only full backups yet, but i added the feature for individual folders to my todo list You can do backups dynamicly minimal. every hour. Backups can be written into the same folder, or new folders on every backup. also if you have specified an amount of maximal folders, the oldest one will be overwritten if the limit is reached. I havent done a real cpu usage test, but because this gui is only a wrapper, the highest load will come from the java process (bukkit) itself.
