory optimizers are disabled (they can interrupt the process)-->

2. Backup through Google Drive

If you use Google, this way you can recover data on any Android device, and unlike MIUI Backup, it saves:

  • ๐Ÿ“ฑ Contacts, calendars and tasks (via Google Contacts)
  • ๐Ÿ“Ž Files and photos (via Google Photos)
  • ๐ŸŽฎ Data of certain games and applications (if the developer supports Google Play Games)

FAQ: Frequent questions about backup on Redmi 9T

๐Ÿ”น Can I make a backup without a computer?
Yes, use the built-in MIUI Backup or Google Drive. A full backup (including apps) without a PC will require TWRP, but installing it requires unlocking the bootloader.
๐Ÿ”น How much space does the backup take?
Depending on the method: MIUI Backup: 1-3 GB (no photo / video); Google Drive: up to 15 GB free (photos in "High quality" are not included in the limit); TWRP: 5-10 GB (full system image).
๐Ÿ”น How to transfer the backup to the new Xiaomi phone?
If the new phone is Xiaomi, use MIUI Backup: Copy the backup file (MIUI/backup/AllBackup folder) to the new phone. In the new device settings, select Restore from the backup. Other brands will suit Google Drive or manual file transfer.
๐Ÿ”น Why the backup broke in half?
Possible causes: ๐Ÿ”‹ Low battery charge (at least 50 required%). ๐Ÿ“ถ Unstable Internet connection (for cloud backups). ๐Ÿ›‘ Memory Optimizer Kills Process (Switch It Off in Battery Settings). ๐Ÿ”Œ Problems with USB-Cable or port (try another cable).
๐Ÿ”น Can I restore the backup after changing the firmware?
Yes, but with the caveats: If the firmware is the same version of MIUI, the recovery will be smooth. If the firmware is newer, restore only Data, not System. If the firmware is custom (for example, LineageOS), the MIUI backup will not work.
