One of the benefits of deduplicated systems is that they store only unique data segments, replicating only new segments to remote locations. With the post-process method, you have to wait until the deduplication step is complete until data can be replicated. This can delay the update of the disaster-recovery site by six to 10 hours.
As a result, companies such as Data Domain, Permabit, and Diligent Technologies that started with data deduplication as a core part of their technology have a distinct advantage. Other vendors will have to make post-process data deduplication much more seamless, exit from deduplication altogether, or rewrite their code bases to support in-line deduplication.
