World Downloading

I uploaded my singleplayer world onto aternos to play with my friends. I do not always want to play on server to due minecraft multiplayer limits and the queue. I have followed the youtube turorial to download the world, but it only gave me the file I originally uploaded. I made sufficient progress like mining out huge areas with my friend. I tried to make the backups to google drive, but aternos does not let you see , download, or replicate those files saved to your drive. It would be a massive help if someone was able to tell me what to do. The thing I can think of would to use a mod to download the chunks of the world, but that would still not be able to encompass everything I have touched and that is not the same. If you know what to do please help me out. Thank you for reading all of this.

I discovered something. I found out that is was my world file, but I had the inventory and attributes of what I was doing, so I will need to get my inventory to get what I had, so I dont accidently dupe anything.

I made a backup of the world before I uploaded and was at my goldfarm. I then mined out a large area with my friend. I then downloaded the world, unzipped it, put it back in my saves folder, and when I rejoined the world I was back at my goldfarm getting xp. I definitly deleted the world before that happened, so the file was definetly the one I downloaded.
