Back up and restore using Titanium Backup Pro on my Optimus G2x was easy since it has SD card, I can back up my data on SD card but Nexus 4 lacked the SD card slot, is it even possible to restore my data after factory reset on my Nexus 4? I try using Titanium Backup to back up my data to my Google Drive and Dropbox but I don't see any way to restore my data from either Google Drive or Dropbox back to my Nexus 4.
