How to speed up robocopy

Solution 1:

Can I add any options to increase the performance of the robocopy command?

The following options will change the performance of robocopy:

• /J : Copy using unbuffered I/O (recommended for large files).

• /NOOFFLOAD : Copy files without using the Windows Copy Offload mechanism.

• /R:n : Number of Retries on failed copies - default is 1 million.

• /W:n : Wait time between retries - default is 30 seconds.

• /REG : Save /R:n and /W:n in the Registry as default settings.

• /MT[:n] : Multithreaded copying, n = no. of threads to use (1-128)

  default = 8 threads, not compatible with /IPG and /EFSRAW.

  The use of /LOG is recommended for better performance.
