I along with a friend are having an issue with the backs ups, they aren't working on my friends SMP server we tried updating to 1.18 but sadly one of the plugins we all enjoy wasn't there so we changed it back to 1.17 we also did back it up before going into 1.18 so that we could go back just in case. Thing is when we went back to 1.17 we got reverted about a week back and players were playing before then so auto save should have saved it at least at the day before. We went from about day 450 - 398 lost farms progression, items, etc. and the backup will not load. I also tried making a new backup on a creative server we use and tried restoring the backup, nothing it was the exact same. We restarted the server, had it hibernate and still nothing, we've also both received "Unknown Error" when attempting but also have both had experiences of the servers saying "Downloading" then still doing nothing world wise or player wise or server wise. This is very disheartening because now it feels as if we are being punished for going back to 1.17 even though we set a backup before 1.18 is backup currently just broken? If so how long will it take to resolve?
