[Q] S3 Filing System

Hi

I've just done a factory reset using Titanium Backup and the Nova Launcher backup system. It was a complete disaster (well, maybe not complete--I needed the cleanup) as neither of the backups functioned correctly and I lost all my apps, etc. After restoring from scratch, I did a bit of research. By default, both Titanium and Nova backups were saved to sdcard0 (as opposed to externalsdcard). I'm a relative newbie to the S3, but I think sdcard0 is the internal phone storage and therefore wiped when I did the factory reset. Am I correct?

If so, I have to wonder why both backups defaulted to this storage location. I've since moved both folders to external sd card and changed the backup paths on both apps. To preclude similar disasters, can I rename the somewhat confusing sdcard0 to something more recognisable (internal or phone storage seems reasonable) or would this cause more mayhem? :confused:

If I'm completely out to lunch with all of this, can someone educate me on the mysteries of the S3's storage configuration :o

Thanks in advance
