UDR is a wrapper around rsync that enables rsync to use UDT protocol and
|
|
thus improves throughput of large data transfers over long distances.
|
|
|
|
UDT is a UDP-based, application level protocol. 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 -av /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.
