Compatibility with Distant Horizons
As of Distant Horizons 2.3, Distant Horizons will generate LODs on the server and send them to clients. However, it stores the LODs in SQLite databases in the data folders of the world (worldname/data/DistantHorizons.sqlite, worldname/DIM-1/data/DistantHorizons.sqlite, worldname/DIM1/data/DistantHorizons.sqlite). These LOD databases can be quite large (my world's is 3.2gb) and git can't version them, leading to large backup sizes. For example, my world is 4gb, and the corresponding FastBack backup (with a fixed retention of 7) is 54gb.
I'm not sure how FastBack could properly version the Distant Horizons database, so maybe FastBack could exclude those files from backups? Maybe with a setting to re-enable, with a warning about large backups?
