Duplicator 1.3 now has a new engine format named DupArchive.  This format is specific to Duplicator and is designed around performance and scalability. Many budget hosting providers have very strict timeouts, CPU/IO constraints that they configure into their servers. With DupArchive the format is designed	to help get around these server constraints so that users can build larger packages.  The DupArchive engine is currently only available  in Duplicator 1.3 and above.  This version is currently in Beta and after we have had a good amount of community support we will make it publicly available.
