It is recommended to use cloud backup to save important data to avoid loss.
(Take the Coloros11version of OPPO RenoAce mobile phone as an example. )
1. Automatic backup operation path of cloud backup: enter "Settings >" of mobile phone; Cloud service > machine backup > set backup data type > automatic backup. After turning on the automatic backup switch, when the mobile phone is turned on and connected to WLAN, the data you selected will be automatically backed up to the cloud, once every 7 days.
Manual backup: go to settings > cloud service > whole machine backup > set backup data type > backup now. After clicking the "Back Up Now" button, the cloud service will immediately back up the data you selected to the cloud.
2. The specific operation path of backup recovery:
Go to settings > cloud services > machine backup > click restore data > select this backup to restore the previously backed up data.
3. What can be backed up and restored:
ColorOS 1 1: whole machine backup.
ColorOS 7: SMS, call record, Breeno speedbar, application list and layout, system settings.
Coloros5.1-coloros6.1:SMS, call records, application list and layout, system settings.
Coloros3.1-coloros5.1:SMS, call records, system settings.
Tips:
① Only versions of ColorOS 1 1 or above can support the backup of system data such as address book, photo album, audio, documents and WeChat data.
② Considering that using mobile data network for cloud backup will consume more data traffic, it is only recommended to operate when connecting WLAN for cloud backup or recovery.
Due to the different versions of the mobile phone system, the operation path may be slightly different. Please refer to the actual operation interface display of the mobile phone.
This answer applies to all OPPO models.
