Repdump.exe must be run on the server that runs the ITP/MDK Repository. It is installed in the root of the ITP/MDK Server installation and it must not be moved since it needs the Server Initialization file that is located in that folder.
Repdump is used from the Command Line and takes just one parameter; the path/name of the file it will export the ITP/MDK Repository database to. If no path is provided the file will be written in the current folder.
Repdump writes a log, Repdump.log that can be found in the folder it is installed in.
Repdump "path\database dumpfile name"
