How to make a backup on Android?

there are several ways when I faced such a problem I looked at this site https://android-smartfon.ru/firmware-proshivka/kak-sdelat-bekap-proshivki-android

here everything is simple in detail and is described in detail. Also the network is full of videos on how to do it :)

Through twrp you can, there is still Clockworkmod recovery (CWM)

In short, if there are instructions for installing them on your phone (at least one), then you can try, otherwise I do not recommend this case, so as not to spoil the device, but the possibilities are something like this:

Clockworkmod recovery (CWM)

• Install unofficial firmware
• Install add-ons and fixes
• Connect to PC via USB in removable storage mode
• Connect to PC via USB in ADB mode
• Create a backup of both the entire firmware and its individual parts (system, settings, installed programs)
• Recover data from a previously created backup
• Reset data to factory settings (Wipe - data / factory reset), clear the cache partition (wipe cache), clear dalvik-cache (wipe Dalvik-cache), clear battery statistics (wipe battery stats)
• Format and create partitions on the memory card
