Robocopy is built into Win 7, just go to a cmd prompt, robocopy /? will display all the options and there are alot. The most common ones I use are: robocopy source dest /e /r:2 /w:5 /np /log:path\filename /mt /xo source and dest are the paths or urls to the folders. /e copy all folders and subfolders, even empty ones. /r:2 Retry 2 times on copy failure (can be set to a different number) /w:5 Wait 5 seconds between retries (can be set to a different number) /np Don't display file completion percentage /log:path/filename Keep a log of actions /mt Use multi-threaded copy /xo eXclude Older (Overwrite old files with newer files) Example: robcopy c:\data d:\backup /e /r:2 /w:5 /np /log:c:\robolog.txt /mt Review the logs for any errors.
