I want to use Robocopy to copy files from my 2nd HD to my external USB HD. I previously copied the entire 2nd HD to the USB drive but now I want to copy to the external drive, only those files that have been changed or added to the 2nd drive.
Can someone tell me what switches would accomplish this using Robocopy?
Thanks,
Greg

What you are looking for is actually the default behaviour
https://ss64.com/nt/robocopy.html
If a source file is edited to a newer (or older) date/time, then robocopy will write it to the destination." By default Robocopy will only copy a file if the source and destination have different time stamps or different file sizes."
The best thing is to grab a few sample files and test the behaviour before running the command against thousands of files.

Simon, I made a .bat file to run this but I'm getting "invalid parameter #4" from the robocopy script and it won't write a log file
.
Here's is what's contained in the .bat file:
Code: Select all
Robocopy "D:\" "G:\GCH Backup\From D Drive" /S /NP /XF Pagefile.sys /XD "My
Documents" "System Volume Information" "Recycler" "Temporary Internet Files"
/LOG:"D:\Backup Stuff\Batch\D_Backup.log"
Source - D:\" G:\GCH\
Dest - D:\Backup\From\
Files : D
Options : /COPY:DAT /R:1000000 /W:30
ERROR : Invalid Parameter #4 : "Drive /S /NP /LOG:Backup"
Appreciate anything you can tell me. I'm using robocopy to copy My Documents from the C: drive to my USB drive with no problems. Can't figure out why copying from my 2nd drive to the USB is not functioning.
Thanks,
Greg

I think your problem is that robocopy uses the backslash '\' to escape certain characters including double quotes
This means that "D:\" gets interpreted as D:\" instead of D:\
So Robocopy is reading [%1] as [D:\" G:\GCH\] not only is that completely invalid but with the quote marks out-of-sync it then proceeds to get confused about what all the other parameters are.
Try just using D:\ without any quotes

"D:\\" should work too...Simon Sheppard wrote:

I had the same problem and looked for a solution that should work when specifying a drive or a directory.
The one I have found is to add a blank character before the leading double quote:
directory name for Robocopy = '\"' + directory name + ' "\'
(allowing blank characters in file names was a false good idea!)

I think you mean adding a space before the trailing double quote, thus:
Code: Select all
robocopy "c:\ " "d:\ "
Code: Select all
robocopy "c:\." "d:\."
