I have rooted my phone and I need help backing up everything. Can I rely on Google to backup my Contacts, Settings, etc to their servers? How Can I backup my entire phone to my computer so I can reinstall later if something happens? I have read where you can backup to SD card, but are they talking about an external sd card, or an sd card that comes standard in the phone? How can I backup up my photos, videos, documents online? Dropbox?
