Does a Google Drive WhatsApp backup restore newer mesages? Say I have backed up WhatsApp to Google Drive on some date X, then I uninstall it or format the device. On a later date Y, I reinstall WhatsApp and restore the Google Drive backup. Would the messages sent between dates X and Y be included in said backup?
How could somebody restore something that he doesn't even have?
your Gdrive backup will restore the messages till date X.

If your WhatsApp was active between date X and Y then you would have already received the messages in your WhatsApp(whom you didn't back up on the Gdrive).

So on date Y if you reset your phone and restore the backup from date X then you will have messages up to date X only. and if you didn't use the WhatsApp by date X &amp; Y and you just installed it again now then all the undelivered message between X &amp; Y will be delivered right now.
