      Description

      On startup, the server attempts to create a backups folder as ../backups (i.e. a folder one folder up from its work location/"universe"), apparently for use when converting non-anvil worlds. This is problematic, because e.g. on shared hosts this location may not have write access, so the server will fail to start (but even ignoring that issue, it is confusing to put the backups folder outside of the server itself ("why is there suddenly an empty backups folder here?")).

      The failed startup can be reproduced when launching a server on windows within your user directory (C:\Users\<USERNAME>) from an account that doesn't have permission to write to C:\Users. Doing so causes the server to fail to start, with this error message (quoting Dusty A from MC-122621):

      Box itself is only a couple of months old. Have done all the obvious, updates & patches all to latest. Deleted and re-downloaded jar file etc.

      Working fine with last weeks snaps by no joy with this one.

      Edit: Same behavior is 17w47b
