"(WhatsApp) How do I use Google Drive backup?

You can back up your messages and media to Google Drive so that if you lose your phone or switch to another Android phone, your chats are safe. We recommend connecting your phone to Wi-Fi prior to backing up your chats via Google Drive, as backup files may vary in size and may consume mobile data, causing additional charges.

If you have time to test, I would love to see what your tool could recover from a WhatsApp Google drive backup versus related data stored on a phone itself.

I am *guessing* that Google Drive would be storing the WhatsApp archive file as a SQLite database that could be carved, but maybe not……

For example, is there actually a level of deleted data that could be recovered from the Google drive backup that might surprise us?

It would be relatively ease to test this on one's own phone using the provided steps below.

If I am reading the below correctly, WhatsApp is stating that one can create a Google Drive backup of an Android phone's WhatsApp to ANY Google drive account, not just the phone's registered Google account which could mean easy collection for us forensic folks.

As I know Line has workstation version, but no database stored on the workstation, somehow we could still find some chat messages in the pagefile. Of course if there are some backups and SQLite dbs are inside these backup files, it will be a great help.

I will take a look at WhatsApp and see if I could recover deleted chat messages.
