Do NOT disable binary log on a production server. It's not only needed for replication, but for recovering the entire database to a point of time. One would normally do periodic backups of the database, but if the database crashes and you need to recover it, even with backups, modifications done between the last backup and the crash will be lost if there's no binary log. With the binary log you can restore the last backup and then re-apply the modifications stored in the binary log until the crash, so the data loss is minimum.
