Proper preparation before copying will help to avoid errors and ensure the integrity of your files. Let’s look at tools that will help to protect your digital life.
Preparation of the device and selection of the archiving method
Before you start directly copying files, you need to perform a number of preparatory steps that will ensure the stability of the process. First of all, check the battery level: it should be at least 50-60%, as the procedure can take a long time and the energy consumption at this point increases. Also make sure that the device has sufficient free space if you plan to create a local copy on an internal drive or memory card.
It's important to decide on the type of data that needs to be saved, whether it's system settings and contacts, or a full array of media, including high-resolution video and app cache. Redmi 3 is characterized by separation of memory into system partition and user partition, so understanding the file structure will help you choose the right storage.
There are three main ways to solve the problem: using the cloud service Mi Cloud, creating a local backup by shelling. MIUI or synchronize with the PC through USB-Each method has its advantages: the cloud is convenient for contacts, the local backup is fast for system recovery, and the PC is reliable for large amounts of data.

The process of creating an archive takes from a few minutes to an hour depending on the amount of information.
☑️ Checking before creating a backup
When the operation is complete, the backup file will be stored in a hidden folder of the system, which requires you to enable the display of hidden files through the file manager or use a special path. The local backup is especially useful before you run the device or obtain root rights, as it allows you to quickly return the phone to working condition.
⚠️ Note: The local copy is stored in the phone's internal memory, and if the device is completely lost or physically damaged, it will not be possible to recover the data from this file without previously transferring the copy to the PC or to the cloud.
Sync with Mi Cloud and Google Account

Frequent problems and ways to solve them
Xiaomi Redmi 3 users may encounter various technical difficulties in backing up. One common problem is the “Not enough space” error, even when there is free space, often due to file system fragmentation or the system reserving space for temporary files that are not displayed in the shared counter.
Another common situation is interruption of the sync process with the cloud, which can occur due to unstable connection or aggressive MIUI energy saving policy, which kills background processes. To avoid this, add sync services to the battery exclusion list and allow auto-start.
If the computer does not see the phone MTP, try to replace USB-cable to original or better quality, as cheap cables often only support charging. USB Driver to your computer. Rebooting both devices often solves handshake problems.
