SqlBulkTool is a command line utility that is used to quickly create a mirror of a database. It reads its configuration from an XML file containing source and destination command strings and a list of all the tables to mirror and then handles the work of copying the database in an automated and highly parallelized way.
The parallelism can use the partition capabilities of SQL Server 2005: to handle a huge table it is enough to partition it to make the tool load it by running each single partition in a separate thread, dramatically increasing table load time. In the case where no partitioning is defined the parallelism is handled at the table level.
