1. So I see that my google "Backup account" can backup my data and restore apps and there settings and data. So why use Titanium?
2. whats the difference between googles backup and Titanium's?
3. Can I use both together when restoring? I assume google will restore first and then I will restore from Titanium... Is there any reason to restore from google account?
4. And then there's TWRP and its backup: what I understand about this is if I do a backup before I flash Viper Rom then I can flash my backup if I want to return to my old ROM and it will restore the ROM and apps and all data (so I wouldn't need to restore from Titanium and/or google in this scenario?). Is this correct?
