I have a LG G3 which I have repaired many times (actually by putting it into the furnace xD). Now I'm scared that my phone dies so I do a Titanium and Nandroid Backup every day, but none of these is backing up up my internal storage with my WhatsApp Photos and so on.
Now I had the idea to replace the WhatsApp folder with a link to my SD Card. I have root and tested it with
ln -s /storage/external_SD/test/ /sdcard/test.
ln: /sdcard/test: Function not implemented.
After some research I found out that links are not supported by the file system of the internal storage (I also tried to make a link to the /data/data folder and it worked so it has to be that).
My questions now:
- Is is somehow possible to make a link in the internal storage to the SD Card (e.g. with an Xposed module which emulates a link or something like that)
- Is there a better way of backing up my internal storage?
