WhatsApp: incremental backup possible? I share my phone at home and I know sometimes some of my WhatsApp messages are deleted from my chat history. Sometimes I end up dieting some videos from WhatsApp myself due to lack of space on the device. I would like to know whether it is possible to perform an incremental backup to Google Drive, so that I can restore a video or part of a chat from any date in case I decide to delete it locally and the standard WhatsApp backup to Google Drive deletes this part. Thanks.
WhatsApp backup on Google Drive is incremental as you can read in WhatsApp FAQ

But you can't restore a video or part of a chat from any date in case I decide to delete it locally.....,that's not possible and you would need to restore in full not selectively by date or content
