Automatic Backup
Backs up the save folder when the game is started and on each save attempt (with a configurable cooldown and limits on the number of backups of each kind).
To adjust the config, edit AutoBackupConfig.xml in the default LibraryOfRuina save folder after the first launch with the mod (or copy the template from the mod folder).
Backup copies are created next to the main LibraryOfRuina save folder (higher numbers mean older backups among these of the same kind).
