My Android smartphone only has 4 GB and the WhatsApp folder already has 500 MB in the WhatsApp Video sub-folder.
I know I can make a one-time back up my WhatsApp data on the cloud but I need a permanent solution like keeping all the videos older than 3 days on the cloud, in order to permanently save my storage space.
Does WhatsApp have such a feature? It should not be very difficult for them to do that because WhatsApp can keep a single copy for each video shared by millions of different users (and the people share mostly popular videos, not personal videos), therefore the space consumed per user should be quite low.
