Hello, friend!
1. Use Cloud backup
Use Cloud backup to back up your device data automatically or manually:
Automatic backup:
Go to Settings > Log in with HUAWEI ID > Cloud > Cloud backup and enable Cloud backup. Your device will be automatically backed up once every seven days when charging with the screen locked and connected to a Wi-Fi network.
Manual backup:
Cloud 10.6.2.300 or later:
In Cloud 10.6.2.300 or later, you can select specific items to back up or restore for Gallery and third-party app data. To do so, connect your device to a Wi-Fi network, go to Settings > Log in with HUAWEI ID > Cloud > Cloud backup > Backup options, select the data items you wish to back up, and touch BACK UP.
Cloud in versions earlier than 10.6.2.300:
Connect your device to a Wi-Fi network and go to Settings > Log in with HUAWEI ID > Cloud > Cloud backup. Touch BACK UP to start the backup.
