Absolutely! See the blog for more details: http://blogs.splunk.com/2013/01/04/shuttl-a-new-year-a-new-release/
In short, Shuttl understands how Splunk is replicating buckets, and will utilize that replication for reliable transfer to the back-end storage system. In addition, Shuttl will prevent duplication of buckets on the backend.

This is completely avoided by using Shuttl.
