A few days ago my new phone got damaged after a fall and I have to send it to ASUS to fix it since there's no in store assistance for ASUS phones in my country. I was told it will be factory reset to ensure my privacy despite the fact the damage is external, so I wanted to find a way to have a full backup (apps, settings, data, life universe and everything...) but from what I read on the internet tools such as Titanium and Helium backup are not working anymore on new phones (mine is running on Android 12) so I didn't even bother, also I can't use methods that require rooting since that will void my warranty and the phone is only few months old.
I tried running the command
adb backup -apk -obb -shared -all -system -f fullbackup.ab but after a while it stops creating an incomplete backup, it stops at around 17-19 GB, always a different number, while my phone has 100GB of data to backup. The first time after a backup I tried extracting it but the process exited saying it was an incomplete archive.
I read that this might be cause by active apps, I tried closing them but it didn't help (guess it's some system app), I also found that sometimes it might be caused by not setting a backup password, but that didn't work either
So I would like to know if there's either a better way to fully backup my phone in 2023, or how to make adb backup work
