It is designed to +support transferring large datasets over high speed wide area networks, +where TCP has been known to be extremely ineffective. + +UDR does not change rsync, it works by creating a UDT connection and +then places the connection between the rsync client and server. + +To use UDR, prefix the current rsync command used to transfer data with +'udr', for example: + +udr rsync -avz /home/user/dir/ user@example.com:/home/user/dir + +Any rsync options can be used. + +UDR must be on the client and server machines that data will be +transferred between. UDR uses ssh to do authentication and automatically +start the server-side UDR process. At least one UDP port needs to be +open between the machines. |
