I have a Fairphone 2 running their OpenOS. It is Google-free and rooted. I have a 128GB SD card installed, added to the 32GB that comes with the phone.
I suspect that my SD card might be failing. I would like to test this by switching to a new card. I do have a 64GB card I can use, and I do have enough free space that it'll all fit.
The question is, how? I use both TWRP and Titanium Backup, but neither of them backs up the majority of my data. They basically just do apps.
I can rsync from the phone to a computer, but it's far from clear how I would restore. I guess I'd end up having to piece things back together one directory at a time.
I really want something that will backup and restore the entire phone. Is there any way to do this cleanly?
Alternatively, is there any way to fsck the SD card?
