I recently set up bukkitbackup to back up my server worlds instead of cron script that I used previously, and encountered a bug in maxbackups setting.
Maxbackups description says to set value to zero or -1 to disable feature. however, when set to 0, it deleted all but newest backup, and when se to -1, plugin deleted all zip files from backups directory. Both previously existing and new backups. It does still make backups when scheduled or commanded to do so, but deletes them afterwards.
