THE INFORMATION IN THIS ARTICLE APPLIES TO:
Microsoft Robocopy, included with the Microsoft Windows Server® 2003 Resource Kit, is a utility for copying data. Robocopy does not have some of the common limitations of Windows Explorer or a Command prompt.
WAFS customers often use the following Robocopy switches:
- /E = copy subdirectories, including Empty ones
- /V = produce Verbose output, showing skipped files
- /B = copy files in Backup mode
- /R:n = number of Retries on failed copies; default 1 million
- /W:n = Wait time between retries; default is 30 seconds
- /NP = No Progress - don't display % copied
- /LOG:file = output status to LOG file (overwrite existing log). e.g., /LOG:wafs.txt writes to wafs.txt
- /TEE = output to console window, as well as the log file
- /FP = include Full Pathname of files in the output
- /DCOPY:T :: COPY Directory Timestamps. [Only for use with Windows 2008 R2 and Windows 7]
- /XO :: exclude older files
- /MT:n = copy using multithreading; n is the number of threads up to 125 [Only for use with Windows 2008 R2 and Windows 7]
