Xiaomi Reservation: What is this program and why you need it

Many Xiaomi smartphone users, when they first get acquainted with the shell of MIUI or HyperOS, encounter a system notification or menu item called “Reservations.” Often the question arises: what kind of program is it, can it be removed and is it not a virus?

The main task of this mechanism is to save critical user data, such as contacts, call history, SMS-Xiaomi has implemented several levels of information protection, so that in the event of a device loss or a software failure, you will not be left without important numbers and correspondence. Understanding the principles of this tool will help to avoid data loss when flashing the gadget.

Unlike simple file copyers, system backup can work with protected memory areas that a normal file manager cannot access, which is why using embedded tools is preferable to manual file transfer, and then we will discuss in detail what types of backup are available, where they are stored and how to properly configure automatic data storage.

⚠️ Attention: Deleting or forcibly stopping the system process "Reservation" through the developer settings may make it impossible to restore data with regular funds.

Types of Backup in Xiaomi Ecosystem

Xiaomi’s ecosystem offers a flexible data storage system that is divided into three main areas: the choice of the specific method depends on your storage needs and recovery speed, and it is important to understand the difference between them, so as not to rely on only one source.

The first and most reliable for most users is local reservation, which is stored in the phone's internal memory or on the phone. SD-It's a fast way, it doesn't require the Internet, but it's useless if the device is physically lost or damaged permanently. The second type is the Mi Cloud service, which syncs data with the manufacturer's servers. The third option is to use standard Google tools, which are also deeply integrated into the system.

Each method has its own advantages and limitations in terms of free space: Local copy can take up gigabytes, whereas the cloud is often limited to 5 GB for free, and a combination of methods allows you to create a really reliable insurance against loss of information.

• 📱 Local backup: stored in device memory, ideal before flashing or resetting settings.
• ☁️ Mi Cloud: synchronize contacts, galleries and notes through your Mi Account.
• 🔒 Google Drive: Reserving Wi-Fi app settings and passwords through your Google account.

Local backup: where files are stored

Local copying is the gold standard for preparing your smartphone for radical actions, such as factory resets or custom firmware installation. When you create a local copy, the system packs selected data into a special archive that is hidden from normal viewing in the gallery or file manager by default.

The path to these files is strictly regulated by Android. The archives are stored at MIUI/backup/AllBackup in the root directory of internal memory. If you connect your phone to your computer in file transfer mode (MTP), you can see this folder and copy its contents to your hard drive. This is critical if you plan to format your phone.

The volume of the copy created depends on the amount of data selected. Photos and videos can occupy a significant space, while contacts and other data are not available. SMS-Messages weigh kilobytes. Before starting a process, the system always shows the file size.

To create a local copy, you need to go to the settings menu. The path may vary slightly depending on the version of the shell, but it usually looks like: Settings → About the phone → Reserve and restore. Here you can choose what you want to save: system data, applications, pictures or music.

⚠️ Note: When resetting your phone (Hard Reset) folder MIUI/backup It will be completely deleted along with all other content. Be sure to copy the created archive to a computer or external drive before formatting.

Configure cloud synchronization Mi Cloud

The Mi Cloud cloud storage is a proprietary development similar to Apple’s iCloud, which keeps data up-to-date on all devices tied to a single Mi Account, especially for users who frequently change smartphones or use a tablet and phone at the same time.

Unlike a local backup, the cloud runs in the background. Once you take a new picture or add a contact, information is sent to the server. The service requires a stable Wi-Fi or mobile Internet connection. Free 5 GB of space is provided to the user, which can be expanded for a fee.

The sync is set up through the account section, you need to log in and select categories to save, and the system will decide when to download the data, so as not to waste traffic on roaming, unless you set other parameters.

Backup through Google Account

And the standard Android engine, which works in parallel with Xiaomi’s tools, is Google’s services that saves Wi-Fi passwords, call history (on some models), system settings, and app data that supports this feature, an “invisible” backup that is automatically restored when you first log in to a new device.

You can check the status of the save in Settings → Google → Backup. This shows the date of the last successful data upload and the list of applications whose data is stored. Unlike Mi Cloud, this is encrypted with your account key, which increases privacy.

The thing about this method is that it doesn't create a single file that you can see, it's broken down into small pieces and stored in a secure container, and you can only recover it when you first set up Android or reset it completely.

• 🔑 Passwords and keys: saved in Google Smart Lock, available on all Android devices.
• 📞 Contacts and Calendar: synced instantly with a network.
• 📷 Photos and Videos: require a separate setting in the Google Photos app (Selecting the quality of "Saving Place" or "Original»).

Recovery of data from backup

The Restore process is as important as copy creation. If you have saved data locally, you need to re-enter the Backup and Restore menu, find the archives available, and then select a date, and then you start unpacking the files and integrating them into the system.

When you restore from the Mi Cloud or Google cloud, the process often happens automatically when you log in to an account on a new or reset device. The phone will ask if you want to restore data from a previous copy.

Recovery time depends on data volume and Internet connection speed (for cloud methods), local recovery is much faster, as it does not depend on the bandwidth of the communication channel.

💡

When you restore from a local copy, applications may not automatically install if they are not in the Play Market store or have been removed by the developer.

⚠️ Warning: Do not interrupt the recovery process by turning off the screen or closing the application. Interrupting may damage the contact database or cause refurbished applications to malfunction.

Frequent problems and their solution

Users may experience errors when creating or restoring backups, most often a lack of space or an unstable Internet connection, and conflicts may also occur if the version of Android on the device that is backup is significantly newer or older than the version on which the recovery is being done.

If the process is stuck at a certain percentage, try clearing the cache of the Reservation application through the application management menu. In some cases, rebooting the device before starting an operation helps. For cloud services, it is important to check whether the password from the account has expired and whether there is access to the network.

Difficulties may arise when trying to restore a full copy of the system (the backup of the entire phone) to a device with a different model or firmware region, in which case it is recommended to restore only user data (contacts, photos), and not system settings.

💡

Regularly creating local copies before any changes to the system is the best protection against data loss in firmware experiments.
