MirrorMaker actually doesn't have a default - it uses what you configured in the consumer.properties file you use.
Either: auto.offset.reset = latest (biggest in old versions) or auto.offset.reset = earliest (smallest in old versions) So you can choose whether when MirrorMaker first comes up, if it starts from beginning or end. Note that this is just for first start. Any other restart after, it should use the checkpoints like normal consumers and not lose data (especially in 0.9.0 and above).
