It’s because you are using the same google account for backups. Everything looks fine
Thanks for the quick help, I'll have to create a bunch of google accounts then

Hi I just checked my server recently and found that my world wasn't how I left it, but when I checked my backups, they were all from the other Aternos servers I have, and not the server I was looking at. Is this a mistake or did the backups possibly get overwritten because they are all connected to the same Google Drive account? (It was previously set to the Sky Factory 4 modpack (latest edition)) (p.s. I know that you won't be able to get the previous backups and I'm just asking for information so that I know for the future)
