With the Mi account, the Xiaomi smartphone gives us another way to back up our data. Here, the data or backup is backed up in the Xiaomi cloud. This procedure is similar to the Google backup.

Note: A free Mi account must be created and backed up before use. Xiaomi backups can be restored from the cloud anytime, we only need the Mi account data.
